摘    要:测定了50mg/L GA3和200mg/L 6-BA浸种后的朱砂根种子在萌发过程中酶活性的动态变化。结果表明:在萌发过程中,α-淀粉酶活性整体呈上升趋势,50mg/LGA3处理的活性最大;200mg/L 6-BA处理后的过氧化氢酶(CAT)和过氧化物酶(POD)活性最大,CAT活性是先上升后下降,露白到发芽阶段下降;POD活性一直呈上升趋势,在吸胀到露白阶段,其活性上升较平稳,而在种子露白后到发芽阶段开始迅速上升。

关 键 词:朱砂根种子  α-淀粉酶  过氧化氢酶  过氧化物酶

Abstract:The dynamic change of some enzymes activity were determined during seed germination of Ardisia crenata after soaked by 50mg/L GA3 and 200mg/L 6 - BA. The results showed that the activity of α-amylase activity increased gradually in proceeding of germination. The treatment which has the maximum α - amylase activity was soaked by 50mg/L GA3. The treatment which has the maximum catalase and peroxidase activity was soaked by 200mg/L 6 - BA. The activity of catalase increased in early of seed germination, then decreased; The activity of peroxidase has been on the rise. The activity of peroxidase rose steadily in the suction stage to protrusion, and rose rapidly in the protrusion stage to germination.
Keywords:Seeds of Ardisia crenata  α - amylase  Catalase  Peroxidase
