摘要
利用复性电泳技术 ,对小麦品种三叶期前后过氧化物酶 ( POD)酶谱进行分析 ,结果表明 :小麦三叶期前后 POD的分子量均在 35k D以上 (含 35k D) ;三叶期以前叶片中的 POD活性比三叶期以后的弱 ;小麦三叶期前后绿叶中始终含有 30 0 k D、52 k D、4 7k D、39k D、37k D5条活性较强的酶带 ;在不同的生育阶段绿叶中 POD的种类和活性均有显著变化 .
The peroxidases of green leaves at trefoil stage were analyzed with renaturation electrophoresis. The results show: The MWs of peroxidases are all above 35kD (including 35kD). The activity of peroxidase before the trefoil stage is weaker than later. The five kinds of stronger peroxidases of 300kD, 52kD, 47kD, 39kD and 37kD always exist in the period of trefoil stage. The kinds and activity of peroxidases have distinguished changes at different growth stages.
