Abstract:

The purpose is to analyze the germinability change of spring wheat seeds in common storage condition, then provide a practical basis for the long time storage of spring wheat seeds. 15 accessions of spring wheat were used as materials, germination potential and germination percentage in 2009-2017 were determined, and the changes of germination potential and germination percentage of spring wheat seeds with storage years were analyzed. The results showed that the germination potential and germination percentage decreased with the increase of storage years in common storage condition. The annual descending rate of germination potential was faster than that of germination percentage. The change of germination potential and germination percentage were different among varieties along with storage years. The same wheat variety was affected by the interaction effect between varieties and harvesting environment, and the changes of the germination potential and germination percentage with storage years were different in different environments of planting and harvesting. Therefore, when testing the germinability of stored wheat seeds, we should determine the seed batch one by one according to the storage years, varieties and different sources of the same variety, they cannot be substituted randomly.

Key words: spring wheat, seed, storage year, germination potential, germination percentage
