采用不同的激素、贮藏方法和萌发温度进行道真润楠(Machilus dauzhenensis)种子发芽试验。结果表明,赤霉素(GA3)对道真润楠种子的萌发具有促进作用,其中200 mg/L GA3最利于种子的萌发,脱落酸(ABA)则抑制种子的萌发;道真润楠种子容易失水丧失活性,沙藏有利于种子的萌发;15~30℃是道真润楠种子萌发的最适温度。超氧化物歧化酶(SOD)和过氧化物酶(POD)的活性在道真润楠种子萌发过程中先升高后下降,丙二醛(MDA)含量变化则相反。

Different hormone treatments, storage methods and different temperatures was used to optimize germination conditions of Machilus dauzhenensis seeds. Results showed that GA3 could promote the germination of M. dauzhenensis seeds with the optimal concentration of 200 mg/L. ABA inhibited the germination. The seeds was easy to lose water so as to lose liveness. Sand storage was favorable for the germination of M. dauzhenensis seeds. 15~30℃ was the best germination temperature for the germination of M. dauzhenensis seeds. The activities of SOD and POD increased first and then decreased during the early periods of M. dauzhenensis seeds germination. The change tendency of MDA content was just opposite.
