在控制条件下接种烟草赤星病菌的试验结果表明 ,在品种和菌株组成一定的情况下 ,接种温度 (DT)和叶面湿润时数 (WD)是影响病菌侵染的 2个主要因素。接种温度在 12～ 37℃范围内 ,病菌可以侵染寄主 ,成功侵染的最适温度为 2 7～ 30℃。在适宜温度条件下 ,接种后保湿 2h病菌即可侵入 ,保湿时间延长 ,侵染概率增大。侵染概率与接种温度、叶面湿润时数及其互作之间具有线性关系。
The results of inoculation of R. solani under controlled conditions showed that inoculation temperature (DT) and leaf wetting time (WD) were the two main factors influencing pathogen infection under certain composition and strain composition. Inoculation temperature in the range of 12 ~ 37 ℃, the bacteria can infect the host, the optimum temperature for successful infection 27 ~ 30 ℃. In the appropriate temperature conditions, inoculation after inoculation moist 2h bacteria can invade, moisturizing time, increase the probability of infection. There is a linear relationship between infection probability and inoculation temperature, leaf wetting hours and their interaction.
