Watermelon

Warm Season Fruits

Watermelon is a tender, warm-season fruits. Watermelons can be grown in all parts of the country, but the warmer temperatures and longer growing season of southern areas especially favor this vegetable. Gardeners in northern areas should choose early varieties and use transplants. Mulching with black plastic film also promotes earliness by warming the soil beneath the plastic. Floating row covers moderate temperatures around the young plants, providing some frost protection in unseasonable cold spells.
Seedless watermelons are self-sterile hybrids that develop normal-looking fruits but no fully developed seeds. The seeds for growing them are produced by crossing a normal diploid watermelon with one that has been changed genetically into the tetraploid state. The seeds from this cross produce plants that, when pollinated by normal plants, produce seedless melons.

In seedless watermelons (genetic triploids), rudimentary seed structures form but remain small, soft, white, tasteless and undeveloped tiny seedcoats that are eaten virtually undetected along with the flesh of the melon. Seed production for these seedless types is an extremely labor intensive process that makes the seeds relatively expensive. Because germination of these types is often less vigorous than normal types, it is recommended that they be started in peat pots or other transplantable containers, where the germinating conditions can be closely controlled Once transplanted, cultivation is similar to that for regular watermelons.

For pollination necessary to set fruit, normal seed types must be interplanted with seedless melons. The pollinator should be distinct from the seedless cultivar in color, shape or type so that the seedless and seeded melons in the patch can be separated at harvest. Because seedless types do not put energy into seed production, the flesh is often sweeter than normal types and the vines are noticeably more vigorous as the season progresses.

Nutrition Value in Water Melon
Watermelons are low in calories and very nutritious. Watermelon is high in lycopene, second only to tomatoes. Recent research suggests that lycopene, a powerful antioxidant, is effective in preventing some forms of cancer and cardiovascular disease. According to research conducted at the University of North Carolina at Chapel Hill, men who consumed a lycopene-rich diet were half as likely to suffer a heart attack as those who had little or no lycopene in their diets.

Watermelon is also high in Vitamin C and Vitamin A, in the form of disease fighting beta-carotene. Research also suggests that the red pigmented foods provide this protection. Lycopene and beta-carotene work in conjunction with other plant chemicals not found in vitamin/mineral supplements. Potassium is also available, which is believed to help control blood pressure and possibly prevent strokes.
