摘要:
为促进苹果矮化自根砧大苗繁育，以一年生矮化自根砧苹果苗木‘礼泉短富’和‘维纳斯黄金’为试验材料，测定在不同浓度普洛马林处理下自根砧苗木的高度、茎粗、总分枝数、有效分枝数、有效分枝长度、有效分枝角度的差异，探究不同浓度普洛马林对自根砧苗木生长和分枝的影响，并筛选出最合适的喷施浓度。结果表明：对于‘礼泉短富’分枝情况最佳的普洛马林处理浓度为1 500 mg·L-1，对于‘维纳斯黄金’分枝情况最佳的普洛马林处理浓度为1 750 mg·L-1，处理后苗木总分枝较多，分枝长度和角度更适合整形修剪，苗木株高和茎粗也较为合理，能够达到理想的促分枝效果。
Abstract:
In order to improve the technology of apple seedlings breeding,oneyearold selfrooted rootstock apple seedlings,‘Liquan fuji’ and ‘Venus gold’,was used as experimental materials.Tree height,diameter,branch numbers,branch length and branch angles were measured to explore the influence of different levels of promalin trement on branching and growth of dwarf apple seedling and screening the optimal spraying concentration.The result showed that the best concentration of promalin treatment for ‘Liquan fuji’ was 1 500 mg·L-1,and 1 750 mg·L-1 was the best for ‘Venus gold’.There were proper branch numbers,branch length,angles,tree height and diameter for early shaping after treated with the best level of promalin.
