| 摘 要： | 漂盘培育枯斑三生烟,苗期接种TMV后3、7、11、15、19、23、27、31 d分别取样测定其根系的活力和过氧化氢酶活性,并以未接种TMV烟苗根系活力和过氧化氢酶活性为对照。结果表明,枯斑三生烟接种病毒后,其根系CAT活性值与取样时间有较强的负相关性(r=-0.9,p<0.01)。根系活力最初迅速升高,之后又逐渐降低呈平稳趋势。

| Abstract: | The root vigor and CAT activity of Nicotiana tabacum cv.’Samsun NN ’ inoculated TMV were investigated in different time.The result showed that within one month,CAT activity value of its root system and sampling time had a strong negative correlation(r =-0.9,p <0.01).The root vigor of its root system were abruptly increased first,and later decreased to the trend of smooth. |
