| 摘 要： | 分析了三环唑和多菌灵对水稻稻瘟病毒力及对品种抗病性的影响,结果表明三环唑和多菌灵对水稻品种与稻瘟病菌互作有重要影响。当喷雾0.2μg/mL三环唑于13个日本已知抗性基因品种时,原对ZE3和ZG1混合菌株表现抗性的爱知旭表现感病,当喷雾2μg/mL三环唑时,爱知旭则表现抗病,而在0、0.2μg/mL三环唑时均表现抗病的露明则在2μg/mL三环唑时表现感病;喷雾0.2μg/mL多菌灵于13个日本已知抗性基因品种时,ZB1、ZE3、ZG1混合菌株在0μg/mL多菌灵时表现抗性的爱知旭则表现感病,当多菌灵浓度为2μg/mL时,露明又表现为抗病,而在0、0.2μg/mL多菌灵时,对ZG1表现为抗病的草笛则表现感病;13个已知抗性基因品种中其他品种在使用了三环唑和多菌灵后抗性也发生了变化,这说明稻瘟病菌的分布和组成与这类杀菌剂的长期使用可能有一定关系。

| Abstract: | The influence of tricyclazole and carbendazim on Magnaporthe grisea and resistant cultivars was reported in this paper.The results showed that tricyclazole and carbendazim played an important role in the interaction between M.grisea and resistant cultivars.Aichi appeared sensitive to the mixed isolates of 2004-118-1(ZE_3) and 2004-184(ZG_1) when(0.2 μg/mL) tricyclazole was sprayed,but kept resistance to the mixed isolates when 0 and 2.0 μg/mL tricyclazole was sprayed.When 2.0 μg/mL tricyclazole was sprayed, Tsuyuake became sensitive to the mixed isolates of 2004-118-1(ZE_3) and 2004-184(ZG_1) but kept resistance to them at 0 or(0.2 μg/mL) tricyclazole.Aichi became sensitive to the mixed isolates of 2004-141-2-1(ZB_1),2004-118-1(ZE_3) and 2004-184(ZG_1) when(0.2 μg/mL) carbendazim was sprayed,but kept resistance to the mixed isolates at 0 or 2.0 μg/mL carbendazim.When 2.0 μg/mL carbendazim was sprayed,Fusijisaka became sensitive to 2004-184(ZG_1) but kept resistance to it at 0 or 0.2 μg/mL carbendazim.More than one variety with known resistance genes changed under different concentrations of tricyclazole or carbendazim.It indicated that the distribution and composition of M.grisea might be related to tricyclazole and carbendazim that were applied to control the disease for a long period of time in the field. |
