摘  要:
为研究藤本植物在低温胁迫下植株的生理、生化变化,对中华常春藤(Hedera nepalensis)、南蛇藤(Celastrus orbiculatus Thunb.)、藤本月季(Rosahybrida Climbing Roses)、云南黄馨(Jasminummesnyi Hance)、扶芳藤(Euonymus fortunei)5种藤本植物在不同低温处理下植物叶片的细胞膜透性、超氧化物歧化酶(SOD)活性和可溶性蛋白质含量进行测定.结果表明:随着温度的降低,胁迫时间的延长,5种植物的叶片细胞膜透性增加,SOD活性增大,可溶性蛋白质含量呈上升趋势;试验表明,这3种变化指标可用于5种植物叶片的抗寒性测定;在这5种植物中,扶芳藤较抗寒,云南黄馨、藤本月季、中华常春藤抗寒性居中,南蛇藤抗寒性最差.

摘  要:
To improve the use of lianas in urban river landscape,physico-chemical changes in five different lianas,such as Hedera nepalensis,Celastrus orbiculatus Thunb.,Rosahybrida ClimbingRoses,Jasminum mesnyi Hance,Euonymus fortunei were analyzed during low temperature stress.Membrane permeability,superoxide dismutase(SOD) activities and soluble protein contents in leaves of these five plants were measured at different temperatures.The results showed that membrane permeability,SOD activity and soluble protein contents all increased as the temperature lowered and the time prolonged,which indicated that the three factors could be used as the indexes to leaf cold resistance of the five plants.Among the five plants,E.fortunei showed the highest cold resistance,while C.orbiculatus showed the lowest cold resistance than the others.
