In order to study the allelopathy effects of continuous cropping soil on the rooting and growth of stem
cuttings in Pogostemon cablin and reveal the allelopathic effect of continuous cropping soil of P. cablin and its mechanism
initially, the changes of rhizogenesis characteristics and physic-biochemical during cutting seedlings were observed when
using uncultured soil and continuous cropping soil. The study showed that continuous cropping soil of P. cablin showed
inhibiting effects on root number, root length, root activity and growth rate, the rate of fresh and chlorophyll content of
cutting seedlings. Meanwhile, the activity and content of POD, PPO and IAAO in cutting seedlings decreased. Continuous
cropping soil of P. cablin can influence the normal rooting and growth of stem cuttings. |
