乳核

其初生胚乳核的休眠期为1天左右。

The rest period of primary endosperm nucleus was about 1 day long .

初生胚乳核的静止期为2&4小时。

The resting period of the primary endosperm nucleus is 2 to 4 hours .

初生胚乳核的几次分裂胚乳核基因主要以显性效应作用于整精米率，胚乳加性效应不显著。

Several divisions of primary endosperm nucleus Maternal additive effect was more important than maternal dominant effect .

主要结果如下：（1）二棱大麦胚乳核的分裂有两种方式：有丝分裂与无丝分裂，并以有丝分裂为主；

The major results are as follows : ( 1 ) Barley endosperm nucleus division has two forms : mitosis and amitosis , and the former is the majority .

胚乳发育属核型，初生胚乳核常常晚于合子分裂，胚乳核的分裂速度慢于胚体细胞的分裂速度。

The development of endosperm was of Nuclear type . The primary endosperm nucleus division was often posterior to zygote , and its division speed was also slower than that of embryo cells .
