摘　　要：为优化山东聊城的梨品种结构,筛选适宜栽培的优质早熟梨品种,引进并调查8个早熟梨品种的物候期、生长结果习性、果实性状、抗性等。结果表明,中梨4号果实成熟期最早,7月14日成熟,早红玉最晚,8月16日成熟;中梨4号、鄂梨2号树势强健,苏翠1号、苏翠4号树势较弱,鄂梨2号的成枝力和单株产量最高,早酥蜜成枝力与单株产量最低;中梨4号,鄂梨2号单果重最小;苏翠1号、鄂梨2号可溶性固形物含量较高,中梨4号硬度和总酸含量较高,早红玉可溶性固形物、硬度和总酸含量最低;品种抗性除早酥蜜对白粉病中抗外,其他品种均高感白粉病。综上认为,中梨4号、鄂梨2号综合性状表现优异,适宜在山东省聊城地区推广种植。In order to optimize the pear variety structure in Liaocheng,Shandong province,and select high-quality and early-ripening pear varieties suitable for cultivation,the phenological period,growth and fruiting habits,fruit traits,resistance and other main traits of 8 pear varieties were investigated.The result demonstrated that Zhongli 4 had the earliest fruit ripening period,on July 14th,and was an extremely early maturing variety.Zaohongyu matured at the latest on August 16th.Zhongli 4 and Eli 2 had strong tree vigor and perform well,but Sucui 1 and Sucui 4 was weak and their performance was poor.The branching ability and single plant yield of Eli 2 were the highest,while Zaosumi were the lowest.Zhongli 4 had the largest single fruit weight,while Eli 2 was the smallest.Sucui 1 and Eli 2 had higher soluble solids,and Zhongli 4 had higher hardness and total acid content,while Zaohongyu had the lowest soluble solids,hardness,and total acid content.Except for Zaosumi which was moderately resistant to powdery mildew,all other varieties were highly susceptible to powdery mildew.Overall,Zhongli 4 and Eli 2 had excellent comprehensive performance and were suitable for cultivation in Liaocheng,Shandong Province.
