土荆芥化感作用干扰了蚕豆幼苗的代谢过程。在土荆芥挥发性物质作用下，叶片

The allelopathic effect of soil schizonepeta interfered with the metabolism of broad bean seedlings. Under the action of the volatile substances of the schizonepeta, the metabolic disorder of the antioxidant system of the leaves, the CAT activity, MDA content and soluble protein content increased under the effect of low concentration, but decreased under the effect of high concentration, the POD activity showed a concentration effect

The effect of the mustard of the earth interferes with the metabolic process of the broad beans seedlings. Under the action of the volatile substance of tuan mustard, the metabolic disorder of the anti-oxidation system of the blades, the cat activity, the MDA content and the soluble protein content increased under the low concentration, while the activity of POD was reduced under the high concentration effect, the concentration effect was presented.

Allelopathy of Schizonepeta alternates the metabolism of broad bean seedlings. Under the action of volatile substances, the metabolism of antioxidant system was disordered, CAT activity, MDA content and soluble protein content increased under the action of low concentration, but decreased under the action of high concentration, POD activity showed concentration effect
