因此，胚休眠主要在发育后期获得。
Therefore, the embryo dormancy is acquired in late stage of seed development.
结果表明，引起砂梨种子休眠的主要有种皮障碍、种胚休眠和种胚后熟；
The results showed: the major causes were obstacle of seed vessel, seed embryo dormancy and post-maturation;
种子休眠主要有两种休眠类型即由种皮引起的休眠和由胚引起的休眠。
There are basically two categories of dormancy, the one of which is caused by seed coat, the other of which is caused by embryo.
因此，对胚的ABA敏感性研究，将有助于了解种子休眠机制。
The study on embryonic sensitivity to ABA will help to understand the dormancy mechanism.
因而，母体对种子休眠的影响可能与胚的ABA敏感性无关。
Therefore, maternal (effect) on seed dormancy might be irrelative to embryonic sensitivity to ABA.
种子休眠主要有两种休眠类型即由种皮引起的休眠和由胚引起的休眠。
There are basically two categories of dormancy , the one of which is caused by seed coat , the other of which is caused by embryo.
延迟着床是指胚胎在发育到胚泡阶段时暂时进入休眠状态，并不立即着床。
Delayed implantation occurs when the conceptus enters a state of suspended animation at the blastocyst stage of development.
延迟着床是指胚胎在发育到胚泡阶段时暂时进入休眠状态，并不立即着床。
Delayed implantation occurs when the conceptus enters a state of suspended animation at the blastocyst stage of development.
