β-罗勒烯对烟草普通花叶病毒防控效果的研究
|
Abstract:
β-罗勒烯作为一种在植物生理生态系统中起着关键通讯作用的信号分子，在防控烤烟烟草普通花叶病毒病(TMV)方面展现出了极为明显的效果。室内盆栽试验中，处理组发病率比对照组低49.6%，病情指数下降65.21%。大田试验中，β-罗勒烯效果优于化学农药，控制效果达57.67%至64.71%。病情上升率统计显示，β-罗勒烯诱导的植株病情指数仅上升18.68%，远低于化学农药和对照组。这表明β-罗勒烯不仅在初始阶段有效防控TMV，还能持续抑制病情恶化。这一系列数据表明，β-罗勒烯为大田防控TMV提供了一种创新、高效的方法，减少化学农药依赖，推动绿色农业发展，为农业现代化提供支撑。
β-Ocimene, as a signal molecule that plays a key communication role in the plant physiological ecosystem, has shown extremely obvious effects in the prevention and control of common Tobacco mosaic virus disease (TMV) in flue-cured tobacco. In the indoor pot experiment, the incidence rate of the treatment group was 49.6% lower than that of the control group, and the disease index decreased by 65.21%. In the field experiment, the effect of β-ocimene was better than that of chemical pesticides, and the control effect reached 57.67% to 64.71%. The statistics of the disease increase rate showed that the disease index of the plants induced by β-ocimene only increased by 18.68%, which was much lower than that of chemical pesticides and the control group. This indicates that β-ocimene not only effectively prevents and controls TMV in the initial stage, but also continuously inhibits the deterioration of the disease. This series of data shows that β-ocimene provides an innovative and efficient method for the field prevention and control of TMV, reduces the dependence on chemical pesticides, promotes the development of green agriculture, and provides support for agricultural modernization.
