Abstract
Tobacco seedlings in cross period were sprayed with 1 g·L-1 methyl jasmonate(MJ),ten-leaf tobacco plants,after being transplanted,were treated with the same treatment,and inoculated with cucumber mosaic virus(CMV),then the effects of MJ on resistance induction were studied.The results revealed that:21 d after inoculated with CMV,the disease indexes of tobacco plants treated with MJ was lower than CK,the inductiive effect was 43.24 %;The activities of POD,CAT,SOD,and the content of H2O2 in tobacco leaves increased under MJ treatment;After the tobacco plants were inoculated with CMV,the activities of CAT and SOD decreased,the activity of POD and the content of H2O2 increased.
