小麦种子休眠是长期自然选择的结果,其除了生物学意义外,在农业生产上也有一定作用。一方面具有休眠特性可以避免母株萌发,也可提供贮藏的安全性;另一方面小麦种子休眠给生产带来一定不便。如采用未度过休眠期的小麦种子播种,出苗率往往很低,并且出苗时间大为延长,耽误生产季节,影响了小麦产量,特别是在秋播前期,要了解小麦种子的发芽率,以确定是否有种用价值,而此时小麦种子正处于休眠状态,难以及时、准确的测出 Dormancy of wheat seeds is the result of long-term natural selection, which, in addition to its biological significance, plays a role in agricultural production. On the one hand, the dormancy feature can prevent the germination of the mother plant and also provide the safety of storage; on the other hand, the dormancy of the wheat seed brings some inconvenience to the production. Such as the use of non-dormant wheat seeds sowing, the emergence rate is often low, and the emergence of much longer, delayed production season, affecting wheat yield, especially in the early autumn sowing, to understand the germination rate of wheat seeds to To determine whether there is a kind of value, but this time the wheat seeds are in dormant state, it is difficult to detect timely and accurate
