Description

A special detection device for seed cold resistance

technical field

The invention belongs to the field of seed detection devices, in particular to a special detection device for seed cold resistance.

Background technique

my country is a country with a vast territory. Plants in the northern region often encounter low temperature and chilling damage during winter cultivation, resulting in reduced crop yield and quality. Breeding of low temperature resistant varieties is an effective way to solve this problem, and establishing a set of reasonable and credible The low temperature evaluation index is the premise of this work. Studies have shown that low temperature chilling injury can reduce the seed germination index, increase the seedling chilling injury index, reduce the leaf area of the plant, reduce the stem diameter and plant height, hinder the growth of the root system, stunt the development of flower organs, and reduce the yield. It can be seen that low temperature can cause damage to plant growth at different developmental stages.
