母株光照强度影响插条不定根的形成。有三种光照强度反应类型:第一种是高光照反应型,插条的生根力随母株光照强度的增加而提高;第二种是低光照反应型,插条的生根力在母株低光照下最强;第三种属于中间型,母株光照强度的改变对插条生根没有明显的效应。因此,插条生根随植物种的不同而需要不同的最适光照强度。母株光照强度影响插条不定根形成的机制尚未完全清楚。
The light intensity of parental plants affected the formation of adventitious roots. There are three types of light intensity response: the first is the high light response type, the rooting force of the cuttings increases with the increase of the light intensity of the mother plant; the second is the low light response type, Under the strongest; the third is an intermediate type, the light intensity of the parent plant rooting no significant effect. Therefore, the rooting of cuttings requires different optimum light intensity depending on the species of plant. The mechanism by which the light intensity of parent plants affects the formation of adventitious roots is not fully understood.
