| 摘 要： | 采用单菌核分离法得到大豆菌核病菌,利用菌丝生长速率法测定了7株大豆菌核病菌的生物学特性及对多菌灵和腐霉利的抗药性.结果表明:供试菌株菌丝生长的最适温度是15～20℃,而菌核的产生则在15℃左右最多;大豆菌核病菌丝生长最适的环境为中性和偏酸性;不同菌核及病残体埋入土壤不同深度后越冬处理,病残体上菌丝不能越冬,而菌核能够越...

| Abstract: | Sclerotinia stem rot of soybean caused by the fungus Sclerotinia sclerotiorum was a world wide disease of soybeans in the soybean growing regions.Pure culture isolations of S.sclerotiorum were obtained by single sclerotium.Growth characteristics and fungicide resistance of S.sclerotiorum were determined by using mycelium growth rate method.The seven S.sclerotiorum collected from various locations of Heilongjiang province were used to determine growth characteristic and resistant to carbendazim and procymido... |
