Study on Heat Resistance of Different Species of the Genus Sedum
Abstract Choosing the appropriate roof greening plants has important practical significance for the effect and application of roof greening.The high temperature plays an important role in many factors that affect the growth of plants, so good heat resistance is one of the essential conditions for the roof greening plants growing．In order to expore the heat resistance of roof greening plants and study the adaptability of the plant to high temperature environments，Sedum lineare’lvye’, Sedum lineare’yuanye’, Sedum sieboldii, Sedum spetabiles, Sedums armentosum Bunge, Sedum lineare ‘jinye’, Sedum reflexum, Sedum crassula.suitable for roof greening were as the test materials in the experiment．The relative water content ,Cell membrane and The content of soluble protein of above plants were tested at different heat treatment conditions．The results showed that:All the physiological and biochemical parameters of the plants participating in the experiment changed with the temperature and the differences were obvious,The results of leaf moisture,were roughly pided into three levels ,Sedum lineare ‘lvye’ showed best, Sedum sieboldii, Sedum lineare ‘yuanye’, Sedum spetabiles, Sedum crassula were worse, Sedum reflexum and Sedum lineare ‘jinye’ showed worst.The rank of cell membrance is Sedum crassula, Sedum reflexum, Sedum lineare ‘jinye’, Sedum lineare ‘yuanye’, Sedum lineare ‘lvye’, Sedum spetabiles ,Sedum sieboldii. The rank of the content of soluble protein of above plants is Sedum crassula, Sedum sieboldii, Sedum reflexum, Sedum lineare ‘jinye’ ,Sedum lineare ‘yuanye’, Sedum lineare ‘lvye’ ,Sedum spetabiles.
Key words Green roof; Sedum; Heat resistance; Relative water content; Electrical conductivity; the content of soluble protein
