摘　　要：为研究不同抗寒性梨品种的叶片组织解剖结构的差异性,采用石蜡切片法对16个梨品种进行叶片组织解剖结构的观察并测定了栅栏组织等结构参数。大香水、小香水、尖把、花盖属于等级最高的极抗寒类;伏香梨属于高抗寒类;南果、寒雅、苹果梨、早梨18和苹香、寒香、寒酥、寒露、蔗梨、寒红分别为中抗寒和抗寒类。结果表明,栅海比和细胞结构的紧密度越大,梨品种抗寒性越强,初步断定可能作为评价梨抗寒性大小的形态指标,叶片表皮厚度与梨品种抗寒性强弱无关。In order to study the difference of leaf tissue anatomical structure of different cold resistant pear varieties,the anatomical structure of leaf tissue of 16 pear varieties was observed by paraffin section method,and the structural parameters such as palisade tissue were measured,combined with the results of field freezing injury of 16 pear varieties.Daxiangshui,Xiaoxiangshui,Jianba,Huagai belongs to the highest grade of extreme cold resistance,Fuxiang belongs to the second class of high cold resistance,Nanguo,Hanya,Pingguoli,Zaoli18 are the middle cold and Pingxiang,Hanxiang,Hansu,Hanlu,Zheli,Hanhong are cold resistant categories.The results showed that the closer PTT/STT is to the cell structure,the stronger the cold resistance of pear varieties.It was concluded that it might be used as a morphological index to evaluate the cold resistance of pear,and the thickness of leaf epidermis was not related to the cold resistance of pear varieties.
