Seedless watermelon pollination method

Abstract

The invention belongs to the technical field of cultivation of melons and particularly relates to a seedless watermelon pollination method which includes the following steps: (1) selecting wild watermelon as a grafting stock and seedless watermelon as a grafting scion; (2) among the grafted seedlings, retaining one wild watermelon vine and one seedless watermelon vine in one grafted seedling plant; (3) with an insect vector, collecting pollen of the wild watermelon and pollinating the pollen to the seedless watermelon in the same plant; (4) when the seedless watermelon on the grafted seedling plant is fruited after pollination, selecting 2-3 fruits on one plant, retaining the selected fruits and picking-off all fruits of the wild watermelon; and (5) after watermelon fixation, topping the vines of both of the seedless watermelon and the wild watermelon, wherein other cultivation technologies are same as common cultivation technologies. The seedless watermelon natural pollination and fruit-setting method can completely replace a conventional artificial pollination method, thereby reducing labor investment and reducing cost, and also is high in fruit setting rate, is strong in anti-aging capability of the plants, is increased in weight of single fruit, is increased in yield and is excellent in quality of the fruits.

Description

technical field [0001] The invention belongs to the technical field of melon cultivation, and in particular relates to a seedless watermelon pollination method. Background technique [0002] Ordinary watermelon is a diploid plant, that is, there are 2 sets of chromosomes (2N=22) in the body, and its seedlings are treated with colchicine to double the chromosomes of the diploid watermelon plant cells to become tetraploid (4N=44). The male and female flowers of the ploidy watermelon develop normally, can bloom and bear fruit normally, and the seeds can germinate and grow normally. Then use the tetraploid watermelon plant as the female parent (remove the flowers during flowering), and the diploid watermelon plant as the male parent (get the pollen of the male flower to confer on the tetraploid pistil) for hybridization, thereby obtaining triploid seeds. After the triploid watermelon seeds are sown and planted, the male flowers of the diploid watermelon (called watermelon with ...

Problems solved by technology

[0005] At present, the production of traditional seedless watermelons is obtained by artificial pollination with seeded watermelon male flowers. Since this method requires artificial pollination, the input labor is large, the production takes a lot of work, the pollination time is long, and the production cost is high. , the fruit setting rate, single fruit weight and yield per mu are not high, and the overall efficiency of seedless watermelon production is low
