Abstract: 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.]
