摘要
长白木(Aralia continentalisKitagwa)种子具有休眠特性,自然条件下萌发困难,试验采用温度和药剂处理的方法研究打破长白木种子休眠促进萌发的方法。试验结果表明:变温处理比恒温处理更有利于长白木种子的萌发。在变温处理的条件下,GA3可以有效的提高长白木种子的发芽率和发芽势,在试验范围内其发芽率与发芽势随着处理浓度的增大而升高。
Aralia continentalis Kitagwa has dormancy property. It is difficult to break the dormancy during the natural conditions. This study investigated effect on the seed in dormancy-breaking process with different temperatures and chemicals. Resuits showed that fluctuating temperature was much more effect than low temperature on Aralia continentalis Kitagwa seed in dormancy-breaking process, meanwhile, GA3 play a vital role in the process under fluctuating temperature. The rate of seed germination and potential burgeon was increased by treatment with GA3.
