摘　　要：以大乌圆龙眼为试材,应用生物统计方法分析结果母枝单元直径、长度、复叶数、小叶数、小叶面积、总叶面积和着生角度7个自变量与穗开花总数、穗开雌花数、穗开雄花数、花穗长度、花穗宽度、花穗体积、穗坐果数、穗果重、单果重和可溶性固形物含量10个依变量的相关关系,结果表明:(1)结果母枝单元直径与穗开花总数、穗开雌花数、穗开雄花数、花穗宽度、花穗体积、穗坐果数、穗果重为显著或极显著的正单相关,与可溶性固形物含量为显著的多项式相关,对开花坐果及果实性状影响最大。(2)结果母枝单元总叶面积与穗开花总数、穗开雄花数为显著的多项式相关。(3)结果母枝长度与花穗宽度、花穗体积为显著正单相关。(4)结果母枝复叶数、小叶数、总叶面积与花穗宽度、花穗体积为显著或极显著正单相关,小叶数与穗坐果数为显著的正单相关,复叶数与单果重为显著的负相关。Biometric method was used to analyze the correlation of bearing branches with flowering, fruitsetting and fruit characteristics of longan cultivar ‘Dawuyan’（Dimocarpus longan Lour） . The bearing branches included 7 independent variables such as diameter and length of bearing branches, number of compound leaves, number of leaflets, leaflet area, total leaf area, bearing branch angle; the flowering, fruitsetting and fruit characteristics included 10 dependent variables： number of flowers per panicle, number of female flowers per panicle, number of male flowers per panicle, panicle length, panicle width, panicle volume, number of fruit per panicle, fruit weight per panicle, single fruit weight, and fruit soluble solid content. Correlation analysis showed that the diameter per bearing branch showed a highly significant or significant positive monomial correlation with the number of flowers per panicle, number of female flowers per panicle, number of male flowers per panicle, panicle length, panicle width, panicle volume, number of fruit per panicle, and fruit weight per panicle, and a significant polynomial correlation with fruit soluble solid content, and exerted the highest impact on the flowers, fruit setting and fruit characteristics. Total leaf area per bearing branch was positively correlated with the number of flowers per panicle, the number of male flowers per panicle. The length per bearing branch showed a highly significant positive correlation with the panicle width and volume. The number of compound leaves, the number of leaflets and the total leaf area of bearing branches had highly significant positive monomial correlation with panicle width and volume. The number of leaflets of bearing branches showed a significant positive monomial correlation with the number of fruit per panicle, but the number of compound leaves of bearing branches was significantly negative correlated with single fruit weight.
