Germination accelerating method of seedless watermelons

Abstract

The invention discloses a germination accelerating method of seedless watermelons. The germination accelerating method comprises the following steps: a, scalding seeds for 10min to 15min to eliminate impurities and empty seeds; b, immersing the seeds for 3h to 5h with a sterilization and disinfection solution; taking out the seeds and washing the seeds with clean water until no mucus is left on surfaces of the seeds of the seedless watermelons; c, putting the seeds immersed in step b into a container containing a seed immersing nutrient solution at 50 DEG C to 55 DEG C for 5h to 6h; irradiating with an ultraviolet lamp for 10min to 20min and continually immersing the seeds for 0.5h to 1h; taking out the seeds and washing the seeds with clean water; d, spin-drying the seeds of the seedless watermelons and taking out the seeds; airing or drying the seeds with hot air until the seeds are semi-dry; covering the seeds with a wet towel immersed with a germination accelerating agent; e, putting the covered seeds into a constant-temperature box; adjusting the temperature to be 25 DEG C to 35 DEG C and accelerating germination; when 85 percent to 95 percent of the seeds have white sprouts, mixing the seeds with tidal sand and sowing the seeds at a proper time. When the method provided by the invention is used for accelerating the germination, the seedless watermelons have a high sprouting ratio and low morbidity and the harvested seedless watermelons have good mouthfeel.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for accelerating germination of seedless watermelons. Background technique [0002] Seedless watermelon has no seeds, good quality, convenient eating, high yield and disease resistance, and storage and transportation resistance. It is very popular among producers, operators and consumers. The planting area is gradually expanding, and it is cultivated all over the country. The seedless watermelon cultivated in production is triploid, which is a generation of hybrid triploid seeds produced by crossing tetraploid watermelon as female parent and diploid watermelon as male parent. The seed coat of triploid seeds is thick and hard, the hilum is wide and hard, the degree of suberization is high, especially the beak is particularly thick, the mouth is tight, the embryo is not fully developed, the cotyledons are mostly irregularly bonded, and germination...
