This test studied the cryopreservation and usual preservation of gametophytes of Undaria pinnatifida.
本文以裙带菜配子体为实验材料，用包埋脱水法进行超低温和常低温保存。
Firstly, transgenic kelp gametophyte cells were cultured in the shake flask to find the growth characteristic of gametophytes.
首先，摇瓶悬浮培养配子体细胞，考察配子体细胞的生长特性。
If such gametophytes produce fertile gametes, the resulting sporophyte is then tetraploid, and large polyploid series may subsequently be developed.
如果这种配子体能够产生可育的配子，那么形成的孢子体通常是四倍体，这样就可以得到大量的多倍体。
An orange colored colony was found surrounding the gametophytes on AGAR plate for more than 10 days' incubation and this strain was identified as same as the Cytophage isolates GE04.
将用抗生素处理过的海带配子体置于平板上培养还观察到在丝状体周围形成单一的橙黄色菌落，分子鉴定证明该菌株为嗜纤维菌株ge04。
In meiosis, the pollen mother cells that abnormally acted made up about 10.28% and the male gametophytes abnormally acted at a frequency of 3.2% and mainly aborted at uninucleate stage.
减数分裂过程中染色体行为异常的花粉母细胞约占10.28%；雄配子体发育过程中异常频率约为3.2%，败育主要发生在单核期。
The material for studies on molecular mechanism of genetic regulation in the course of ovule development and gametophytes forming were mainly from the finding and inducement of mutation.
胚珠发育和雌配子体形成过程中遗传控制分子机理研究的材料主要来源于对突变体的发现和诱导。
