在滞育期间,小袋鼠呆在雌袋鼠的育儿袋里,因而推迟了子宫内第二个受精卵的发育。
This genetically determined resting stage, characterized by the cessation of development and protein synthesis and suppression of the metabolic rate, is called diapause.这种由遗传决定的休眠期被称为滞育,其特征是发育和蛋白质合成的停止以及代谢率的抑制。
Photoperiod produces little influence on the diapause of housefly larvae.光周期对家蝇幼虫滞育的影响不大。
