A screening method for storage-resistant wheat seeds

Abstract

The invention discloses a method for screening wheat seeds with storage resistance, which belongs to the technical field of seed storage and comprises the following steps: randomly selecting 100 plump and vigorous wheat seeds, measuring the water content of the seeds with a moisture meter, and weighing the seeds , record the water content and weight data; put it in a petri dish for germination treatment, observe the dynamic changes of the seeds after absorbing water, stop the germination treatment and record the time when the seed imbibition stage is completed and reach the bubbling state; then weigh the bubbling seeds Weight and measure the water content of the bubbling seeds with a moisture meter, and record the data of the weight and water content of the bubbling seeds; the weight change of the seeds before and after water absorption and the change of dry matter are combined with the time required for bubbling to calculate and evaluate the data. The invention conducts statistical analysis on the storability of the seeds by bubbling the water collection rate value of the seeds, the seed dry matter loss rate value and the time required for bubbling, so as to identify and evaluate the storability of the wheat seeds.

Description

technical field [0001] The invention relates to the technical field of wheat seed storage, in particular to a screening method for storage-resistant wheat seeds. Background technique [0002] Wheat is the main grain crop in my country, and its annual total output accounts for about 22% of the total grain output. Wheat can produce a variety of foods, and is one of the main sources of nutrition for human protein, calories and food. The national per capita wheat ration consumption accounts for more than 95% of the total wheat consumption. Wheat has the characteristics of thin seed coat, loose tissue structure, good storage resistance, and is an important reserve grain. Storage is the last link in the wheat production process before the value is reflected, and it is related to whether the value of wheat can be fully exerted. According to incomplete statistics, the annual loss of wheat due to storage pests, heat and mildew, and self-aging during storage accounts for about 6.62%...

AI Technical Summary

Problems solved by technology

However, deep life activities after bubbling will cause a large loss of dry matter, serious deterioration of quality, loss of seed and edible value, direct impact on market value, and heavy economic losses

[0007] In view of the fact that the existing technical solutions cannot fundamentally solve the mildew problem in the wheat seed storage process, in order to overcome its disadvantages, through the hydrophilic substances contained in different varieties of seeds and the differences in moisture absorption capacity and physiological metabolic activities of seeds, in Responses are different when subjected to the influence of temperature and humidity. For the first time, the value of water accumulation rate, dry matter loss rate and time required for bubbling seeds are included in the evaluation index of storability wheat varieties
