Study on leaf dissection structure and drought resistance of four shrubs growing in desert steppe in Tsaidam
The leaf structure of Nitraria tangutorum,Ceratoides lateens,Kalidium gracile,Salsola arbuscula growing in the desert steppe of Tsaidam,Qinghai Province was studied by using the method of paraffin sheet formatting. The result indicated that the leaf dissection structure characters were closely related to the drought resistance. The drought resistant structure was found in the leaf of 4 shrubs. These 4 shrubs were suitable to be used in arid and semi-arid areas. six drought resistance indexes of leaf of four shrubs were measured and a comprehensive evaluation on drought resistance of them was provided through the method of subordinate function as well. The order of drought resistance capability of 4 shrubs was Nitraria tangutorum＞Ceratoides lateens＞Salsola arbuscula＞Kalidium gracile.
