| 摘 要： | [目的]筛选能抑制核桃营养生长、提高核桃产量的生长调节剂的种类与浓度。[方法]以云新早实核桃A、B、C、D4个品系为试材，对PP333和CCC2种生长抑制剂设置不同浓度进行核桃叶面喷施，分析PP333，和CCC不同浓度对核桃单果重、枝条充实度、单位芽数和单株核桃果数的影响。[结果]CCC喷施浓度为300mg／L时可显著降低核桃单果重量；施用PP333可显著提高坐果数量和单果重而增加单株产量，以500～1000ms／L喷施效果较好；喷施不同浓度P只。单位芽个数并无明显差异；喷施50mg／LCCC时，单位芽个数比对照降低18％；喷施100mg／LCCC时，枝条比重（1175kg／m3）较CK高13．9％；PP333，浓度为500mg／L时，枝条比重明显低于CK，其余各处理下，枝条比重差异不明显。[结论]该研究为生长调节剂在核桃上的应用提供指导。
