植物生长延缓剂对两种绿篱植物矮化效应研究
Effects of plant growth retardants on Hibiscus rosa-sinensis L.and Carmona microphylla (Lam.) G. Don
摘要
Abstract
[Objective]The preseut study was conducted to study the effects of different kinds and concentrations of plant growth retardants on hedge plants and their influence on ornamental quality, and to provide scientific basis for reasonable applieation of the plant growth retardants and reduction of conservation costs. [Method]The effects of foliar spray of paclobutrazol (PP333) (50,100,150,200,250,300 and 400 mg/kg) and chlorocholine chloride (CCC) ( 100,200,300,400,500,600 and 800 mg/kg) on Hibiscus rosa-sinensis L. and Carmona microphylla (Lam.) G. Don was investigated at seedling and fully developed stages. [Result]The growth retardant CCC and PP333 significantly inthibited the growth of Hibiscus rosa-sinensis L, especially at the concentration of 400-500 mg/kg CCC, without affecting the plant's uniformity and vitality.PP333 retarded the growth of Carmona microphylla, and the effects were found to be the best at the concentration of 400800 mg/kg PP333, without affecting the plant' s uniformity. The CCC was not found to be suitable for Carmona microphylla plants and showed the worst effects. [Conclusion]The results revealed that spraying CCC @ 400-500 mg/kg on Hibiscus rosa-sin crnsis L. at developed stage and PP333 on Carmona microphylla twice inhibited the hedge growth without affecting the plant' s general development and ornamental quality, and may reduce the fieqnent cutting operations and the maintenance cost.关键词
