Embodiment Construction

[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] 1) The seed germination test was carried out from June 2019 to April 2020. Taking the method of the present invention as an example, and using conventional after-ripening means as a comparative example, the effects obtained by the two methods are shown in Table 1 below:

[0017] Table 1

[0018]

[0019] It can be seen from the above examples and comparative examples that the method of the present invention can shorten the production cycle of Taibai Fritillaria, improve the breeding ...

Abstract

The invention discloses a method for accelerating after-ripening of fritillaria taipaiensis seeds. The method comprises the following steps that the fritillaria taipaiensis seeds, fine sand and vermiculite are laminated in a room after being uniformly mixed according to a ratio of 1 to 1 to 2, and the humidity of the mixed material is kept at 60%-70%; and lamination is continuously carried out 1-2 months, and when seed coats are expanded, germs grow to 2/3-3/4 of the length of endosperm and the germs are subjected to morphological after-ripening, low-temperature catalytic treatment is carried out until buds are about to grow and before the germs produce white buds, and sowing is started. According to the technical scheme, an improved seed treatment method is adopted, after-ripening and germ germination of the fritillaria taipaiensis seeds are accelerated by controlling the variety and proportional relation of a matrix, and combining a lamination container, lamination treatment conditions and a follow-up catalytic treatment means, the germination rate and the seedling uniformity are improved, time is saved, the production period is shortened, the efficiency is improved, the breeding limitation of fritillaria taipaiensis is broken through, and the method has high practical application significance.

Description

technical field [0001] The invention relates to the technical field of plant seed treatment, in particular to a method for accelerating post-ripening of Fritillaria taiba seeds. Background technique [0002] Fritillaria taipaiensis P.Y.Li is a perennial herb of the genus Fritillaria in the family Liliaceae. The main breeding method of Taibai Fritillaria production is seed sowing. The propagation material of Taibai Fritillaria is seed. The seeds of Taibai Fritillaria are embryo post-ripening types. During the post-ripening development of seeds, there are environmental conditions and low temperature requirements, so that the embryo can complete a series of growth and differentiation processes in terms of shape and structure. Under natural conditions, post-ripening development lasts for a long time, resulting in breeding difficulties such as long dormancy period, low germination rate, and irregular emergence of Fritillaria taibai. [0003] Therefore, how to provide a method f...
