| 摘 要： | 以鹰爪枫Holboellia coriacea、南五味子Kadsura japonica、尾叶挪藤Stauntonia obovatifoliola ssp. urophylla、山蒟Piper hancei等4种野生常绿藤本植物为试验材料,通过人工冷冻处理,对叶片的相对电导率、过氧化物酶(POD)活性和游离脯氨酸含量等3个生理指标进行了测定.结果表明:细胞膜透性表现为逐渐上升趋势;而过氧化物酶(POD)活性和游离脯氨酸含量则随着温度的降低呈现出先上升后下降的变化规律,低温下耐寒性强的种类能保持较高的POD活性.4种野生常绿藤本植物的抗寒性具有明显差异,其中以鹰爪枫抗寒能力最强,其次为南五味子和尾叶挪藤,山蒟抗寒能力最差.

| Abstract: | The elect rolyte leakage,activities of Peroxidase(POD)and the Proline of 4 species-Stauntonia obovatifoliola ssp.Urophylla,Holboellia coriacea,Kadsura japonica and Piper hancei were studied on cold resistance of them was given in this paper.The result showed that the electrolyte leakage,activities of POD and the Proline turned out to have different changes under different freezing temperature.The high cold resistant Pistachio variety showed the higher activities of POD.That cold resistance of these varietie... |
