Abstract

The invention provides a novel layering method for breaking dormancy of arbor seeds, and belongs to the technical field of plant seed cultivation. The invention provides a novel stratification method adopting low-temperature water stratification treatment. The method is to place arbor seeds in sterile water and perform stratification treatment at a low temperature of 2-5° C. for 53-81 days. The low-temperature water stratification treatment method provided by the invention can effectively break the deep dormancy characteristics of arbor seeds, and significantly improve the germination characteristics of the seeds. The seeds of Junqianzi and ornamental crabapple seeds are used as test materials for low-temperature water stratification treatment, and the germination rate and germination rate The potential average is higher than the traditional low-temperature sand stratification method, and the shortest stratification time for low-temperature water stratification treatment is only 53 days, which is 7 days shorter than the 60-day period for sand stratification treatment, which can effectively replace the traditional Low-temperature sand storage layered, and has the characteristics of simple, safe and hygienic.

Description

technical field

[0001] The invention belongs to the technical field of plant seed cultivation, and in particular relates to a novel layering method for breaking dormancy of arbor seeds. Background technique

[0002] Seed germination is the basis of crop growth, an important link and turning point in the life cycle of seed plants, the starting point for the growth and development of higher plants, and an important characteristic for plants to adapt to environmental changes to maintain their own reproduction. Seed germination is directly related to ecological processes such as species reproduction, population maintenance, expansion and recovery, and also directly affects the distribution, dynamics and diversity of vegetation. However, due to the limitation of the seed coat and the influence of the existing state of internal nutrients, plant seeds generally have physiological dormancy.

[0003] Seed dormancy refers to the phenomenon that mature and viable seeds cannot germinat...
