摘要
为了探寻一种更有效且绿色环保的烟草花叶病毒病(Tobacco mosaic virus,TMV)防治方法,采用室内盆栽和大田试验相结合的方法,测定了0.02%二氢卟吩铁(Iron chlorin e6,ICE6)对TMV的防控效果和对烟草的促生作用。结果表明,ICE6对TMV防治效果随浓度的增加而增强,稀释5000倍液处理防效最好,室内和大田试验防效分别为73.20%和72.35%,且趋势一致。同时ICE6可显著提高叶片暗反应中的PSII最大光化学量子产量(F_(v)/F_(m))和PSII潜在活性(F_(v)/F_(o))值,5000倍稀释液处理较清水对照分别提高16.99%和46.62%。此外,ICE6对烟草株高、叶长、叶宽和单叶质量有明显的促进作用,施用后增产效果显著,产量和产值分别比对照组增加9.34%和21.35%;且烟碱、总氮、还原糖、总糖、钾、氯、糖碱比均有显著提升。表明ICE6可有效防治烟草TMV,且对烟草植株的生长和烟叶品质提升具有促进作用。
To find a more effective and green way to control tobacco mosaic virus disease,the combination of pot experiment and field experiment were performed to determine the control effect of 0.02%ICE6 against TMV,as well as the growth-promoting effect on tobacco plants.The results of pot experiment showed that the control effect of ICE6 on TMV increased with the increase of treatment concentration,and the highest control efficiency(73.20%)was obtained when 0.02% ICE6 was diluted with 5000 times.The control efficiency of ICE6 in field trial exhibited the same trend as that of the pot experiment.Meanwhile,ICE6 could significantly increase F_(v)/F_(m) and Fv/Fo values in tobacco leaves,and the values of the treatment with 5000 times diluted solution increased by 16.99%and 46.62%,compared with the control treatment.In addition,ICE6 showed obvious promoting effects on tobacco plant height,leaf length,leaf width and single leaf quality.After application,the tobacco production raised significantly,increased by 9.34%and 21.35% per 666.7 m^(2),respectively.And eight chemical components in the ICE6 treated flue cured tobacco increased significantly,especially with the 0.02% ICE65000 times solution treatmenst.The above results demonstrated that ICE6 could not only enhance tobacco resistance against TMV,but effectively promoted the growth of tobacco plants as well.
