摘　　要：以‘尖把梨’为对照,对大果芽变‘尖把王’的主要性状进行调查比较。结果表明,‘尖把王’与‘尖把梨’物候期基本一致,树体和枝条节间没有显著差异;只是‘尖把王’当年生新梢变粗,较‘尖把梨’增加24.6%。‘尖把王’叶片变长变宽变厚,百叶变重,依次较‘尖把梨’增加16.2%、20.9%、21.4%、26.6%,而叶柄长二者无显著差异;‘尖把王’的花瓣变长变宽、花冠直径加大,依次较‘尖把梨’增加32.0%、20.8%、10.8%,而花柄长、直径无显著差异;‘尖把王’果实的单果重变重,是‘尖把梨’的2.2倍,纵、横径变大,分别比‘尖把梨’增加26.4%、37.0%;果心占比减小13.1%;‘尖把王’果实石细胞、总酸含量降低,比‘尖把梨’降低0.07%和0.35%,而果皮厚度、出汁率、可溶性固形物、总糖、维生素C无显著差异。Using‘Jianba Pear’as a control,this study investigated and compared the main characteristics of the transformation of big fruit buds into‘Jianbawang’.The results showed that the phenological periods of‘Jianbawang’and‘Jianba Pear’were basically the same,and there was no significant difference between the tree body and branch nodes;However,the new shoots of‘Jianba Wang’have become thicker,an increase of 24.6%compared to‘Jianba Pear’.The leaves of‘Jianbawang’become longer,wider,and thicker,and the louvers become heavier,increasing by 16.2%,20.9%,21.4%,and 26.6%respectively compared to‘Jianba Pear’.However,there is no significant difference in petiole length between the two.The petals of‘Jianbawang’have become longer and wider,and the diameter of the corolla has increased by 32.0%,20.8%,and 10.8%,respectively,compared to‘Jianba Pear’.However,there is no significant difference in the length and diameter of the flower stem.The single fruit weight of‘Jianba Wang’fruit has increased,which is 2.2 times that of‘Jianba Pear’.The vertical and horizontal diameters have increased,increasing by 26.4%and 37.0%respectively compared to‘Jianba Pear’.The proportion of fruit cores decreased by 13.1%。The stone cells and total acid content of the fruit of‘Jianbawang’decreased by 0.07%and 0.35%compared to‘Jianba Pear’,while there was no significant difference in peel thickness,juice yield,soluble solids,total sugar,and vitamin C.
