Abstract

Ethane was measured to know whether active oxyzens may induce phytoxicity in stressedcucumber plant.The time course of the increase in ethane evolution was the same as that of the increase of visible injury in all treatments except $SO_2$ treatment.This result showed that air pollutants-induced plant damages were closely related to ethane evolution.And evolution of ethane was more increased in combined stress than singly one,suggesting that phytotoxicity was more severe in complex sterss.Also, evolution of ethane was enhanced in the light condition and scavengers of active oxygen were inhibited,showing that plant damage that plant damage were cause by active oxygens.
