B_9、CCC都能抑制矮牵牛的营养生长,使株型矮化、枝叶紧凑、开花部位集中、防止倒伏,明显地提高了观赏价值,尤以B_9的效果更佳。B_91500～6000ppm能使营养生长期植株矮化61.5～67％,盛花期矮化40.5～46.4％,叶片增厚29.0～41.9％,栅状组织增厚11.0～22.9％,叶重增加1.1～12.5％,叶绿素含量提高9.2～20.2％。CCC2500～10000ppm能使营养生长期植株矮化18.5～50.5％,盛花期矮化2.9～23.3％,叶片增厚25.8～35.5％,栅状组织增厚13.2～16.3％,叶重增加0～12.5％,叶绿素含量提高13.4～27.7％。B_93000ppm与1500ppm可明显增加开花数量,而B_96000ppm与CCC2500～10000ppm增花作用不明显或略有抑制现象。
B_9 and CCC all inhibited the vegetative growth of petunia, making plant type dwarf, compact foliage, centralized flowering parts and preventing lodging, obviously improving the ornamental value, especially the effect of B_9. B_91500 ~ 6000ppm can dwarf plant 61.5-67% in vegetative growth stage, dwarf 40.5-46.4% in blooming stage, leaf thickened 29.0-41.9%, palisade tissue thickened 11.0-22.9%, and leaf weight increased 1.1-12.5% , Chlorophyll content increased 9.2 ~ 20.2%. CCC2500 ~ 10000ppm can make vegetative growth dwarfing 18.5 ~ 50.5%, dwarfing flowering 2.9 ~ 23.3%, leaf thickening 25.8 ~ 35.5%, rachis thickening 13.2 ~ 16.3%, leaf weight increased 0 ~ 12.5% , Chlorophyll content increased 13.4 ~ 27.7%. B_93000ppm and 1500ppm can significantly increase the number of flowering, and B_96000ppm and CCC2500 ~ 10000ppm flowering effect is not obvious or slightly inhibited.
