β-罗勒烯对烟草黄瓜花叶病毒防控效果的研究

Study on the Control Effect of β-Ocimene on Tobacco Cucumber Mosaic Virus

摘要: 在植物生理生态的通讯网络中，β-罗勒烯扮演着关键信号分子的角色，而当应用于烤烟黄瓜花叶病毒病(CMV)的防控时，其抑制病害、减轻危害的效果尤为突出。室内盆栽试验中，处理组发病率比对照组低55.5%，病情指数下降46.39%。大田试验中，β-罗勒烯效果优于化学农药，控制效果达63.75%至64.70%。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33.0%，远低于化学农药组和对照组。这表明β-罗勒烯不仅在初始阶段有效防控CMV，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CMV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。

Abstract: In the communication network of plant physiological ecology, β-ocimene acts as a key signaling molecule, and its effect of inhibiting diseases and reducing harm is particularly prominent when applied to the control of tobacco Cucumber Mosaic Virus (CMV) disease. In the indoor potted experiment, the disease incidence of the treatment group was 55.5% lower than that of the control group, and the disease index decreased by 46.39%. In the field experiment, notably, β-ocimene achieved a higher control efficiency than chemical pesticides, with the efficacy values ranging between 63.75% and 64.70%. Statistics on the disease progression rate showed that the disease index of plants induced by β-ocimene only increased by 33.0%, which was much lower than that of the chemical pesticide group and the control group. This indicates that β-ocimene not only effectively controls CMV in the initial stage but also continuously inhibits the deterioration of the disease. These data show that β-ocimene provides an innovative and efficient method for the field control of CMV, reduces reliance on chemical pesticides, promotes the development of green agriculture, and provides support for agricultural modernization.
