Ho,H.H.等人(1984)曾详细报导过西双版纳橡胶树和胶园土壤的几十个疫霉分离物的鉴定结果,其中两个土壤分离物被鉴定为芋疫霉(P.colocasiae Raciborski),通过人工接种能使橡胶叶和15天苗龄的橡胶幼苗致病;还认为P.colocasiae这个种对橡胶病害的发展可能起一定作用。为进一步弄清P.colocasiae在西双版纳地区能否成为橡胶树的病原,我们特做如下接种试验,现将结果报导于下。 The identification of dozens of Phytophthora isolate in rubber tree and plasticized soils of Xishuangbanna was reported in detail by Ho, HH et al. (1984), in which two soil isolates were identified as P. coliocasiae Raciborski, Artificial inoculation can cause rubber leaf and 15-day-old seedlings of rubbery seedlings; it is also believed that this species of P.colocasiae may play a role in the development of rubbery diseases. In order to further clarify whether P.colocasiae can become a rubber tree pathogen in Xishuangbanna Prefecture, we specially made the following inoculation test. The results are reported below.
