本文报导了对云南西双版纳橡胶树叶片和割面上分离的75个疫霉菌株的初步研究,第一批鉴定的48个菌株分属于P·cactorum、P·palmivora、P·capsici和P·citrphthora等四个种,其中P·cactorum和P·palmivora仅从叶片上分离获得,P·capsici和P·citrophthora在叶和割面上均有分布。P·capsici数量多,分布广,是西双版纳橡胶树上的优势种。
In this paper, we report the preliminary studies on 75 P. phyllacetica strains isolated from leaves and cut surfaces of Xishuangbanna, Yunnan. The first 48 strains were identified as P. cactorum, P. palmivora, P. capsici and P. citrphthora Among them, P. cactorum and P. palmivora were isolated from leaves only, P. capsici and P. citrophthora both distributed on leaves and cut surfaces. P · capsici number, wide distribution, is the dominant species in Xishuangbanna rubber tree.
