摘　　要：调查水晶蜜柚成年树的结果母枝长度、粗度以及有叶结果枝长度、叶片数情况,分析其着果关系。结果表明,结果母枝长度在10~30 cm着果数(比例为70.10%)和有叶结果枝(比例为74.23%)最多;结果母枝粗度在0.5~0.8 cm、>1.0 cm时着果数(比例为82.72%)和有叶结果枝(比例为77.00%)最多;有叶结果枝叶片数在1~8片结果枝最多,着果数(比例为72.00%)也是最多的;有叶结果枝长度在5~15 cm果枝数与着果数(比例为57.00%)最多;母枝长度、粗度与有叶果枝结果数无显著性相关;有叶果枝叶片数与结果数呈极显著正相关性(r=0.998^(**),p=0.000);有叶果枝长度为5~15 cm时,果枝数与着果数最多,但有叶果枝长度与果枝数和挂果数无显著相关性,果枝数与挂果数呈极显著正相关性(r=0.998^(**),p=0.000)。综合可得,水晶蜜柚结果母枝以长度<30 cm、粗度<1.0 cm的枝条为主,有叶结果母枝主要是长度<15 cm,叶片数<8片。To investigate the length and thickness of parent branches,the length of leaf-bearing branches,and the number of leaves of adult Shuijing honey pomelo trees and to analyze the relationship between these parameters and fruit set.The results showed that number of fruiting(70.10%)and foliated fruiting(74.23%)branches in 10-30 cm was the greatest.The results The number of fruit-bearing(82.72%)and leaf-bearing branches(77.00%)was biggest when the parent branches were 0.5-0.8 cm and>1.0 cm in diameter,respectively.The number of leaf-bearing branches in the range of 1-8 was the greatest,and the number of fruiting branches(72.00%)was also the greatest.The number of fruiting branches and the fruiting branches with lengths of 5-15 cm were the greatest(57.00%).There was no significant correlation between the length or thickness of the parent branches and the number of fruits on the leafy branches.There was a significant positive correlation between the number of leaves and the number of fruits(r=0.998^(**),p=0.000).When the length of the leafy branches was 5-15 cm,the number of fruiting branches and the number of fruits reached a maximum,but there was no significant correlation between the length of the leafy branches and the number of fruiting branches or the number of fruits hanging.However,the number of fruiting branches and the number of fruits hanging were significantly positively correlated(r=0.998^(**),p=0.000).It can be concluded that the parent branches of the fruits of Crystal honey pomelo are mainly branches with lengths<30 cm and thicknesses<1.0 cm.The number of parent branches of fruit with leaves was mainly<15 cm and the number of leaves was<8.
