| 摘 要： | 选用多效唑PP333(Paclobutrazol)和矮壮素CCC(Chlorcholinchlorid)2种植物生长调节剂开展了3年生盆栽桂花(Osmanthus fragrans)的矮化效果研究.结果表明:浓度为1 500、3 000和6 000 mg/kg的矮壮素均使桂花新梢茎显著增粗(P＜0.05),浓度为1 500mg/kg的多效唑使桂花新梢长显著缩短(P＜0.05)；各浓度的生长调节剂基本使桂花花量增加,花期延迟.综合考虑盆栽桂花的生长及开花情况,多效唑的最适施用浓度为l 500mg/kg,矮壮素的适施用浓度范围为6 000 mg/kg. |

| Abstract: | The effects of paclobutrazol(PP333) and chlorcholinchlorid(CCC) were studied on dwarfing of 3-year potted Osmanthus fragrans.The results showed that CCC of 1500,3 000 and 6 000 mg/kg significantly enhanced the diameter of new shoots(P < 0.05),and PP333 of 1500 mg/kg significantly shortened the length of new shoots(P < 0.05).Plant growth regulators of each concentration tested enhanced and delayed the flowering of O.fragrans.The result demonstrated that the proper concentration of plant growth regulators applied for dwarfing of O.fragrans should be 1500 mg/kg for PP333 and 6 000 mg/kg for CCC. |
