用叶片扦插进行无性繁殖的方法称为“插叶法”。这种方法获得的新植株,由于各个叶片来自一个亲本,而不象有性繁殖那样来自两个亲本,因此,遗传性比较保守,不易发生变异,亲本的优良性状,能够相对稳定地在后代保留下来。快速繁育优良品种,获得杂种优势利用的纯系,保持雄性不育以及防止种性退化,都可采用“插叶法”。我们利用“插叶法”扦插成一批甘蓝、大白菜植株,有的品种已抽苔开花。新径公社 The method of vegetative propagation with leaf cuttings is called “leaf cut method.” The new plant obtained by this method, since each leaf comes from one parent, but not from two parents like sexual reproduction, therefore, the inheritance is relatively conservative and the variation is not easy to occur. The excellent traits of parents can be kept relatively stable in later generations Down. Rapid breeding of fine varieties, access to heterosis utilization of pure lines, to maintain male sterility and prevent the degeneration of species, can be used “plug leaf method.” We use the “plug-in” cuttings into a group of cabbage, cabbage plants, some varieties have bolting flowering.
