| 摘 要： | 本文描述了姜根茎腐烂的三种症状类型:青枯型、黄腐型及黄枯型;分别由青枯细菌、腐霉菌及青桔细菌和腐霉苗引起,鉴定出4种致病腐霉:P(?)(?)P.(?)P.(?)和P.(?).通过接种试验,证明腐霉对姜有较强的致病力;与青枯细菌共同为害,病将更严重,故姜的根茎腐烂不完全是细菌青枯病。

| Abstract: | Three types of symptom of rhizome rot of ginger were described,which were green wilt caused by Pseudomomas solonacearum,yellow rot by Pythium spp.,and yellow wilt by a complex infection of Pseudomcmas solanacearton and Pythium spp.,Four species of Pythitan were identified as Pythian myriotyhrm,P.graminioola,P.moaospermon and P.aphanidermation.The result of inoculation test showed that Pythtan spp.could cause ginger rhizome rot effectively,and the disease was more serious if ginger was infected silnultaneously by Pythium and Pseudomouas solomocecrum.It indicates that the ginger rhizome rot is not only caused by southern bacterial wilt. |
