Effects of Storage Conditions on the Life of Crop Seeds

The so-called seed longevity is usually the longest term for which the seed can maintain its viability under certain storage conditions after it matures from the mother plant. As with all living organisms, seeds continue to carry out life activities inside cells. When the seed is fully mature, it breaks off from the mother plant, becomes an independent individual, and temporarily enters dormancy, appearing to stop growing on the surface. In fact, the physiology of the embryo is still going on, but it is very weak. However, many tests have shown that, under the climatic conditions of our region, the lifespan of cereal crops can generally only reach 1 to 3 years. In production, more seeds are used for the current year, and the seeds of the next year can also be used under normal circumstances. . However, in agricultural production, it is necessary to adopt various effective measures to maximize the life of crop seeds in order to select seeds that are in line with agricultural production. Therefore, the storage conditions will become the determinants of the seed's longevity, but what will be the life extension of the crop seeds?

Now that there is a refrigerator in the house, a small amount of crop seeds can be harvested and dried in the refrigerator, so that the viability can be maintained for more than 3 years. However, these seeds are rarely used in production for more than three years. This is mainly due to the fact that the storage time of crop seeds exceeds a certain limit and a series of physiological changes occur in the embryonic cells. Although the viability has not been completely lost, the original physiological activity has begun. In the recession, even if they can germinate long seedlings after sowing, they are often thin and short, deformed, and have abnormal growth and development, which affects product quality and yield.

Fortunately, the development of the TPZY seed standard sample library not only solves the adverse effects of refrigerator storage seeds, but also optimizes the storage conditions. The TPZY low temperature seed standard sample adopts the touch screen liquid crystal operator interface, which can select the optimal cooling or dehumidification operation mode according to the different kinds of storage goods, with high control precision, and also adopts dual temperature dual standby system. The TPZY seed standard sample library not only provides good storage conditions for the seeds, but also maintains the lifespan of the crop seeds for 3-30 years. It is of great significance for the biological theoretical research to provide rich germplasm and research materials. More importantly, it is Agricultural production provides quality seeds.
