用扫描电镜观察了中国三种松疱锈病菌的锈孢子、夏孢子和冬孢子堆表面形态。取自云南松正[Pinus yunnanensis Franch]、马尾松 [P.massoniana Lamb.]、樟子松[P.sylvestris var.mongolica Livim.]的松芍柱锈菌[Cronartium flaccidum (Albet Schw.)Wint.],取自云南松和黄山松[P.taiwanensis Hay]的栎柱锈菌 [C.quercuum Miyabe.]和取自红松(P.koraiensis Sieb.et Zuec.]的茶蔗生柱锈菌[C.ribicola J.C.Fischerex Rabenh.]的锈孢子表面都具突起,突起上都有环纹。三个菌种的锈孢子,都有一个明显的平滑区。生在东北茶藤子[Ribes manschuricum(Maxim.)Kom]、返顾马先蒿[Pedicularis resupinata L.]和芍药[Paeonia lactifloraPall.]上的冬孢子堆(柱)稍有差异可以相互区别,而夏孢子的形态基本相似。
The morphology of rust spores, summer spores and teliospores of three species of Pinus armandii in China were observed by scanning electron microscopy. Cronartium flaccidum (Albet Schw.) Wint from Pinus yunnanensis Franch, P. massoniana Lamb. And P. sylvestris var. Mongolica Livim. ], C.quercuum Miyabe. From P. yunnanensis and P. koraiensis Sieb.et Zuec. C. ribicola JCFischerex Rabenh.] Had protuberances on the surface and rings on the protuberances.The rust spores of the three species all had a distinct smooth zone.The Ribes manschuricum (Maxim. ) Kom]. The differences between the winter sporophytes (pillars) in Pedicularis resupinata L. and Paeonia lactifloraPall. Can be distinguished from each other, while the morphology of the uredospores is similar.
