| 摘 要： | 四种化学药剂处理的悬铃木，其冬季糖和氮含量均高于对照，春季则相反；并对新梢伸长有促进，对粗度有抑制效应；其中经ＧＡ３和乙硫氨酸处理的Ｃ／Ｎ比值增大，新梢成花量增加；乙烯利和２硫尿嘧啶处理的Ｃ／Ｎ比值减小，新梢成花量显著减少。从而为选用减灭悬铃木球果药剂提供理论依据

| Abstract: | Plantanus acerifolia trees were treated with four chemicals.The results show:The sugar and nitrogen content of the buds increased in winter and decreased in spring, accelerated lengthening of young branch and the diameter of young branch become smaller.The ratio of C/N of the buds and the number of flower buds on the shoot increased by the treatment of GA 3 and ethionine,and decreased by the treatment of ethyhene and 2 thiourcail.This experiment offers some suggestions for selection of cone abscission preparation for plane tree. |
