对农作物生长进行化学控制是现代农业大有可为的努力方向之一。近年来,国外开发了很多植物生长调节剂,因其优良的性能和应用价值,受到研究工作者的重视,并在生产上得到迅速推广和施用。本文将国外几种新型生长调节剂在果树上的应用情况简要介绍如下,以供参考。一、新型内源赤霉素抑制剂 1、PP_(333)(Paclobutrazol) PP_(333)是英国帝国化学工业公司(ICI)近年开发的具有高效、低毒的植物生长延缓剂和广谱性杀菌剂,通用名为Paclobutrazol(商品名为Cultar),化学名为:(2RS,
Chemical control of crop growth is one of the most promising directions for modern agriculture. In recent years, many foreign countries have developed a number of plant growth regulators, because of their excellent performance and application value, by the researchers attention, and in the production of the rapid promotion and application. In this paper, several new growth regulators in foreign countries on the application of fruit trees are briefly described below, for reference. A new type of endogenous gibberellin inhibitor 1, Paclitaxel (PP333) (Paclobutrazol) PP 333 is a highly effective and low toxicity plant growth retarding agent developed by British Imperial Chemical Industry Company (ICI) Agent, commonly known as Paclobutrazol (trade name Cultar), chemical name: (2RS,
