摘要
本文详细报道了梨锈菌(Gymnosporangium haraeanum Syd.)的重寄生菌(Tuberculina sp.)的寄生及形态特征。梨锈重寄生菌寄生于梨锈菌的锈子器及其附近,锈寄生菌的分生孢子座将梨锈菌的锈孢子牢牢地封死在锈子器内最终消解。描述和测量了梨锈重寄生菌在自然条件和人工培养基上产孢结构、孢子等的形态特征及大小。
The parasitical and morphological characteristics of the hyperparasite (Tuberculina sp. ) were reported in details. The parasitism of hyperparasite occured on or nearby the accidia of the pear gall rust (Gymnosporangium haraeanum Syd. ) The aecidiospores, sealed tightly by the sporodochia , were degradated finally. On media and under natural conditions, the morphological characteristics and sizes of sporogenous structure, spores et al. were described and surveyed.
