Abstract: In order to give a better understanding the factors which influenced the seeds germination and to optimize the germination system, the effects of different plant growth regulators with different concentration, as well as different soaking time and temperature on seeds germination were conducted. The results showed that temperature was the crucial factor dominating germination, and the optimal temperature was 25℃. The highest germination rate of 73.3% was achieved after soaking in 0.02% NAA for 24 h and cultivated under 25℃. Soaking in low concentration of IAA, NAA or GA3 for 12 h could highly enhance the germination rate.
