红萍的枝茎顶端的分枝(即顶芽)具有生长点组织,可以分裂产生新萍体,当新萍体长大后,分枝的基部即与母体发生断离,形成新的个体。这就是红萍的无性繁殖,也叫断离繁殖。为了探索不同气温条件下红萍断离繁殖过程中的顶芽生长速度,我们曾在1975年的春夏两季(4—8月)进行了一些观察。观察材料分两组,每一组观察四个红萍单株,每天观察测记一次。七月份以前每天下午一
The rhizome branches (ie, the top bud) at the top of the rhizome have tissue of growth points that can be split to produce new rhinoplast. When the new rhinoplast grows, the base of the rhizobial branch breaks away from the parent body to form a new individual. This is asexual reproduction, also known as off the breeding. In order to explore the growth rate of top buds during the reproduction of Rhododendron under different temperatures, we made some observations in the spring and summer seasons (April-August) in 1975. Observed materials were divided into two groups, each observed four rhododendron plants observed and recorded once a day. One afternoon every day before July
