为测定广东省7个烟草主栽品种对TMV和CMV的抗性情况,中山出入境检验检疫局、华南农业大学农学院研究人员采用TMV侵染的普通烟叶系列稀释液(CK、1∶10、1∶100、1∶1000、1∶10000、1∶100000)作浓度梯度,选用K326作中感品种对照,机械摩擦接种法接种7个烟草品种(K326、云烟87、RG17、9601、9032、MSK326、MS96-7)。同时,对不同烟草品种选用
To determine the resistance of TMV and CMV to seven tobacco cultivars in Guangdong Province, the researchers from Zhongshan Entry-Exit Inspection and Quarantine Bureau and Agricultural College of South China Agricultural University adopted TMV-infected serial dilutions of common tobacco leaves (CK, 1:10, (K326, Yunyan87, RG17, 9601, 9032, MSK326) were used as concentration gradient control, K326 was used as the susceptible variety control, mechanical friction inoculation method was used to inoculate 7 tobacco varieties , MS96-7). At the same time, different varieties of tobacco selection
