| 摘 要： | 通过外源水杨酸（Salicylic acid，SA）处理烟苗，研究了水杨酸处理的烟草接种黄瓜花叶病毒后，其病情指数及抗病相关酶活性和H2O2含量的变化。结果表明：接种CMV后21d，SA处理烟株的病情指数显著低于对照；SA预处理的烟株在接种CMV前后叶片内的过氧化物酶（POD）活性和过氧化氢（H2O2）含量提高，过氧化氢酶（CAT）活性下降。表明水杨酸具有诱导烟草抗黄瓜花叶病毒的效应。

| Abstract: | The changes of enzyme activities of peroxidase(POD)and catalase(CAT),the content of hydrogen peroxide(H2O2)and the disease occurrence were studied after the tobacco leaves were treated with salicylic acid(SA),then were inoculated with cucumber mosaic virus(CMV)the next day.The results showed that,after 21 d of inoculation with CMV,the disease indexes of tobacco plants treated with SA was lower than CK,and the activity of CAT decreased,while the activity of POD and the content of H2O2 increased in the plants... |
