玉米种子胚较大，并含较高的脂肪，在夏季高温高湿条件下，会迅速衰老，降低活力和发芽率。为了探讨玉米杂交种度夏安全贮藏的技术措施，我们借用我市闲置的恒温山洞仓库，连续３ａ（即１９９５～１９９７年）贮藏玉米杂交种子，试图为玉米杂交种子安全越夏贮藏提供一定的科学 Corn seed embryos larger, and contains higher fat, under the conditions of high temperature and humidity in summer, will quickly aging, reducing vitality and germination rate. In order to explore the technical measures for summer hybrid storage of summer hybrid maize, we borrowed the Hengsheng cave warehouse in our city for storage of maize hybrid seeds for continuous 3a (ie, from 1995 to 1997), trying to provide some science for safe storage of maize hybrid seeds in summer
