摘要
梨、苹果锈病的转主寄主是桧柏的两个不同类型。梨锈病的转主寄主树冠较稀疏,分枝角度较大,具针叶和鳞叶,在转主寄主上形成纺锤形瘿瘤,苹果锈病的转主寄主树冠较紧凑,分枝角度小,只具针叶,在转主寄主上形成球形或半球形的瘿瘤。
The alternte hosts of Gymnosporangium asiaticum and G. yamadai were found to be two different forms of junipers (Sabina chinensis) . The alternats host of G. asiaticum is characterized by its thinner crown and bigger branch angles with needle and scale leaves. Spindle shaped galls are formed on the infected host. The alternate host of G. yamadai is distinguished by its more dense crown and smaller branch angles with needle leaves only. Spherical or hemispherical galls are formed on the infected host.
