一.实验的意义与目的小麦种子休眠期的长短依小麦的类型与品种而有相当大的差别。休眠期很短的小麦种子在田间成熟以後,如遇阴雨就在穗上发芽,使我们收获的小麦品质变坏。休眠期长的小麦种子就没有这种现象。如能了解各种类型、品种的小麦种子的休眠期以後,我们就可以设法减少这种损失。小麦种子的休眠期不仅品种与类型间有不同,而且栽培的环境条件对它们也有直接的影响;同时收获後保管的方法也可以改变小麦种子的休眠状态。因此由了解休眠期开始再
I. The significance and purpose of the experiment The duration of the dormancy of wheat seeds is quite different depending on the type and variety of wheat. Shorter dormant wheat seeds mature in the field, in case of rain sprouting on the ears, so that we harvested wheat quality deterioration. Long dormant wheat seeds do not have this phenomenon. Once we understand the dormancy of wheat seeds of all types and varieties, we can try to reduce this loss. The dormancy period of wheat seeds is not only different between varieties and types, but also the environmental conditions of cultivation also have a direct impact on them; at the same time, the methods of post-harvest storage can also change the dormancy status of wheat seeds. So by understanding the beginning of dormancy again
