Abstract

通过叶盘法对落叶松—杨栅锈菌Melampsora larici-populina Kleb.混合菌系Hj的4个无性系菌株Hj1,Hj2,Hj3,Hj4进行反应型测定,结果证明4个菌株致病力一致,属于1个生理小种.4菌株夏孢子不同接种浓度和杨树互作结果表明,随着夏孢子接种浓度的增加,感病杨树品种健杨Populus×euramericana cv.‘Robusta’、杂交杨P.deltiodes×P.trichocarpa、波兰15号杨P.×euramericana cv.‘Polska 15A’、川杨P.×szechuanica和卜氏杨P.purdomii产生的夏孢子堆数量增加;免疫品种美洲黑杨P.deltiodes不感病.
