摘　　要：选取27种不同品种的梨果,分早、中、晚熟品种,分别对其果形指数、单果质量、酸度、硬度进行测定比较。结果表明:平均果形指数,早熟品种为0.89～1.31,中熟品种为0.88～1.20,晚熟品种为0.84～1.26;平均单果质量,早熟品种为198.22～524.23 g,中熟品种为165.35～314.25 g,晚熟品种为171.61～459.12 g;平均硬度,早熟品种为5.9～14.7 kg/cm2,中熟品种为3.6～9.7 kg/cm2,晚熟品种为4.6～9.1 kg/cm2;平均酸度,早熟品种为0.14%～0.22%,中熟品种为0.11%～0.27%,晚熟品种为0.07%～0.13%。测得的数据与理论数值基本相符。27 pear varieties,including early,middle and late maturing ones,were chosen to conduct comparison of their fruit shape index,single fruit weight,acidity and hardness.Experimental results showed that the early maturing varieties had 0.89～1.31 average shape index,the middle maturing varieties 0.88～1.20 average shape index,and late maturing varieties 0.84～1.26 shape index;as for single fruit weight,the mean early maturity varieties 198.22～524.23 g,the middle ones 165.35～314.25 g,and the late ones 171.61～459.12 g.As for the mean hardness,the early ones 5.9～14.7 kg/cm2,the middle ones 3.6～9.7 kg/cm2,and the late ones 4.6～9.1 kg/cm2;as for the mean acidity,the early ones 0.14%～0.22%,the middle ones 0.11%～0.27%,and the late ones 0.07%～0.13%.In the main,all the test results agreed with theoretical values.
