浙江地处南方多雨地区,麦收期间经常下雨,大小麦收获以前容易在穗上发芽,以致造成不必要的损失,品质下降,并严重影响种子质量和安全贮藏,这种情况在休眠浅的品种尤为突出。一些休眠深的品种虽然可以减少这方面的損失,但如果种子在播种之前尚未通过休眠,也会因出苗率低、幼苗生长不整齐而影响产量。在育种工作中,为了加速繁育,种子收获以后需立即播种,休眠深的品种因不能及时发芽或很少发芽,而使育种工作受到影响。在调种和引种时,也会由于种子存在休眠现象,而无法准确鉴定种子的发芽率。鉴于这些情况,我们对大小麦的休眠特性进行了一些试验,以 Zhejiang is located in a rainy area in the south with frequent rains during wheat harvest. It is easy for sprouts of wheat and wheat to germinate before harvest, resulting in unnecessary losses, declining quality and seriously affecting seed quality and safety in storage. This is the case in shallow dormant species Particularly prominent. Although some dormant varieties can reduce this loss, but if the seeds have not been dormant before sowing, but also because of low emergence rate, seedling growth and irregularities affect the yield. In the breeding work, in order to speed up breeding, the seeds need to be sown immediately after harvesting. The deep dormancy varieties will affect the breeding work because they can not germinate in time or rarely germinate. In planting and introduction, but also because of seed dormancy, but can not accurately identify the germination rate of the seed. In view of these circumstances, we conducted some experiments on the dormancy characteristics of wheat and wheat
