PP333(多效唑)是一种高效、低毒 的植物生长延缓剂,与内源或外源赤霉素 均有拮抗作用,对多种果树无论土壤施用 或叶面喷洒,都能明显抑制营养生长,使 树体矮化。据许维纯等在桃树上试验(19 86),可看到叶面积变小,叶色浓绿,经 测定叶内叶绿素含量增高,光合强度增 加。[1]为探明PP
PP333 (PP333) is an efficient and low toxicity plant growth retarding agent, antagonistic to endogenous or exogenous gibberellin. It can significantly inhibit vegetative growth of many fruit trees regardless of soil application or foliar spraying, Dwarf the tree. According to Xu Weichun and other peaches in the test (19 86), we can see smaller leaf area, dark green leaves, the determination of leaf chlorophyll content, increased photosynthetic intensity.
