Screening method of storage-tolerant wheat seeds

Abstract

The invention discloses a screening method of storage-tolerant wheat seeds, which belongs to the technical field of seed storage. The screening method of the storage-tolerant wheat seeds comprises thefollowing steps: randomly selecting 100 full and viable wheat seeds, measuring the moisture content of the seeds with a moisture meter and weighing the seed weight, and recording the moisture contentand weight data; placing the seeds in a culture dish for bud forcing treatment, observing the dynamic changes of the seeds after absorbing water, and stopping the bud forcing treatment and recordingthe time when the seeds reach a bubbling state after the swelling phase is completed; weighing the weight of the bubbling seeds again and measuring the water content of the bubbling seeds with the moisture meter, and recording the data of weight and water content of the bubbling seeds; and combining the weight changes of the seeds before and after absorbing the water and the changes of the dry matters with the time required for bubbling for data calculation and evaluation. According to the invention, the storage tolerance of the seeds is statistically analyzed through the bubbling seed water accumulation rate value, seed dry matter depletion rate value and bubbling time, thereby identifying and evaluating the storage tolerance 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
