查询词典 proembryos

When the embryonic original cell divided to form multicellur proembryos, the cell wall of the external cell was thickened to form a clear cell boundary to separate from ambient cells that was a phenomenon of isolation The protoderm began to be differentiated in the period of globular embryoid, and the procambium differentiated clearly in period of torpedo embryoid.

正常的球形胚和某些畸形球形胚继续发育，在心形胚或鱼雷胚阶段又出现出畸形胚，可以分为：①无茎端生长点；②原形成层发育不正常；③外形畸形，如有的是连胚，有的呈指状，有的呈叶片状等等。畸形胚有的败育，有的能继续发育，在子叶胚阶段形成畸形的植株。

The microscopical observation showed that embryonal suspensor masses developed firstly into early stage proembryos,then into late stage proembryos.

显微观察表明，来自原生质体的胚性胚柄细胞团(ESM：embryogenic suspensor mass)，经早期原胚(ESP：early stage proembryos)阶段形成了后期原胚(LSP：late stage proembryos)。

The embryogenic cell first divided into multicellular proembryos,then globular embryoid,pearshaped embryoid,long embryoid,scutiform embryoid and mature embryoid.

胚性细胞继续分裂形成多细胞原胚，经球形胚、梨形胚、长形胚、子叶分化期到成熟胚，其发生的胚状体与单子叶合子胚形成具有相似的过程。

Many forest tree species have multiple archegonia which, after fertilization produce a number of proembryos

许多林木树种都有颈卵器，受精以后便产生许多原胚。

Many forest tree species have multiple archegonia which, after fertilization produce a number of proembryos

许多林木树种都有颈卵器，受精以后便产生许多原胚。在传粉与受精的间隔期间，他们毁坏了雌球花。

Phosphorylase mRNA was less in proembryos, but significantly increased in differentiation embryos accumulating transition starch.

原胚中的磷酸化酶mRNA表达较弱，到分化胚积累过渡性淀粉时才显著增加。

A lot of proembryos and heart-shaped embryos are abortive; however,the others may develop normally and grow into mature embryos.

胚在各个发育阶段尤其是球形胚和心形胚阶段，都可能败育，也可以正常发育成为分化完全的有效胚。2。

In the late globular proembryos, three regions could be identified, i.

在晚球形原胚内可划分出子叶形成区、胚芽原区和下胚轴—胚根原区。

In the experiment, three thawing methods, such as washing by water at 40℃, exposing at the room temperature of 25℃, and washing by tap water were used to estimate the effects of thawing methods on the survival rate after cryopreservation. The results showed that the relative survival rate of the calli with proembryos was higher than that of the general calli; and that different thawing methods had the same effect on the survival rate of longan calli by cryopreservation.

结果表明，具有原胚分化的胚性愈伤组织保存后的存活率明显高于普通胚性愈伤组织；40℃温水浴、25℃左右室温和自来水冲洗等3种不同的化冻方式对龙眼胚性愈伤组织玻璃化超低温保存后的存活率具有同样的效果。

Phosphorylase mRNA wasless in proembryos, but significantly increased in differentiating embryos accumulatingtransition starch.

原胚中的磷酸化酶mRNA表达较弱，到分化胚积累过渡性淀粉时才显著增加。
