Chen Wen-yu was particularly interested in the theory of seedless watermelons proposed by the Japanese researcher Hitoshi Kihara [6] in 1951, according to which crossing a female tetraploid plant (itself the product of genetic manipulation) with diploid pollen creates a triploid plant that is sterile, but can produce seedless fruit if ...
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 is a sweet, commonly consumed fruit of summer, usually as fresh slices, diced in mixed fruit salads, or as juice. [53] [54] Watermelon juice can be blended with other fruit juices or made into wine. [55] The seeds have a nutty flavor and can be dried and roasted, or ground into flour. [9]
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.
An ounce of watermelon seeds also has four grams of carbohydrates and is comprised of over 25% fiber. Some of the best sources of nutrition come from the concentration of vitamins and minerals ...
In some situations, polyploid crops are preferred because they are sterile. For example, many seedless fruit varieties are seedless as a result of polyploidy. Such crops are propagated using asexual techniques, such as grafting. Polyploidy in crop plants is most commonly induced by treating seeds with the chemical colchicine.
This was in contradiction to the expectations of Michurin's theory. Yuan concluded, "I had learned some background of Mendel and Morgan's theory, and I knew from journal papers that it was proven by experiments and real agricultural applications, such as seedless watermelon. I desired to read more and learn more, but I can only do it secretly ...
