Seed germination and cuttage of Adina rubella
-
摘要: 为了探索细叶水团花Adina rubella的繁殖方法，采用正交试验设计，研究温度、赤霉素（GA3）质量浓度及处理时间对种子萌发的效果，以及扦插基质、ABT生根粉质量浓度及其处理时间对扦插枝条成活率的影响。结果显示：①GA3质量浓度对细叶水团花种子萌发影响最大，其次为温度，处理时间影响最小；最佳处理组合为，15~20 ℃下，在300 mgL－1GA3溶液中浸泡60 min，萌发率达75.6%。②基质对细叶水团花枝条扦插成活率影响最大，其次为枝条浸泡时间和ABT质量浓度；最佳处理组合为扦插基质为泥炭∶泥沙（体积比）=1∶1， ABT质量浓度为50 mgL－1，浸泡时间为60 min，成活率达（91.00.7）%。表5参19Abstract: To explore reproduction methods of Adina rubella, an experiment with an orthogonal design was conducted to determine the effects on seed germination with treatments of concentration of gibberellic acid （GA3） （A1: 100 mgL－1, A2: 200 mg L－1, and A3: 300 mg L－1）, treatment times （B1: 30 min, B2: 60 min, and B3: 90 min）, and temperature （C1: 15－20 ℃, C2: 20－25 ℃, and C3: 25－30 ℃）. Then, survival rate of cuttings was tested with treatments of cutting medium （A1: peat, A2: peat : sediment = 1:1, and A3: sediment）, concentration of ABT （B1: 50 mgL－1, B2: 100 mgL－1, and B3: 200 mgL－1） and treatment time （C1: 30 min, C2: 60 min, and C3: 90 min）. Results on seed germination showed that （1） GA3 concentration had the largest effect followed by temperature, and then treatment time. The optimal treatment was GA3 of A3, time of B1, and temperature of C1 with a germination rate of 75.6%. （2） For survival rate of cuttings, cutting medium had the greatest effect with the effects of immersion time and ABT concentration following. For this the optimal treatment was cutting medium- A2, ABT concentration- B1, and time- C1 with a germination rate of 91.0%. ［Ch, 5 tab. 19 ref.］
