摘　　要：为明确‘香玲’和‘西林3号’核桃果实的生长发育规律,本研究通过测定果实生长发育过程中青果重、青果三径、鲜果重、干果重、干果三径、仁重、出仁率、含水率和含油率等经济指标动态变化特征,并分析各指标之间的相关性。结果表明,随着果实的生长发育,青果重、鲜果重、干果重、仁重和含油率总体呈增加趋势,‘西林3号’的果实大小、果重均大于‘香玲’。相关性分析显示,干果重与仁重、出仁率、含油率呈极显著正相关关系;果形指数与纵径呈显著正相关;壳厚与鲜果重、干果重呈显著正相关;表明干果重越大,仁重、出仁率越高。To elucidate the growth and development patterns of the walnut fruits of'Xiangling'and'Xilin No.3',this study measured the dynamic changes in various economic indicators during fruit development,including the weight of green fruits,the three diameters of green fruits,the weight of fresh fruits,the weight of dried fruits,the three diameters of dried fruits,the weight of kernels,kernel yield,moisture content,and oil content.Additionally,the correlations between these indicators were analyzed.The results indicated that as the fruits grew and developed,the weight of green fruits,fresh fruits,dried fruits,kernels,and oil content generally increased,with'Xilin No.3'exhibiting larger fruit size and weight compared to'Xiangling'.Correlation analysis revealed extremely significant positive correlations between the weight of dried fruits and the weight of kernels,kernel yield,and oil content.Furthermore,the fruit shape index was significantly positively correlated with the longitudinal diameter,while shell thickness was significantly positively correlated with the weight of fresh fruits and dried fruits.These findings suggest that as the weight of dried fruits increases,so do the weight of kernels and kernel yield.
