赤霉素对君子兰花期调控的研究

应用赤霉素不同浓度和不同处理频率对君子兰品种"油匠"进行处理.结果表明:与对照相比各浓度赤霉素(GA3)处理对植株提高抽葶率、提早花期、促进叶生长都有明显作用.每天喷施1次200 mg/L赤霉素后植株的抽葶率高于其他处理,50 mg/L赤霉素可以明显促进君子兰的花葶生长.应用50mg/L和200mg/L赤霉素均可使君子兰提前21 d开花,经过50mg/L赤霉素处理后,花朵和果实数量多于其他处理.

Study on Control of Flowering with Gibberellin Treatment in Clivia miniata Regel

Clivia miniata Regel cv "Youjiang" was treated by gibberellin(GA3) with different concentrations and frequencies before flowering.The results showed that GA3 had remarkable effects on emerging of stalk,promoting flowering and enhancing growth of leaves comparing with control treatment.The emerging stalk percentage treated by 200 mg/L GA3 everyday was better than other treatments.The growth of stalk was obviously enhanced by 50 mg/L GA3 treatment.The flowering date was advanced 21 days by 50 mg/L and 200 mg/L GA3 treatment.The number of flowers and fruits treated by 50 mg/L GA3 were more than that of others treatments.
