Abstract

The invention provides a seedless watermelon anti-dehiscence method. According to the anti-dehiscence method, after a seedless watermelon grows to a fruit swelling period, a seedless watermelon anti-dehiscence agent is sprayed. The anti-dehiscence agent is prepared from ammonium molybdate, pectin, xylanase, calcium superphosphate, serine protease, astragalus polysaccharide and water. By the adoption of the seedless watermelon anti-dehiscence method, the fruit dehiscence rate of the planted seedless watermelon is lowered to 3.07-9.39%o.

Description

technical field [0001] The invention relates to a method for preventing fruit from cracking, in particular to a method for preventing seedless watermelon from cracking. Background technique [0002] Seedless watermelons are triploid, and triploid watermelons cannot form seeds due to chromosomal disorder in triploid cells during meiosis. Generally speaking, the synthesis sites of auxin in plants are leaf primordia, young leaves and developing seeds, and there are enzyme systems related to auxin synthesis in these sites. Under the catalysis of various enzymes, tryptophan in plants undergoes amino conversion, decarboxylation and two oxidation steps, and finally becomes auxin (indole acetic acid). In addition to a small amount of auxin in the pollen of diploid watermelon, seedless watermelon also contains an enzyme system that converts tryptophan into auxin. When the diploid pollen germinates, the formed pollen tube extends into the ovary of the triploid plant and transfers th...
