Abstract
|
|
|
|
To evaluate allelopathic effect of volatile chemicals and phytohormones, seed germination and seedling growth test of Lactuca sativa have performed in laboratory experiments. Among used chemicals terpienen-4-ol was the most inhibitory to seed germination of lettuce. ABA and GA inhibited seed germination at 5×10 exp (-6) M concentration but promoted germination at 2.5×10 exp (-5) M and 5×10 exp (-5) M. ABA and GA alleviated volatile chemical-induced inhibition of seed germination and seedling elongation of lettuce.
