摘要
以不同品种芍药为试材,研究了芍药花芽分化各时期可溶性糖、淀粉、可溶性蛋白含量和过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)活性的变化。结果表明:早花品种‘粉玉奴’和‘大富贵’可溶性糖含量表现出降低-升高-降低的变化趋势,淀粉和可溶性蛋白含量在整个花芽分化时期变化幅度不大;晚花品种‘迟粉’和‘杨妃出浴’可溶性糖、淀粉和可溶性蛋白均表现双峰型变化曲线。4个芍药品种POD活性均呈现单峰型变化趋势,SOD和CAT活性随着花芽分化呈增强趋势。
Changes of soluble sugar,starch,soluble protein,POD,SOD and CAT activity in Paeonia lactiflora Pall.flower bud were investigated during flower bud differentiation on 'Fenyunu' 'Dafugui' 'Chifen'and 'Yangfeichuyu' Paeonia lactiflora Pall..The results were as follows,in early flower of 'Fenyunu' and 'Dafugui',soluble sugar content showed the trend of up after the first down and then down again,and starch and soluble protein contents changed slightly during the flower bud.In late flower of 'Chifen'and 'Yangfeichuyu',soluble sugar,starch and soluble protein showed bimodal curves.POD activity showed a single peak trends,SOD and CAT activity in the process of growing as the flower bud in all four varieties of Paeonia lactiflora Pall..
