杂交水稻种子在贮存过程中，因生理代谢异常活跃，呼吸作用旺盛，促使种子劣变加速，结果造成杂交水稻种子生活力和活力下降．目前多采用低温库（１５℃）方法来保存杂交水稻种子，但使用成本较大．本试验用成本低、处理简便的贮前浸种回干方法对杂交水稻种子抗劣变能力的... Hybrid rice seeds in the storage process, due to abnormal physiological metabolism, strong respiratory effects, prompting the accelerated deterioration of seeds, the resulting hybrid rice seed viability and vitality decreased. At present, low temperature storage (15 ℃) method is used to preserve hybrid rice seeds, but the cost is high. This experiment with low cost, easy to deal with the pre-storage soaking back to the dry method of hybrid rice seed anti-degeneration ability ...
