摘　　要： 对石硖龙眼 3种粗度 (0 4 0～ 0 6 0cm、0 6 1～ 0 80cm、0 81～ 1 0 0cm)的结果母枝在花芽分化前后进行叶片的分析测定 ,并调查成花座果情况。结果表明 ,花芽分化前结果母枝在积累养分 ;花芽分化过程中 ,淀粉、N、P含量均呈下降趋势 ,可溶性糖、K、Ca含量则增加。石硖龙眼结果母枝径粗与花穗长度、抽穗率、平均每穗果数均呈高度正相关。优良的石硖龙眼结果母枝粗度应达到 0 7cm。 Investigated the flour set and fruit set, and analysis nutrition material in leaves on the fruit branches for different time, compared three degree diamond of fruit branch, 0.40～0.60cm、 0.61～0.80cm、0.81～1.00cm.The result showed us that nutrition materials were collected in fruit branches before flour beat .After that time, the concentration of starth, nitrogen(N),potasium(K) became lower. On the other hand, the concentration of solved sugar、P、Ca were increasing.The diamond of fruit branches showed some positive relationship for flour ear, ear rate, number of fruit each ear. The diamond for well fruit branch should be 0.7cm。
