摘要： 研究了11个葡萄品种结果母枝粗度与新梢结实力的关系，结果表明，不同葡萄品种获得理想的新梢结实力，其结果母枝须有一适宜的粗度范围；结果母枝粗度与结果枝率、结果枝结果系数、新梢结果系数之间呈二次多项式回归关系；不同葡萄品种冬季修剪时结果母枝的选留应以不同粗度结果母枝的结实力为依据。

Abstract: In this paper,the relation between thick of grape fruit cane and shoot burlinss ability of 11 grape varieties has been studied.The conclution showed that to get hopeful shoot burliness ability different grape varieties have a different thick range of grape fruit cane.In a range of the thick of grape cane,the regressions between thick of grape cane and the rating of fruiting cane;thick of grape cane and shoot fruiting coefficient;thick of grape cane and fruiting cane fruiting coefficient were quadratic.The method of winter pruning for different cultuvars should relying on different burliness ability corresponding to different grape fruit cane thick.
