There are many types of vegetables, the morphology of seeds is also different, and the structure is complex, so the quality of vegetable seeds shows complexity. In every process of seed production, each link has an impact on seed quality. The seed's clarity is also one of the important indicators of seed quality, which can be controlled through screening and other methods. Therefore, in the process of improving seed quality, it is necessary to effectively control the cleanliness of the seed and use the seed cleanness table for effective inspection.
Variety hybrid degradation refers to the phenomenon that the purity of the variety in the process of production and cultivation is reduced, the species has a bad variation, the original morphological characteristics of the variety are lost, the resistance to stress, the adaptability decrease, the yield declines, and the quality deteriorates. Mixed degradation causes:
Mechanical miscellaneous refers to the lax operation in the breeding process of improved varieties, so that a good variety is mixed with other crops or seeds of different species, varieties, and types of the same crop. This is the main reason for the mixed variety. This phenomenon occurs in such areas as seed harvesting, drying, transportation and storage.
In the process of seed propagation and seed production, different varieties were not properly segregated and natural hybridization occurred, which resulted in a decrease in the purity of the variety, a decrease in yield and quality, and a loss of proper high yield performance. This phenomenon is likely to occur in most crops, but it is even more pronounced in cross-pollinated and often cross-pollinated crops, and is common across different crops of the same crop. After the occurrence of biological intermixing, the progeny produce segregation of traits and various types of mutant plants. These unstable plants reduce the consistency of the varieties, and some unhealthy individuals appear, causing deterioration of certain economic traits and disease resistance. The weakening of stress resistance has a great impact on seed quality.
When all kinds of impurities or even other seeds are mixed, the clarity of the seeds can generally require more patience for analysis. The seed netity table can effectively control the seed's clarity quality under the seed cleanness test.
