- 摘要:
- 以5个蜜梨品种为试验材料，测定并分析了其叶形和果实品质特性。结果表明：“新世纪”、“圆黄”、“翠玉”、“翠冠”和“清香”5个品种叶形差异不显著。单果重由大到小排列顺序为：“圆黄”、“清香”、“翠冠”、“翠玉”和“新世纪”。从果形指数来看，“圆黄”、“清香”接近正圆形，“翠冠”、“翠玉”、“新世纪”扁圆形。单果重与果实横径、单果重与果实纵径都表现为正相关。形成了以横径和纵径为变量的单果重直线回归方程，其中横径与单果重的直线回归关系更紧密。各品种以“翠冠”和“清香”肉质较硬，其次为“圆黄”和“新世纪”，“翠玉”肉质最嫩。各品种在可溶性固形物含量方面差异不显著。
- Abstract:
- Taking five varieties of pear as test materials，determined characteristics for leaf and fruit of pear.The results showed that ‘Shinseiki’，‘Yuanhuang’，‘Cuiguan’，‘Cuiyu’ and ‘Qingxiang’ had no significant difference in the leaf.The weight from large to small order was ‘Yuanhuang’，‘Qingxiang’,‘Cuiguan’,‘Cuiyu’and ‘Shinseiki’.In fruit shape index，‘Yuanhuang’ and ‘Qingxiang’ were close circle.‘Cuiguan’，‘Cuiyu’ and ‘Shinseiki’ were flat circular.Fruit weight and fruit transverse diameter，fruit weight and fruit longitudinal diameter showed positive correlation.Linear regression equations were formed by the transverse diameter and fruit weight，longitudinal diameter and fruit weight，and the linear regression relationship between the transverse diameter and fruit weight was more closely.‘Cuiguan’ and ‘Qingxiang’ flesh was the most hard.‘Shinseiki’ and ‘Yuanhuang’ flesh was more hard.‘Cuiyu’ flesh was tender.Five varieties had no significant difference in the content of soluble solids.
