摘要
以2年生的金叶风箱果、紫叶水蜡、紫叶稠李、红叶李、光辉海棠、王族海棠、金叶红瑞木和五角枫离体休眠枝条为试材,采用人工低温冷冻法,在低温胁迫条件下测定丙二醛含量、相对电导率、可溶性蛋白质含量等生理指标,以期为东北黑土区引种和园林应用提供理论基础。结果表明:8种彩叶树表现出了较强的抗寒性,能够抵御-35℃的低温,初步推断其抗寒能力:紫叶稠李、紫叶水蜡、光辉海棠、红叶李>金叶风箱果、五角枫、金叶红瑞木>王族海棠。
An experiment was conducted to study the physiological indexes including Malus sp.,Malus‘Royalty＇,Ligustrum obtusifolium ‘Purpureus＇,Prunus virginiana ‘Schubert＇,Prunus cerasifera var.atropurpurea,Physocarpus opulifolius ‘Lutein＇,Acer mono Maxim,Cornus alba ‘Aurea＇and so on eight color-leafed tree species.By using two-year-old detached dormant branches of the eight species as research objects,MDA content,relative electrical conductivity,soluble protein content were measured after being frozen at low temperatures.The results showed that,eight kinds of color-leafed tree showed strong cold resistance,could resist-35℃low temperature.The ability to resist cold was preliminarily inferred, Malus sp.,Ligustrum obtusifolium ‘Purpureus＇,Prunus virginiana‘Schubert＇,Prunus cerasifera var.atropurpurea〉Physocarpus opulifolius‘Lutein＇,Acer mono Maxim,Cornus alba ‘Aurea＇ 〉Malus‘Royalty＇.
