[0003] Peanut germplasm storage methods are mainly divided into three methods, namely ultra-low temperature long-term storage, low-temperature medium-term storage and normal temperature short-term storage, ultra-low temperature long-term storage and low-temperature medium-term storage. The storage period is long, but the cost is high and the operation is cumbersome. It is one of the simpler preservation methods, but the storage period is short, mostly 5-6 years

[0024] Specific implementation mode 2: Comparison of the inventive method on prolonging the storage time of peanut germplasm and maintaining quality
[0025] (1) Effects of the above preservation methods on the germplasm germination vigor of different peanut germplasms
[0026] Find out from Table 2, utilize processing method of the present invention, the peanut germplasm preserved in 2003, the germination rate of each type peanut seed all reaches more than 50% when germination test 5 days, all reaches 100% when 10 days. The vigor of germplasm seeds preserved in 1993 decreased slightly, and the vigor of ordinary peanut seeds was less affected at 5 days. Among them, the germplasm germplasm of semi-erect common type still reached 95% after about 12 years of storage, and the germplasm germination rate of erect common type up to 75%, indicating that the common type peanut germplasm has a stronger storability than other types of peanut germplasm. This shows that the method of the ...

The invention provides a method for preserving peanut germplasm resources under constant-temperature, dry and sealed condition. The method includes the following steps of: first stage, airing the harvested germplasm with water content being 40-60 percent for 4-5 days until the water content of peanut legume is 12-15 percent and the water content of kernel is 10-12 percent; second stage, continuing airing until the water content of the peanut legume is 8 percent and the water content of kernel is not more than 7 percent; and third stage, mothballing and placing the peanut germplasm in a constant-temperature store in time under the conditions of ambient humidity not more than 45 percent and ambient temperature not more than 18 DEG C. The constant-temperature store remains the ambient temperature at 18 plus or minus 1 DEG C and the ambient humidity not more than 45 percent.
Description
field of invention [0001] The invention relates to a method for prolonging the storage period of seeds and improving the vigor of seeds. Background technique [0002] Peanut is an important economic crop and oil crop in my country. Studies have shown that the main factors affecting the vitality of peanut germplasm are water content, storage temperature and storage time during the drying and storage of peanuts at room temperature. Stored under normal temperature and dry conditions, peanut germplasm will undergo a series of quality components and physiological and biochemical changes during storage, such as enzyme activity, storage material content, etc. Among them, temperature and humidity are the main factors affecting the material change process. [0003] Peanut germplasm storage methods are mainly divided into three methods, namely ultra-low temperature long-term storage, low-temperature medium-term storage and normal temperature short-term storage, ultra-low temperature l...
