  • Despite this popularity, gardeners always find it challenging to grow such plan as well as determine what the time of watermelon last on the vine and harvested. (gardenercorner.com)
  • fruit
  • It is grown in tropical and subtropical areas worldwide for its large edible fruit, also known as a watermelon, which is a special kind of berry with a hard rind and no internal division, botanically called a pepo. (wikipedia.org)
  • Major pests of the watermelon include aphids, fruit flies and root-knot nematodes. (wikipedia.org)
  • While watermelon might not rank very high on your personal list of foods with great diversity, this fruit is far more diverse than many people suspect. (whfoods.com)
  • However, you'll typically want to make sure that a watermelon is sufficiently ripe before purchasing it in order to receive great texture and flavor from this fruit. (whfoods.com)
  • Additionally, other wild species have bitter fruit containing cucurbitacin. (wikipedia.org)
  • The generic name Citrullus is the diminutive of Citrus , perhaps referring to the spherical fruit. (worldwidefruits.com)
  • It is grown for its edible fruit, also known as a watermelon , which is a special kind of berry botanically called a pepo . (worldwidefruits.com)
  • The actual fruit of this plant resembles the more modern, domesticated watermelons, except that it is smaller and more spheroid. (wikipedia.org)
  • plants
  • Watermelons are tropical or subtropical plants and need temperatures higher than about 25 °C (77 °F) to thrive. (wikipedia.org)
  • Most species have separate male and female flowers on the same plant, and are insect-pollinated out-crossers, preferring pollination via other plants. (nativeseeds.org)
  • stems
  • The watermelon is a large annual plant with long, weak, trailing or climbing stems which are five-angled (five-sided) and up to 3 m (10 ft) long. (wikipedia.org)
  • It has evolved independently in several plant families, using many different climbing methods such as: twining their stems around a support (e.g., morning glories, Ipomoea species). (wikipedia.org)
  • crop
  • The dominant species of ant in India and much of southeastern Asia is Camponotus compressus, and the presence of ants on the crop plant has a deterrent effect on R. foveicollis. (wikipedia.org)
  • cultivars
  • and 4) to screen the U.S.D.A. watermelon germplasm collection along with available watermelon cultivars to identify additional sources of resistance to ZYMV. (ncsu.edu)
  • A total of 1275 plant introduction accessions and 44 watermelon cultivars were screened for PRSV-W resistance. (ncsu.edu)
  • The USDA germplasm collection of 1613 introduction accessions, as well as 41 watermelon cultivars, was screened for resistance to the Florida strain of Zucchini yellow mosaic virus (ZYMV-FL). (ncsu.edu)
  • resistance
  • Seedless watermelons were initially developed in 1939 by Japanese scientists who were able to create seedless triploid hybrids which remained rare initially because they did not have sufficient disease resistance. (wikipedia.org)
  • Watermelon has not been screened extensively for resistance to PRSV-W. Although there is a resistance source for ZYMV resistance, the identification of additional sources of resistance to ZYMV would be highly desirable since the initial sources of resistance are temperature dependent, or not resistant to some of the more severe strains of the virus. (ncsu.edu)
  • Therefore, the gene symbol 'prv' is proposed for PRSV-W resistance in PI 244017, PI 244019, and PI 485583 in watermelon. (ncsu.edu)
  • Bailey
  • Although this error only occurred in 1930 (Bailey, Gentes Herbarum 2: 180-186), it has been perpetuated in hundreds of papers on the watermelon. (wikipedia.org)
  • Foods
  • While both foods are top-rated sources of this carotenoid, red-fleshed watermelons typically average between 4-5 milligrams of lycopene in every 100 grams (approximately two-thirds cup in volume), while red tomatoes usually contain about 3-4 milligrams per 100 grams (approximately 1/2 cup in volume).

  • molecular
  • Before modern DNA-molecular classifications, some Cucurbitales species were assigned to orders as diverse as Ranunculales, Malpighiales, Violales, and Rafflesiales. (wikipedia.org)
  • wild
  • Still and all, for many thousands of years, hundreds of wild and (in time) cultivated native species complemented each other to comprise the core of the continental food supply. (nap.edu)
