为了探索彩叶草株型矮化的化学控制，以其扦插幼苗为材料，通过对其株高及其细胞学特性硼究．发现叶面喷施15％多效唑可湿性粉剂800倍液和5％烯效唑可湿性粉剂7000倍液对彩叶草株型具有显著的矮化作用；叶面喷施50％CCC水剂400倍液，矮化效果不显著。细胞学观察表明，喷施多效畦和烯效唑。其茎秆表皮细胞长径显著变短，短径无显著变化；茎秆表皮毛显著变短，每个表皮毛的细胞豳显著减少：茎秆筛管直径显著变小。多效唑和烯效唑对其细胞伸长和分裂有抑制作用，限制了筛管营薪物质的运输，抑制了植株其他部位的生长，这些是使彩叶草株型矮化的主要原因。喷施CCC对彩叶卑无显著控矮化作用。但有相应...

In order to explore the chemical regulation of the plant type dwarfing of Coleus blumei, its cutting plantlets were used as the experimental materials in this research. Through studying its height and cytological characters of each treatment, we found that spraying 800-fold liquor of 15% Paclobutrazol wettable powder and 7,000-fold liquor of 5% Unlconazole （S3307D） on its leaves had significant dwarfing effect on it, 400-fold liquor of 50% chlormequat chloride （CCC） had not any. Cytological observation showed that after spraying Paclobutraz...
