Impacts of cold stress on stringy stonecrop and linear stonecrop in northern China

摘要：

Grasses in Orpine family have the characters of high stress tolerance and shallow root in morphology.Due to its high economic and ecological values, these grasses have been embodied in city greening and roof greening in recent years.So far, they have become the most important plants used in roof greening in China.However, the growth and distribution of these plants are limited by low winter temperature in Northern China (Zhao D.G,, 2005, Wang Y.F., 2006).In this study, the physiological and biochemical features of linear stonecrop and stringy stonecrop growing in controlled environment with different coldness gradient, so as to clarify the impact of cold stress on these two plants.This study aims to provide basic information about extending the linear stonecrop and stringy stonecrop on roof greening in Northern China.
