| 摘 要： | 田间感病情况下，研究梨锈病对华酥叶片光合作用、丰产性、果实品质及树体生长势的影响，结果表明：随着叶片病情指数增高，净光合速率逐渐降低，到9级时，净光合速率出现负值；树体感病程度越重，生长势越弱，果实越小，果实可溶性固形物和还原糖含量降低，可滴定酸含量增加。

| Abstract: | The effects of pear rust disease on the photosynthesis,prolificacy,fruit quality and growth vigor of "Huasu" pear were investigated under the field condition.The results showed that the net photosynthetic rate decreased gradually along with the increase of the disease index of pear rust disease in leaves,and the net photosynthetic rate became negative when leaves disease index was up to grade nine.Moreover,tree disease index was negatively correlated to tree growth vigor,fruit size,content of soluble solids and reducing sugar,while was positively correlated to titratable acid content. |
