摘要
[目的]通过研究矮化砧木对甜樱桃生长特性的影响,探讨甜樱桃矮化砧木在生产中的应用效果。[方法]用1、5、7号3种接穗分别嫁接了G18、G25和S 3种砧木(共9种组合),于第2年冬季测量了干周、总枝量和平均枝长,调查了短枝率和成花率。[结果]9种穗砧组合中,1/G18的干周较大,亲和性较好,并且短枝率和成花率均最高。以G18为砧木的其他组合亲和性也较好。[结论]砧木在甜樱桃矮化、提高短枝率和成花率方面具有重要作用。
[ Objective ] The research aimed to evaluate the effects of dwarfing rootstock on the vegetal characteristics of sweet cherry. [ Method] Scions from three varieties （No. 1,5 and 7） were grafted on three species of rootstocks （G18, G25 and S） respectively. Bole perimeter, mean shoot length, proportion of short shoot and proportion of flower bud were investigated in next winter. [ Result] Bole perimeter of 1/G18 was longer with 18.5 cm. And the proportion of short shoot and flower bud were both the highest in total 9 combinations. Other characteristics of G18 were better than that of other combinations. [ Conclusion] Rootstock played an important role in dwarfing sweet cherry, improving percentage of short shoot and proportion of flower bud.
