摘要
喷施GA3可在一定程度上促进青花菜的花芽分化进程,因而使花球的现蕾期、膨大期和采收始期相应提前,50mg·L-1GA3处理的最佳,产量和花球紧实度也增加,喷施100mg·L-1GA3的青花菜花球维生素C含量显著下降。
The experiment was carried out with different concentrations of exogenous GA3 spraying on broccoli (Brassica oleracea var. italica). The results showed that, the concentration of 50 mg·L^-1 GA3 could promote the flower-bud differentiation, advance the budding stage, rapid growing stage and initial period harvest, increase the yield and flower-ball compactness significantly. However, 100 mg·L^-1 GA3 decreased ascorbic acid of broccoli flower-ball obviously.
