Control Effects of Combination of Plant Induced Resistant Agents against Tobacco Mosaic Virus (TMV)
摘要
Abstract
[Objective] The paper was explore the control effects of combination of plant induced resistant agents against tobacco mosaic virus (TMV). [ Method] The control effects of 6 different combinations of plant induced resistant agents against TMV of flue-cured tobacco cultivar HongDa were studied under the environment of simulated disease nursery. [ Result] The combination of two induced agents polypeptide-agents and 3-acetonyl-3-hydroxyoxindole (AHO) had good control effect against TMV, which could obviously delay the incidence time of TMV in infected tobacco plants. With water and Duxiao as control, their average control effects against TMV of tobacco plants during field period reached 69.64% and 43.25% after transplanting for 70 d. They also showed obvious superiority in the aspects of plant height and leaf number, and the growth and development condition of leaves was good. Tobacco seedlings carrying TMV virus had no direct correlation with whether the symptoms performed, the seedlings carrying virus would perform symptom only when the incidence condition was suitable. The peak period for the incidence of TMV in seedlings carrying virus was during 19 d after transplanting. Spraying effective agents during nursery stage and field period, as well as promoting early growth and quick tiller of tobacco seedlings after transplanting were the key measures to control its incidence. [Conclusion] The study provided theoretical basis for preparing the control measures against TMV.关键词
