| 摘 要： | 目测及镜检表明，褐锈病菌被锈寄生菌寄生后，夏孢子堆由桔红色渐变为灰褐色，后期夏孢子失去发芽力，孢子堆原基处只存有寄生首的分生孢子器。锈寄生菌的发酵液代谢产物中含有３种抗生物质。自７月中、下旬至９月中、下旬，分生孢子的发生量多于褐锈菌的孢子量，表明褐锈病的发生程度随着锈寄生菌寄生率的增加而减轻。

| Abstract: | Ocular and microscopic obervations showed that when T. laricinum was parasitized by S. filum, thecolour of its urediosporus changed from reddish orange to grey brown. At later stage, the uredio-spores lose theirgerthenating ability, and only S. filum conidia were found at uredinoid matrix. The metabolic products in fermentationliquid of S. filum contained three resistant substances. From the second ten days of July to the second ten daysof september, the amount of conidia was more than that of urediosPOres, indicating that the infered level byT. laricinum decreases with the increase of parasitic rate of S. filum. |
