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 GA3 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.
