用25、50和100 mg/L赤霉素(GA3)处理红地球果穗,均可显著促进果实生长,增大果粒,提高单果重,增加株产和产量,其中尤其以50 mg/L最为显著。但可溶性固形物含量却因GA3处理而明显下降,同对照相比,50 mg/L表现出极显著浓度效应,25和100 mg/L表现出显著浓度效应。

The treatment with different concentrations of Gibberellic acid(GA3) on the fruits of 慠edGlobe?grapes during growth had significant effects on promoting growth of fruits, enlarging fruits, enhancing weight of per fruit and increasing the yield GA3 50 mg/L showed best. However, GA3 treatments reduced significantly total soluble solids of fruits.
