The tomato decoded: holds more genes than humans

The tomato has always been a complex fruit. Or is it a vegetable? Either way. Tomato, tomahto, right?
The tomato, which is considered a fruit by botanists and a vegetable to the US government, has been demystified by a consortium of plant geneticists from 14 countries who spent nine years decoding the tomato genome with the hopes of breeding better, tastier fruits.
Specifically, the scientists sequenced the genomes of both Heinz 1706, a variety used to make ketchup, and the tomato’s closest wild relative, Solanum pimpinellifolium, which is grown in Peru, according to The New York Times.
The researchers reported that tomatoes possess some 35,000 genes arranged on 12 chromosomes. "For any characteristic of the tomato, whether it's taste, natural pest resistance or nutritional content, we've captured virtually all those genes," James Giovannoni, a scientist at the Boyce Thompson Institute for Plant Research, told Phys.org

New method to design better greenhouses

Doctorate student Bram Vanthoor of Wageningen UR Glastuinbouw has developed a method of calculation to design greenhouses better suited to local circumstances. The method has been tested for the Netherlands and Spain. During the tests two different greenhouse designs were built fully in line with the local situation. The method offers the possibility to optimise greenhouse building worldwide. Vanthoor will defend his thesis on Friday 17th of June.
Arch greenhouses, parral greenhouses, Venlo greenhouses and wide roof greenhouses, the variation worldwide is enormous. When designing a greenhouse one must also choose between a large number of different construction elements, such as e.g. roofing materials, heating and cooling systems. Which kind of greenhouse the grower chooses and how the greenhouse is being fitted is amongst other things, dependent upon the outside climate, economic factors, legal issues, social circumstances and the presence of sources, such as water, energy and CO2. The choice in favour of one possibility very often has a direct influence on the other elements and also depends on the plants to be cultivated in the greenhouse. This makes it very difficult to optimize the design process.

Optimization design
Bram Vanthoor developed a design method, which dependent on the local climate and economic conditions, designs a greenhouse which supplies the maximum financial result. The method always includes local circumstances and takes eight design elements into consideration, namely greenhouse construction, roofing material, outside awnings, chalk materials, energy screen, heating system, cooling system and CO2 quantity dosing system.

The design method is based on three models, namely one greenhouse climate model, one plant model and an economic model. These models calculate, dependent on the variables supplied, the financial result. After that an optimalisation-algorithm adjusts the design step by step. In this way the financial result is maximised finally and the best greenhouse found.

The design method has been tested in Spain and in the Netherlands. The model was designed quite differently for both locations, but with realistic proposals for the most successful greenhouse in both instances. The Spanish greenhouse had a larger ventilation area and was specially built to prevent high temperatures, whilst in the colder Netherlands a higher working capacity and an energy screen were fitted. It became clear at both locations, that the economic performance of the greenhouse improves by a high percentage of light passing through and that an outside screen, geothermic heating and mechanical cooling make the result worse.

Perspective of the method
The method has in first instance been developed for tomatoes. Adjustment for other
plants is possible. The design method of the greenhouse can assist in optimizing the cultivation of plants in greenhouse further. It is also possible to establish the best location to build new greenhouse with the new approach and the results of the economic changes on the cultivation can be predicted. Bram Vanthoor in the meantime lives and works as a business developer for a horticultural supplier in Mexico. The acquired knowledge is used there to adapt greenhouse to the local conditons.

Cucumber nutrition facts

BY: A M Awan

Ever wonder how to beat the scorching summer heat? Remember humble crunchy cucumber! This wonderful, low calorie vegetable indeed has more nutrients to offer than just water and electrolytes.
The vegetable is one of the oldest cultivated crops and believed to be originating in the northern plains of Indian subcontinent. The plant is a creeper (vine) like other members of Cucurbita family, for example, gourds,squashes,melons,zucchini, etc.
Botanically; it belongs to the Cucurbitaceaefamily; and is known scientifically as Cucumis sativus.
Cucumber is easy to grow. Varieties, varying in size, shape, and color, are cultivated all around the world. In general, the fruit features dark-green skin, crispy moisture rich flesh, and small edible seeds concentrated at its core.
As in other squash members, cucumbers too are best-harvested young, tender and just short of reaching maturity, at the stage when they taste sweet, have crunchy texture, and unique flavor. If left uninterrupted, the fruit continues to grow in size, its skin becomes tougher and turns yellow, and seeds become hard and inedible. Fresh cucumbers are available throughout the season and can be eaten raw as is or in vegetable salads or juicing.
Armenian cucumbers (Cucumis melo var. flexuosus) are long, crispy, and thin-ribbed, curved, and have light green color. Although grouped botanically in the melon family, they appear and taste just like cucumbers.

Miniature varieties such as gherkins, American-dills, and French-cornichonsare very small indeed and usually preferred in pickling.

Health benefits of Cucumber

• It is one of the very low calorie vegetables; provide just 15 calories per 100 g. It contains no saturated fats or cholesterol. Cucumber peel is a good source of dietary fiber that helps reduce constipation, and offer some protection against colon cancers by eliminating toxic compounds from the gut.
• 
  It is a very good source of potassium, an important intracellular electrolyte. 100 g of cucumber provides 147 mg of potassium but only 2 mg of sodium. Potassium is a heart friendly electrolyte helps bring a reduction in total blood pressure and heart rates by countering effects of sodium.
• Cucumbers contains unique anti-oxidants in moderate ratios such as ß-caroteneand α-carotene, vitamin-C, vitamin-A,zea-xanthinand lutein. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes. Their total antioxidant strength, measured in terms of oxygen radical absorbance capacity (ORAC value), is 214 µmol TE/100 g.
• Cucumbers have mild diuretic property, which perhaps attributed to their free-water, and potassium and low sodium content. This helps in checking weight gain and high blood pressure.
• They surprisingly have a high amount of vitamin K, provides about 17 µg of this vitamin per 100 g. Vitamin-K has been found to have a potential role in bone strength by promoting osteotrophic (bone mass building) activity. It also has established role in the treatment of Alzheimer's disease patients by limiting neuronal damage in their brain.

1.Quick pick me-up - Cucumbers are a good source of B vitamins. Put down your sodas and coffee and eat a cucumber slice.

2. Rehydrates body and replenishes daily vitamins - Cucumbers are 95 percent water, keeping the body hydrated while helping the body eliminate toxins. Cucumbers have most of the vitamins the body needs in a single day. Don't forget to leave the skin on because the skin contains a good amount of vitamin C, about 10 percent of the daily-recommended allowance.

3. Skin and hair care - If you don't like to eat the skin, it can be used for skin irritations and sunburns as aloe would be used. Place a slice over puffy eyes and its anti-inflammatory properties help reduce puffiness. The silicon and sulfur in cucumbers help to stimulate hair growth.

4. Fight cancers - Cucumber are known to contain lariciresinol, pinoresinol, and secoisolariciresinol. These three lignans have a strong history of research in connection with reduced risk of several cancer types, including breast cancer, ovarian cancer, uterine cancer and prostate cancer.

5. Home care - Eliminates a foggy mirror. Before taking a shower, rub a cucumber slice along a mirror and it will eliminate the mirror fogging up. Instead of WD40, take a cucumber slice and rub it along a squeaky hinge and your door will stop squeaking.

6. Relieves bad breath - Take a slice of cucumber and press it to the roof of your mouth with your tongue for 30 seconds, the phytochemcials will kill the bacteria in your mouth responsible for causing bad breath.

7. Hangover cure - To avoid a morning hangover or headache; eat a few cucumber slices before going to bed. Cucumbers contain enough sugar, B vitamins and electrolytes to replenish many essential nutrients, reducing the intensity of both hangover and headache.

8. Aids in weight loss and digestion - Due to its low calorie and high water content, cucumber is an ideal diet for people who are looking for weight loss. The high water content and dietary fiber in cucumbers are very effective in ridding the body of toxins from the digestive system, aiding digestion. Daily consumption of cucumbers can be regarded as a remedy for chronic constipation.

9. Cures diabetes, reduces cholesterol and controls blood pressure - Cucumber juice contains a hormone which is needed by the cells of the pancreas for producing insulin which has been found to be beneficial to diabetic patients. Researchers found that a compound called sterols in cucumbers may help reduce cholesterol levels. Cucumbers contain a lot of potassium, magnesium and fiber. These work effectively for regulating blood pressure. This makes cucumbers good for treating both low blood pressure and high blood pressure.

10. Promotes joint health, relieves gout and arthritis pain -Cucumber is an excellent source of silica, which is known to help promotes joint health by strengthening the connective tissues. They are also rich in vitamin A, B1, B6, C & D, Folate, Calcium, Magnesium, and Potassium. When mixed with carrot juice, they can relieve gout and arthritis pain by lowering the uric acid levels

Robot learns to pick the sweetest strawberries in UK

Richard Dudley imagines a world where strawberries grow in perfect rows and every day a robot army "tastes" their colors before harvesting the ripe ones. The research scientist at the United Kingdom’s National Physical Laboratory is building a robot that uses multiple wavelengths of electromagnetic radiation to identify the sweetest, ripest fruit — then plucks it from the vine.

Strawberries are a fickle, high-value crop, and harvesting them is costly. Lucky for Dudley, though, they can be grown in a variety of robot-picking-friendly ways. He isn’t first to the droid-worker game — organizations in Spain, Japan, and the United States have produced tractors with gripping arms — but all of them have the same disadvantage: They have trouble differentiating between the leaves and the fruit. Dudley’s ‘bot solves this problem by analyzing the plants with a combo of micro-, radio, terahertz, and far-infrared waves.

So far, microwaves work best for strawberries. The waves find the fruit and measure its water content — an indicator of ripeness — effectively taking a taste test. "With microwaves, leaves are actually quite transparent," Dudley says. He describes it as a safe "x-ray eye," since actual x-rays would irradiate the crop. He hopes to work with a company that builds robotic arms to make the tech a commercial reality for farmers within a year.

Pomegranate nutrition facts

Pomegranate is among the most popular, nutritionally rich fruit with unique flavor, taste, and heath promoting characteristics. Along with berries, and some tropical exotics such as mango, it too has novel qualities of functional foods often called as “super fruits.”

Botanically, it is a small size fruit-bearing deciduous tree belonging within the Lythraceaefamily, of genus: Punica. The fruit is thought to originate in the Sub-Himalayan range of North India. Scientific name: Punica granatum.
The tree grows to about five and eight meters tall. It is cultivated at a commercial scale in vast regions across Indian sub-continent, Iran, Caucuses and Mediterranean regions for its fruits. Completely grown-up tree bears numerous spherical, bright red, purple, or orange-yellow colored fruits depending on the cultivar types. Each fruit measures about 6-10 cm in diameter and weighs about 200 gm. Its outer skin or rind is tough and features leathery texture.
Interior of the fruit is separated by white, thin, spongy, membranous, bitter tissue into compartments. Such sections, packed as sacs, filled with tiny edible sweet, juicy, pink pulp encasing around a single, angular, soft or hard (in over-mature fruits) seed.
Pomegranate is one of the most extensively cultivated fruits for food, juice, flavor, and color, making it a common ingredient in new functional foods often called “super fruits."

Health benefits of Pomegranate

• The fruit is moderate in calories; 100 g provides 83 calories, slightly more than that in theapples. It contains no cholesterol or saturated fats.
• It is rich source of soluble and insoluble dietary fibers, providing about 4 g per 100 g (about 12% of RDA), which aid in smooth digestive and bowel movements. The fruit is suggested by nutritionists in the diet for weight reduction and cholesterol controlling programs. Regular inclusion of fruits in the diets boosts immunity, improves circulation, and offers protection from cancers.
• Punicalaginis a polyphenolic anti-oxidant compound found abundantly in the pomegranate juice. Studies suggest that punicalagin and tannins are effective in reducing heart-disease risk factors by scavenging harmful free radicals from the body.
• Total antioxidant strength of pomegranate fruit measured in terms of its oxygen radical absorbance capacity (ORAC) is 2341 µmol TE/100 g.
• The fruit is an also good source of antioxidant vitamin-C, provides about 17% per 100 g of daily requirement. Consumption of fruits rich in vitamin C helps the body develop resistance against infectious agents by boosting immunity.
• Regular consumption of pomegranate has also been found to be effective against prostate cancer, benign prostatic hyperplasia (BPH), diabetes, and lymphoma.
• 
  Further, it is an also good source of many vital B-complex groups of vitamins such as pantothenic acid (vitamin B-5), folates, pyridoxine and vitamin K, and minerals like calcium, copper, potassium, and manganese.

Banana fruit nutrition facts

Go for banana fruit, nature's own energy-rich food that comes in a safety envelope! Fresh, delicious bananas are available year around and in fact, one of the cheapest fruits. Botanically, the fruit belongs to the family of Musaceae.Commercially, it is one of the widely cultivated crops in the tropical and subtropical zones.
Scientific name: Musa acuminata colla.

Banana is a perennial herbaceous plant that develops from the underground rhizome. It flourishes well under tropical moisture-rich, humid low-lying farmlands.
In fact, the whole plant is a false stem (pseudostem), consisting of broad leaves along with their petioles overlapping around each other in a circular fashion standing up to 2 to 6 meters tall from the ground surface depending upon the cultivar types. At maturity, the rhizome gives rise to flower (inflorescence) that is carried up on a long smooth un-branched stem through the centre of the pseudo-stem emerging out at the top in the centre of the leaf cluster. The flower subsequently develops to hanging bunch consisting of 3 to 20 hands (tiers), each with at least 5-10 fingers (fruits) in each hand (tier). Banana plant or plantain bears hanging clusters of fruits as a bunch. Fruits are arranged in tiers, with 6-20 fruits in each tier.

Health benefits of banana fruit

• Banana fruit is one of the high calorie tropical fruits. 100 g of fruit provides 90 calories. Besides, it contains good amounts of health benefiting anti-oxidants, minerals, and vitamins.
• Banana pulp is composed of soft, easily digestible flesh with simple sugars like fructose and sucrose that when eaten replenishes energy and revitalizes the body instantly; thus, for these qualities, bananas are being used by athletes to get instant energy and as supplement food in the treatment plan for underweight children.
• The fruit contains a good amount of soluble dietary fiber (7% of DRA per 100 g) that helps normal bowel movements; thereby reducing constipation problems.
• It contains health promoting flavonoid poly-phenolic antioxidants such aslutein, zea-xanthin, ß and α-carotenes in small amounts. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.
• It is also a very good source of vitamin-B6(pyridoxine), provides about 28% of daily-recommended allowance. Pyridoxine is an important B-complex vitamin that has a beneficial role for the treatment of neuritis, and anemia. Further, it helps decrease homocystine (one of the causative factors in coronary artery disease (CHD) and stroke episodes) levels within the body.
• The fruit is an also moderate source of vitamin-C (about 8.7 mg per 100g). Consumption of foods rich in vitamin-C helps the body develop resistance against infectious agents and scavenge harmful oxygen-free radicals.
• Fresh bananas provide adequate levels of minerals like copper, magnesium, and manganese. Magnesium is essential for bone strengthening and has a cardiac-protective role as well. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase. Copper is required in the production of red blood cells.
• Fresh banana is a very rich source of potassium. 100 g fruit provides 358 mg potassium. Potassium is an important component of cell and body fluids that helps control heart rate and blood pressure, countering bad effects of sodium.

Health benefits of Persimmon (Japani Phal)

 

By Mohammed Rashid, Qarshi industries Pakistan

Diospyros kaki is the botanical name of Persimmon or Japani Phal. Diospyros comes from the ancient Greek words, this means more or less "divine fruit", though its literal meaning is more like "Wheat of Zeus".

This species, native to China, is deciduous, with broad, stiff leaves. Cultivation of the fruit extended to East Asia, California, Europe and Brazil.

Its trees have been classified broadly into two general categories: those that bear "astringent fruit" (whilst unripe) and those that bear "non-astringent" fruits. An astringent cultivar, which is commonly cultivated in Japan known as “Hachiya,” is high in tannins and must be allowed to ripen fully until it attains jelly-soft consistency before fit to eat. A non-astringent persimmon, on the other hand, contains less tannin and can be eaten while it is crispy as in apples. Astringency can be removed by treating the fruit with carbon dioxide or alcohol.

Health benefits:

1. They are also a very good source of vitamin-C. Regular consumption of foods rich in vitamin C helps the body develop resistance against infectious agents and scavenge harmful, pro-inflammatory free radicals.

2. The fruit is good in many valuable B-complex vitamins such as folic acid, pyridoxine (vitamin B-6), thiamin...etc. These vitamins act as co-factors for numerous metabolic enzymatic functions in the body.

3. Persimmons are replete with many phyto-nutrients flavonoid poly-phenolic anti-oxidants. Catechins and gallocatechins as well as important anti-tumor compound betulinic acid contained in this fruit is said to be highly beneficial for health. Catechins are known to have anti-infective, anti-inflammatory and anti-hemorrhagic properties.

4. Fresh persimmon fruits contain healthy amounts of minerals like potassium, manganese, copper and phosphorus. These minerals are believed to be powerful free radical scavengers and boost the production of blood cells.

Ginger Cultivation Basics

Ginger is an important spice crop of the world .Its scientific name is Zingiber officinale.Its a valuable cash crop and plays an important role in aurvedic medicines in India .It has been used for cleaning body through perspiration,to calm down nausea,and to stimulate the appetite.Ginger tea is used as carminative and in the symptomatic treatment of colds.Ginger contains gingerol, an oleo resin that accounts for the characteristic aroma and therapeutic properties.Components of gingerol posses beneficial properties for the treatment of poor digestion,heart burn,vomiting and preventing motion sickness.

 

Climate and soil

Ginger requires tropical,subtropical and humid climate for its commercial production.It can be successfully grown to an altitude of 1500mt.A well distributed rainfall during growing season and dry season during the land preparation as well as before harvesting is required for good growth and

yield of the crop. Dry weather with a temperature range of 28-30 degree Centigrade for about a month before harvesting is ideal . High humidity throughout the crop period is necessary. Ginger prefers good garden soil, rich in humus, light, loose, friable, well drained and of at least 30 cm depth. Rhizome growth is better on slightly acidic soil.

Varieties

Most promising varieties of ginger are Himgiri,Varad,surbhi,suruchi,Ernas,Nadia,Maran,Rio de jenerio and China.

Planting

In northern India, planting of Ginger is done on the onset of monsoon. In Eastern India planting is done in the month of march.The method of land preparation depends on the soil and climatic conditions.Usually beds of 1.0 mt width ,15 cm height, and 6-7 metre in length with 30 cm wide channels between beds are made. Ginger is universally propagated from cutting of Rhizome known as bits. A direct relationship has been established between size of planting material and final yield. Bits should be 3-5cm in the length, 15- 20gm in weight and at least one sound bud .A seed rate of 15-20 Quintal per hectare is considered to be optimum for planting. Before planting bits should be treated with fungicide like carbendazim and mancozeb by dissolving the 30 gm of powder in 15 litres of water as a safeguard against soft rot and to induce early sprouting.The spacing for planting of the ginger should be kept 25-45 cm between rows and 15-20 cm between plants.

Manures and Fertilizers

Well rotten FYM or compost at the rate of 25-30 ton/hectare should be applied at the time of planting. The amount of inorganic fertilizer depend upon the fertility of the soil and organic manure used. It ranges between 100-120 kg nitrogen, 75-80 kg of phosphorus and 100 -120 kg of Murat of potash.It is advisable to add 20-25 kg of elemental sulphur at the time of land preparation to correct the deficiency of sulphur which is increasing in Indian soils. Half of nitrogen and entire quantity of phosphorus and Murat of potash should be given as basal.Rest of the nitrogen should be split in two doses as top dressing at the 45 and 90 days after planting.

Shade and mulching

One row of maize in every inter row space of ginger with maintenance of 100% maize population and application of additional fertilizer to maize additional yield of ginger can beobtained. Mulching is essential as it enhances sprouting ,increase infiltration and organic matter .

First mulching should be done at the time of planting with quick rotting green leaves at the rate of 10-12 t/hectare or with dry leaves at the rate 5-6 t/hectare.

Water management

The crop raised in the month of April-May needs 2-4 initial watering at an interval of 7 days depending upon the soil types. After this the crop receives monsoon rain and comes up well till end of September . Subsequently the crop has to be given watering commencing from middle of October and the end of December at 15 days intervals. In ginger cultivation sprouting, rhizome initiation and rhizome development are critical stages of irrigation.

Weed management

Two weeding are generally given to the ginger crop.First weeding should be done just before the second mulching. It is repeated depending on the intensity of the weed growth or at an interval of 45-60 days. During hoeing , every care should be taken so that the rhizomes should not be disturbed, injured or exposed.

Plant Protection

To control shoot borer and leaf roller the spray of indoxacarb @ of 10 ml per 15 litre of water or novaluron@ of 10 ml per 15 litre of water is very effective if sprayed at 15 days interval. Rhizome scale insects destroys rhizome and it can be controlled by dipping the seed rhizome in quinalphos by dissolving 1 ml in 1 litre of water .To avoid rhizome rot , good drainage and treatment of the seed rhizome with dissolving 3 gm of combination of carbendazim and mancozeb ( readily available in the market) in 1 litre of water for nearly 30 minutes, before storage should be done. Bacterial wilt which causes milky ooze as gentle pressing of rhizomes and can be effectively controlled by treating the seed rhizome with dissolving 2 gm of streptocycln in 1 litre of water for 30 minutes.

Harvesting and yield

For fresh Ginger, the crop should be harvested before attaining the full maturity means when rhizomes are still tender, low in pungency and fiber content, usually from fifth month onwards after planting. Harvesting for the preserved ginger should be done after 5-7 months of planting while harvest for dried spices and oil is best at full maturity. i.e between 8-9 months after planting when leaves start yellowing. Rhizomes to be used for planting material should be harvested until the leaves become completely dry. After digging the rhizomes should be treated with fungicide like mancozeb @3-4 gm per litre of water , dried in shade , and stored in pits covered with 20 cm layer of sand alternating every 30 cm layer of rhizomes. These pits should be dug under a thatched roof to protect the rhizomes from rain, water and direct sun. Average yield varies from 12-15 tons per hectare. However recovery of dry ginger varies from 20-22%.

Washing and drying

After harvest, the fibrous roots attached to the rhizome should be trimmed off and soil is removed by washing. Rhizomes should be soaked in water overnight and then cleaned. The skin can be removed by scrapping with the correct instrument. Peeling or scraping reduces, drying time, thus minimizes mold growth and fermentation. However scraping process tends to remove some of the oils constituents which are more concentrated in the peel. By removing the outside Corky skin the fiber content also decreases. After scrapping, the rhizomes should be sun dried for a week with frequent turning and well rubbed by hand to remove the outer skin. This is called as the unbleached ginger . The peeled rhizomes should be repeatedly immersed in 2% lime solution for 6 hours and allowed to dry in the sun for 10 days while rhizome receive a uniform coating of lime and moisture content should be 8-10%. This is called as bleached ginger which has improved appearance with light bright colour.
