Q: The cotton seeds that were harvested last year are not used up this year. Will they still be used for next year?
A: The cotton seed coat is thick, and the short coat is usually attached to the surface of the seed coat. The thermal conductivity is very poor. The shelf life under low-temperature and dry conditions can reach more than 10 years. It is a long-lived seed in various crops. However, under conditions such as high water content and temperature, cotton seeds are also susceptible to deterioration and their viability is completely lost within a few months.
The seeds that were not used up in the first year of spring are usually stored over the summer. Under the simple storage conditions of farmers, summer cotton seeds are easily degenerated and lose their viability under high temperature and humidity conditions. Relatively speaking, winter cotton seeds are more conducive to cotton seed preservation. At present, it has entered the winter season. The seeds can be tested for germination if conditions permit. If the germination rate is high, it can generally be used for breeding in the next spring.
