摘　　要：以毛竹种子为材料,研究测定了种子萌发过程中部分生理指标的动态变化。结果表明:种子萌发期间,超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)的活性整体都表现出逐渐升高的趋势;丙二醛(MDA)含量呈逐渐下降趋势;可溶性糖含量先升高再降低;可溶性蛋白含量呈总体上升趋势。Determined the dynamic changes of physiological index of phyllostachys edulis during seed germination. The result showed that during seed germination of phyllostachys edulis, the activity of SOD, POD and CAT increased gradually; the content of MDA decreased gradually; at first, the content of soluble sugar increased, and then decreased;the content of soluble protein presented increasing tendency as a whole.
