可分裂的

We can regulate the site, time and level of cytokinin expression according to different study goals.

从而可根据不同的研究目的调控植物转化体中细胞分裂素合成的部位、时间和表达水平。

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than thesun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth. The bugs run out of food, or they poison each other, or they are shy about reproducing in public.

Carl Sagan 曾经开玩笑地解释这种现象，假设有一种细菌每15分钟可以分裂一次，亦即代表每一小时复制四次，一天可复制96次，虽然单一个细菌其重量只有一兆分之一公克重，但是只要经过一天无止尽的无性生殖，其重量可能会比一座山还重，经过两天后，甚至会比太阳还重，要不了多久所有的宇宙都将由这种细菌所组成，不过 Sagan 又说，大家不必担心，上天一定会安排障碍来阻止其倍数成长，有可能他会耗尽食物，或是毒死自己，或是有可能羞于在大庭广众之下复制。

A certain spot in the gastrula begins to act on surrounding cells, thus inducing fast cell division, local expansion, folding, invagination, tubular structures, inclusions, etc.

在原肠胚里某一斑点开始在周围的细胞行动，因此导致快速的细胞分裂、地方扩展、可摺叠、反折处、管状结构、胞吞等。

Under the same environmental conditions when the meiosis of microspore mother cell develop into tetrads the female buds were dipped duly with colchicine solution, which guaranteed that chromosome doubling of megaspore in white poplar could be accomplished in a short time. So much workload was cut down, and induction efficiency of triploid white poplars was also improved.

当相同生境以及培养条件下的小孢子母细胞减数分裂达到四分体后，适时采用秋水碱溶液对雌花芽进行浸泡处理，可保证白杨大孢子染色体加倍处理能集中于一个较短的时间段内进行，从而大大减轻了工作量，同时提高三倍体诱导效率和效果。
