| 摘 要： | 用1 g.L-1茉莉酸甲酯(MJ)处理小十字期烟草幼苗,烟苗移栽后长至10片真叶时再用相同浓度MJ处理一次,并接种烟草黄瓜花叶病毒,研究茉莉酸甲酯对烟草黄瓜花叶病毒(CMV)的诱导效应.结果表明:接种CMV后21 d,MJ处理烟株的病情显著低于对照,诱导效果达到43.24%;MJ处理提高了烟草幼苗叶片内的过氧化物酶、过氧化氢酶及超氧化物歧化酶的活性和过氧化氢的含量;而接种CMV后,MJ处理烟株叶片过氧化氢酶、超氧化物歧化酶活性下降,过氧化物酶活性增强,过氧化氢含量明显升高.

| Abstract: | Tobacco seedlings in cross period were sprayed with 1g·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 H_2O_2 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 H_2O_2 increased. |
