| 摘 要： | 目测及镜检结果表明，褐锈菌被锈寄生菌寄生后，夏孢子堆由桔红渐变为灰褐，后期夏孢子失去发芽力，孢子堆原基处只存有寄生菌的分生孢子器．锈寄生菌的发酵液代谢产物含有３种抗性物质．自７月中下旬至９月中旬，分生孢子的发生量多于褐锈菌的孢子量，表明落叶松褐锈病的发生程度随着锈寄生菌寄生率的增加而减轻．

| Abstract: | Naked eye and microscopic observations show that when T. laricinum is parasitized by .S.filum, the colour of its urediosporus is changed from reddish orange to grey brown. Atlater stage, the urediospores lose their germinating ability, and S. filum conidia Only occur at uredinia base. The metabolic products in fermentation liquid of S. filum containthree resistant substances. From the second ten days of July to that of September, theamount of conidia is more than that of urediospores, indicating that the infected level byT. laricinum is decreased with increasing parasitic rate of S. filum. |
