Geographical Species of Poplar Canker' Pathogen in Shaanxi Province
摘要
Abstract
The studies showed that poplar canker, caused by pathogenic fungi including Dothiorella gregaria Sacc. , Cytospora chrysosperma Fr. , Coniothyrium populinum Schulz. Et Sacc. And a few Fusarium sp. , mainly distributed in middle Shaanxi, poplar canker mainly caused by C. populinum Schulz. Et Sacc. And C. chrysosperma Fr. In northern Shaanxi, and there were few poplar canker caused by D. gregaria Sacc. In southern Shaanxi. Inoculating tests proved that D. gregaria Sacc. Showed strronger pathogenici-ty, C. populinum Schulz. Et Sacc. Had weaker pathogenicity, and both showed culture character and pathogenic differentiation in geographical isolates.关键词
