园林植物抗寒性鉴定指标的分析

Cold Tolerant Identification Index Analysis for Landscape Plants

抗寒性鉴定是园林植物抗寒研究中的重要工作之一,选择客观的鉴定方法是鉴定园林植物抗寒性强弱的关键。为准确、快捷鉴定园林植物的抗寒能力以及抗寒物种及品种的筛选提供参考,阐述并比较分析了园林植物抗寒性测定的主要方法,包括形态学观测、含水量测定、原生质膜透性测定、保护酶系统测定和渗透调节物质测定。

The cold resistance identification is one of the important works in the landscape plants hardiness research.Choosing the objective identification method is the key to identify the cold hardiness of landscape plants.The main methods to determine the cold resistance for landscape plants were compared and analyzed,including morphological observation,moisture determination,plasma membrane permeability determination,protective enzyme system determination and osmotic adjustment substances determination.It could provide reference for identifying the cold resistance of landscape plants and the selecting of the cold resistant species and varieties accurately and quickly.
