Problems solved by technology

During the sand storage period, the seeds often rot due to poor control of water or ventilation conditions, or poor control of the length of low-temperature stratification time, which affects the normal release of dormancy of the seeds, resulting in the inability of the seeds to germinate or the low germination rate after sowing. For the hybrid seeds recovered through hybridization, if the seed layering is not handled well and cannot germinate, it will affect the breeding work plan

Embodiment Construction

[0021] Seed germination rate is an important index for seed testing. It runs through the whole process of seed inspection, and mutually restricts and promotes each other with the links of seed production, processing, storage, and operation. Scientifically use the germination rate of seeds to judge the quality, authenticity and value of seeds. Doing a good job in the determination of seed germination rate has important practical significance and far-reaching historical significance for implementing the national seed industrialization project plan and promoting the integration of breeding, propagation, promotion and sales of improved seeds. By adopting the method of the invention, the germination rate of pear seeds can be quickly, easily and accurately measured, and the growth status of seedlings can be observed in time. The specific operation process is as follows:

[0022] 1 Seed collection: peel off the pericarp of the ripe fruit, wash and remove the pulp, leave the seeds c...

Abstract

The invention relates to a method for quickly breaking birchleaf pear seed dormancy, and belongs to the technical field of plant production. The method for quickly breaking the birchleaf pear seed dormancy mainly comprises the following steps of: 1) picking and washing seeds; 2) soaking the seeds into clear water and sterilizing the seeds; 3) treating the seeds with a chemical agent and cleaning the seeds; and 4) sowing the seeds. The birchleaf pear seeds treated by sodium nitroprusside (SNP) begin to sprout after being sown for 3 days and fully sprout about one week later, wherein the sprouting percentage reaches over 80 percent. The method has the advantages of simpleness, convenience, quickness, safety, and good application and popularization prospect.

Description

technical field [0001] The invention relates to a method for quickly breaking the dormancy of pear rootstock seeds, relates to the dormancy and germination of pear rootstock seeds, belongs to the technical field of plant production, and establishes a set of simple, convenient, fast and safe detection methods. Background technique [0002] The dormancy characteristic of pear seeds has brought a lot of inconvenience to agricultural and forestry production. It is of great practical significance to explore how to quickly, easily and safely release the dormancy of pear seeds. In production, in order to accelerate seed germination and increase seed germination rate, artificial methods are often used to break seed dormancy. Since the seed coat of pear seeds is thick, it can be treated by removing the seed coat, hydrogen peroxide or concentrated sulfuric acid to damage the seed coat, increase the air permeability and water permeability of the seed coat, and increase the germination ...
