摘　　要：以"清风103"和"绿秀"两品种的青花菜为试材,采用25、50、100 mg·L-1的赤霉素喷施青花菜幼苗,研究不同浓度赤霉素对青花菜产量和品质影响。结果表明,50 mg·L-1浓度处理效果显著,100 mg·L-1处理显著降低青花菜的产量、花球紧实度及品质。With two varieties of broccoli Qingfeng 103 and Lvxiu as materials, GA3 of 25, 50, 100 mg· L^-1 was sprayed on them at young seedling stage to test the influence of GA3 of different concentration on yield and quality of the broccoli. The results showed that 50 mg· L^-1 treatment could increase the yield and tight degree best. However, 100 mg· L^-1 treatment could decrease the yield, tight degree and quality of broccoli obviously.
