Seedless watermelon In botany and horticulture , parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules , which makes the fruit seedless. The phenomenon has been observed since ancient times [ 1 ] but was first scientifically described by German botanist Fritz Noll in 1902.
By contrast, seedless watermelons are grown from seeds. These seeds are produced by crossing diploid and tetraploid lines of watermelon, with the resulting seeds producing sterile triploid plants. Fruit development is triggered by pollination, so these plants must be grown alongside a diploid strain to provide pollen.
Watermelon seeds were found in the Dead Sea region at the ancient settlements of Bab edh-Dhra and Tel Arad. [21] Many 5000-year-old wild watermelon seeds (C. lanatus) were discovered at Uan Muhuggiag, a prehistoric archaeological site located in southwestern Libya. This archaeobotanical discovery may support the possibility that the plant was ...
Most commercial seedless grapes are sprayed with gibberellin to increase the size of the fruit and also to make the fruit clusters less tightly packed. A new cultivar, 'Melissa', has naturally larger fruit so does not require gibberellin sprays. [2] Grape breeders have developed some new seedless grape cultivars by using the embryo rescue ...
Articles relating to the watermelon (Citrullus lanatus), a flowering plant species of the Cucurbitaceae family and the name of its edible fruit. A scrambling and trailing vine -like plant, it is a highly cultivated fruit worldwide, with more than 1,000 varieties .
Most instances of autopolyploidy result from the fusion of unreduced (2n) gametes, which results in either triploid (n + 2n = 3n) or tetraploid (2n + 2n = 4n) offspring. [21] Triploid offspring are typically sterile (as in the phenomenon of triploid block ), but in some cases they may produce high proportions of unreduced gametes and thus aid ...
Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [46] Roblox operates annual Easter egg hunts [52] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...
