Method for promoting rapid and efficient germination of Chinese cherry seeds

Abstract

The embodiment of the invention provides a method for promoting rapid and efficient germination of Chinese cherry seeds, which relates to the field of seed processing, and is capable of increasing the germination rate of the Chinese cherry seeds, and shortening the breeding or seedling time of the cherry. The method comprises the steps of after cherry is in full maturity, collecting fruits and removing surface pulp, washing by normal-temperature water, washing, airing kernels to obtain clean kernels, and arranging the clean kernels into a refrigerator at 4 DEG C for later use; removing the hulls of the clean kernels, or removing the hulls and then stripping seed coats coating plumular axes, then uniformly arranging the clean kernels in a container paved with two layers of wet towels, then covering two layers of wet towels with the same humidity, inducing for 5-7 days in an environment at 0-4 DEG C, taking out seeds and sowing in a seedbed according to plant and row spacing being 2*3cm, culturing for 3-6 days at normal temperature, and germinating; when the unfolded seedlings of the main leaves of seedlings are 3-5cm high, spraying 0.2% monopotassium phosphate solution on leaf surfaces every seven days, and planting the seedlings in a field when the seedlings grow to be more than 15cm high.

Description

technical field [0001] The invention relates to the field of seed treatment, in particular to a method for promoting rapid and efficient germination and seedling formation of Chinese cherry seeds. Background technique [0002] Chinese cherries are the earliest fruit on the market in spring, and they play a special role in regulating the market supply of fresh fruit in the off-season and meeting people's daily needs. Its fruit is bright in color, crystal clear and beautiful, rich in nutrition, good in appearance and internal quality, known as "treasure among fruits" and known as "the first branch of spring fruit". [0003] Drupe seeds have a long dormancy period after harvesting, and can only germinate and grow after the seeds are released from dormancy. Due to the short fruit development period of Chinese cherry, it only takes about 40 days from flowering to fruit maturity, and the seed germination rate is relatively low due to insufficient development of the seed embryo, a...

Problems solved by technology

However, the seed treatment procedure is complex, time-consuming and labor-intensive, and the wet storage period coincides with high temperature and high humidity in summer, so the seeds are prone to mold and deterioration, and the cycle for hybrid breeding is also longer

The gibberellin treatment method is a method for treating seeds with a certain concentration of gibberellin for different types of cherries to break dormancy and promote germination, but this method needs to explore different concentrations for different types of cherries, and the germination and seedling rates are also high relatively low cost

[0005] Therefore, although predecessors have made some progress in breaking the dormancy of cherry seeds, these techniques are time-consuming, laborious, difficult to achieve the desired effect, and more importantly, the germination rate is also low
