摘　　要：使用不同浓度矮壮素(chlormequat,CCC)灌施蓝花棘豆,观测其对蓝花棘豆生长素(IAA)、赤霉素(GA)及花序生长的影响。结果表明:CCC具有降低蓝花棘豆IAA、GA含量水平的生理效应,可显著抑制蓝花棘豆花序生长,达到缩短花序节间长度的效果。To investigate the effects of CCC on the contents of IAA, GA and growth of inflorescence in Oxytropis cierulea, CCC with different concentrations were drenched. The results showed had physioLogicaL response to reduce the contents of IAA, GA, and could significantly inhibit the growth of inflorescence in Oxytropis coerulea, so the intemode length of inflorescence can be decreased.
