STUDIES ON THE CAUSE OF ROOT ROT OF KIWIFRUIT IN GUANGDONG PROVINCE

摘要: 从广东省和平县猕猴桃根腐病病根分离到２个菌株，根据培养性状及开矿特征，分别鉴定为ＰｈｙｔｏｐｈｔｈｏｒａｃｉｎｎａｍｏｍｉＲａｎｄｓ（交配型为Ａｌ）和Ｆｕｓａｒｉｕｍｓｏｌａｎｉ（Ｍａｒｔ．）Ｓａｃｃ．．室内人工接种表明；Ｐ．ｃｉｎｎａｍｏｍｉ有较强的致病力，Ｆ，ｓｏｌａｎｉ是第２次侵入者，单独不能为害，但在Ｐ．ｃｉｎｎａｍｏｍｉ为害的基础上，可加重猕猴桃根腐病的发生。

Abstract: Two pathogens were isolated from root rot of kiwifruit in Heping county, Guangdong Province. According to their cultural characters and morphology, they were identified as Phytophthora cinnamomi Rands ( mating type A1 )and Fusarium solani (Mart.) Sacc.. By artificial inoculation in greenhouse, it was showed that P.cinnamomi possessed higher pathogenicity, and F.solani was the second invader which could not attack the kiwifruit alone, but might accelerate the root rot together with P.cinnamomi.
