摘要:

以上海市静安区巨鹿路和浦东新区黄杨路道路两旁的行道树悬铃木(Platanus acerifolia)为研究对象,采用化学调控的方法,研究ED药剂、调呋酸钠(美国)、杭州控果剂、国光絮必治、飞絮抑制剂和合畅6种化学药剂对悬铃木球果的影响,从而为悬铃木球果果毛的防控提供理论和技术依据。结果表明,经过化学药剂处理的悬铃木球果含水量下降,可溶性糖含量上升,SOD活性和POD活性升高。化学药剂使叶片颜色变淡;球果细胞正常代谢受到影响,糖类物质转化受阻,从而导致可溶性糖积累;球果含水量减少,表明球果的生长受到抑制,球果中果毛的质量减少,从而达到控制球果果毛的效果。在本实验的6种化学药剂中,合畅和ED药剂的防控效果最好。

Abstract:

Platanus acerifolia, a roadside tree on both sides of Julu road in Jing’an District and Huangyang road in Pudong New Area of Shanghai, was selected as the research object. The effect of six chemicals, included ED, tiaofuranate (USA), Hangzhou fruit control agent, Guoguang Xubizhi, Feixu inhibitor and Hechang, on the chemical regulation of cones of Platanus acerifolia were studied, which could provide theoretical and technical support for the prevention and control of P. acerifolia cone hairs. The results showed that the water content of P. acerifolia cones decreased after chemical treatment, the content of soluble sugar increased, and the activity of SOD and POD increased. The chemical agents could lead to light leaf color of Platanus acerifolia. The normal metabolism of cones was affected, and the transformation of carbohydrate was blocked, resulting in the accumulation of soluble sugar. The water content of cones decreased, indicating that the growth of the cones was inhibited and the cone hairs were reduced, thus the effect of controlling the hairs of the cones was achieved. Among the six chemical agents in this experiment, Hechang and ED agents had the best prevention and control effects.
