新疆南部气候干燥,夏季气温不高,很有利于种子贮藏。为了解种子贮藏期间活力变化情况,种用价值如何,我们对在自然条件下贮藏不同年限的小麦种子活力进行了测定。 测定方法是把贮藏1—14年的小麦种(袋装、室内常温、通风条件下自然老化),先用标准发芽法测发芽率,再用幼苗生长测 Xinjiang’s southern climate is dry, the summer temperature is not high, is very conducive to seed storage. In order to understand the changes of vitality during seed storage and the seed value, we measured the vigor of wheat seeds stored for different years under natural conditions. The measuring method is to store the wheat varieties stored for 1-14 years (bags, indoor normal temperature and natural aging under ventilation), the germination rate is measured by the standard germination method first, and then the seedling growth measurement
