| 摘 要： | 采用交互接种的方法对华山松疱锈病、红松疱锈病的病原菌茶藨生柱锈菌的致病性分化进行了研究。结果表明:(1)红松疱锈病的病原菌锈孢子只能侵染其本地的转主寄主植物东北茶藨子;(2)华山松疱锈病的病原菌锈孢子能转主侵染多种不同地区的茶藨子植物;(3)所有华山松疱锈病病原菌的锈孢子均不能转主侵染东北茶藨子;(4)初步认定马先蒿属植物不是华山松疱锈病病原菌的转主寄主。 |
| 关 键 词： | 茶藨生柱锈菌 致病力分化 转主寄主 华山松 红松 |

| Abstract: | Taking the method of cross-inoculation,the pathogenic specialization of Cronartium ribicola,the pathogen of Pinus armandi blister rust and Pinus koraiensis blister rust was studied.The results of the study are as follows:(1) The aeciospore of Pinus koraiensis blister rust can infect the Ribes mandshuricum only;(2) The aeciospore of Pinus armandi blister rust can infect the many species of Ribes growing in different areas;(3)Pinus armandi aeciospore can not infect Ribes mandshuricum;(4) Pedicularis is not the alternate host of Pinus armandi blister rust. |
| Keywords: | Cronartium ribicola pathogenic specialization alternate host Pinus armandi Pinus koraiensis |
