| Abstract: | The investigation of Dothiorella gregaria of poplar involving five varieties from different areas in Shaanxi Province showed that the resistances of different poplar species to D.gregaria varied significantly(p<0.05) in the same area.The resistance of Populus deltoids × P.nigra was the highest in Middle Shaanxi,followed by P.alba ×P.glandulosa,Populus × euramericana cv.’74/76’ and P.tomentosa.The disease index of the same poplar species varied significantly(p<0.05) among different climatic zones.P.tomentosa in Middle Shaanxi was more seriously infected with D.gregaria than that in the north of Tongchuan.P.alba × P.glandulosa was slightly infected with D.gregaria in Mei County of Baoji,but P.alba × P.glandulosa was badly infected in Yaozhou District of Tongchuan.There was not significant correlation between canker disease index and diameter at breast height(tree age) of poplar or site conditions. |
