Problems solved by technology

[0003] However, due to the short development period and immature embryos of the early-maturing varieties of sweet cherry, after conventional cultivation (such as stratification treatment, low temperature treatment, etc.) , which severely restricts the cultivation of new early-maturing varieties of sweet cherry
[0004] CN105284234A discloses a method for improving the germination rate of sweet cherry seeds, but the method is only applicable to middle and late varieties of sweet cherry
Because the seeds of Chinese cherry are fully developed and have relatively strong germination ability, while the seeds of early-maturing European sweet cherry varieties are not fully developed and have weak germination ability, the germination rate of seeds has not been significantly improved after cultivation by this method

Embodiment 1

[0050] A kind of processing method of the seedling of high-efficiency sweet cherry early maturing variety and the method for sowing seedling in the same year, the specific steps are as follows:

[0051] (1) Seed selection: In late March, select the natural pollination sweet cherry early-maturing variety 'Zaodaguo' that has just matured in the greenhouse, take the fruit that is free from diseases and insect pests, peel off the sweet cherry pulp and seeds, put it into a clean beaker, and wash it with tap water Clean, remove the seeds floating on the water surface (aborted), and pour off the remaining water.

[0052] (2) Pretreatment of seeds: Take out the seeds that sink to the bottom of the water in step (1), smash the outer testa with a hammer, take out the seed kernels, put them in a triangular flask, rinse them with distilled water, and add distilled water to soak , the water surface is higher than the seeds, cover with a sealing film, and refrigerate at 2-6°C for 1 day to a...

Embodiment 2

[0060] A kind of processing method of the seedling of high-efficiency sweet cherry early maturing variety and the method for sowing seedling in the same year, the specific steps are as follows:

[0061] (1) Seed selection: On April 22, select the sweet cherry early-maturing variety 'Zaomilu' that has just matured in the greenhouse and naturally pollinated, take the fruit that is free from diseases and insect pests, peel off the sweet cherry pulp and seeds, put into a clean beaker, and use Wash with tap water, remove seeds floating on the water surface (aborted), and discard the remaining water.

[0062] The approval information of ‘Zaomilu’ is: the original code is ‘6-46’, Ji S-SV-CA-008-2018, Hebei Forest Variety Approval Committee 2019.1.9.

[0063] (2) Pretreatment of seeds: Take out the seeds that sink to the bottom of the water in step (1), smash the outer testa with a hammer, take out the seed kernels, put them in a triangular flask, rinse them with distilled water, and ...

Abstract

The invention belongs to the technical field of seed treatment and seedling cultivation, and particularly relates to a seed treatment method for an early-maturing sweet cherry variety and a method forplanting seedlings in that year. The seed treatment method for sweet cherries comprises the following step of treating seed embryos in a liquid culture manner, wherein liquid culture conditions are as follows: under a sealed condition, culture is performed for 5-7 days at the temperature of 2-6 DEG C; and a culture solution comprises the following components: an agar-free MS culture medium, 1.0 mg / L of 6-BA and 0.2 mg / L of IAA. The method is simple, efficient and suitable for large-group treatment, the germination rate of seeds of the early-maturing sweet cherry variety and the obtaining rateof offspring can be remarkably increased, and the method has higher practical value and is beneficial to application and popularization in breeding units; and meanwhile, the seed germination rate ofmedium and late maturing varieties of the sweet cherries can also be obviously improved by the method.

Description

technical field [0001] The invention belongs to the technical field of seed treatment and seedling cultivation, and in particular relates to a seed treatment method of an early-maturing sweet cherry variety and a method for seedling formation in the same year of sowing. Background technique [0002] Sweet cherry varieties can be divided into early-maturing varieties, mid-maturing varieties, and late-maturing varieties according to the maturity period. Among them, early-maturing varieties are favored by growers due to their early maturity and high price. It is the goal of breeders to breed early-maturing sweet cherry varieties with excellent comprehensive properties. The basic breeding procedure of new varieties of sweet cherry: using varieties with excellent comprehensive traits as parents, hybridization to obtain hybrid seeds or natural seedlings; sowing these seeds to obtain hybrid seedlings or seedlings; and then selecting better ones from them Variety: For the breeding ...
