克隆繁殖
- 名clonal propagation
-
这种技术可以产生遗传物质相同的植株,因此称为是克隆繁殖。
The technique results in genetically identical plants and is therefore clonal propagation .

土壤养分的缺乏促使资源向垂穗披碱草贮藏器官的转移,而鹅绒委陵菜则没有出现这种转移。光照条件是制约两种克隆植物繁殖(包括有性繁殖和克隆生长)的主要限制因子。
Light was the main limited factor that restrained reproduction ( including sexual reproduction and clonal growth ) of the two clonal plants .
-
一些微生物,包括细菌和酵母,都是自然地通过克隆来繁殖(无性繁殖),而非通过精子和卵子的结合来繁殖。
Some micro organisms , including bacteria and yeast , naturally reproduce by cloning ( asexual reproduction ) rather than by the unity of a sperm and an egg .
-
克隆排除了繁殖这种全靠碰运气的事儿的偶然因素。
Cloning removes the chance element from the lottery of reproduction .
-
目前尚不清楚。同时从无性与有性繁殖两个方面综合考察克隆植物的繁殖对策是今后亟待加强的工作。
Few studies have investigated the reproductive strategies of clonal plants simultaneously both from sexual and asexual perspectives .

Some cloned animals have been successfully bred , including Dolly the sheep , the world 's first cloned mammal , which has given birth to several healthy lambs .
-
首先,许多克隆植物的有性繁殖与更新程度都很低,甚至有一些植物由于克隆生长而几乎完全放弃了有性过程,从而影响到克隆植物对局域环境的适应和地理范围进化。
First , in some clonal species , sexual reproduction and recruitment are very low and drop to nil in extreme cases . Variation in sexual reproduction may strongly influence the adaptation to local environments and the evolution of the geographic range .
