油松与赤松疱锈病是两针松类枝干上的重要病害,从油松和赤松主干病皮上取锈孢子分别向山芍药、芍药、返顾马先蒿、轮花马先蒿、长白茶藨子、东北茶藨子、香茶藨子和刺李进行室内和室外人工接种试验,终于在山芍药、芍药上接种成功,产生与自然状态下相同的典型症状。同样方法用夏孢子接种也都成功,在两种芍药上所产生的夏孢子堆与冬孢子柱以及夏孢子与冬孢子的形态也基本相同。由此可以肯定,油松疱锈病与赤松疱锈病是同一病原,病原菌为松芍柱锈菌[cronartium flaccidum(Alb·et Schw·)Wint]。取锈孢子用同样方法经多次在返顾马先蒿、轮花马先蒿、长白茶藨子、东北茶藨子、香茶藨子和刺李上接种,均未成功,因此认为这些植物与此两种疱锈病的发生无关,两种疱锈病在辽宁的转主寄主是山芍药(Paeonia obovata Haxim.)和芍药(P.lactiflora Pall.)。
Pinus tabulaeformis and Japanese red pine rust is an important disease on Pinus tabulaeformis, taking the rust spores from Pinus tabulaeformis and Pinus sylvestris var. Sylvestris var. Mongolica, respectively, to Peony, Paeonia lactiflora, Artemisia annua, Artemisia annua, Chardonnay, Chaxingu and Thorn Lee were tested for indoor and outdoor artificial inoculation. Finally, they were successfully inoculated on Mount Shanyao and Paeonia lactiflora to produce the same typical symptoms as the natural state. The same method with the summer spore inoculation are also successful in the two kinds of peony on the summer spore reactor and the winter spore column and the shape of the summer spores and winter spores are basically the same. It can be concluded that Pinus tabulaeformis is the same pathogen as that of Japanese red pine rust, and the pathogen is cronartium flaccidum (Alb · et Schw · Wint). Taking the same method of spore rusting were not successful after many times in the remediation of Artemisia annua, Artemisia annua L., Paeonia lactiflora, Paeonia lactiflora, Paeonia lactiflora and Thorn plum, Blister rust has nothing to do, the two blister rust in Liaoning host the main host is Paeonia obovata (Paeonia obovata Haxim.) And Paeonia lactiflora (P. lactiflora Pall.).
