利用石蜡制片法,对青海省柴达木荒漠草原4种灌木唐古特白刺(Nitraria tangutorum)、驼绒藜(Ceratoides latens)、里海盐爪爪(Kalidium gracile)、木本猪毛菜(Salsola arbuscula)叶片的解剖结构进行了观察和分析.结果表明,4种植物叶片的解剖结构性状与耐旱性有着密切的关系,4种植物的叶片均具有旱生的形态及结构特征,适宜于我国干旱半干旱地区生长.对4种灌木叶片的6个抗旱指标栅栏组织厚度、海绵组织厚度、栅栏组织厚/海绵组织厚、表皮细胞厚度、表皮细胞外壁厚度和气孔下陷深度进行了测定,运用模糊数学隶属函数值法对4种灌木的抗旱性进行综合分析表明,4种灌木抗旱性大小顺序依次为:唐古特白刺>驼绒藜>木本猪毛菜>里海盐爪爪.
利用石蠟製片法,對青海省柴達木荒漠草原4種灌木唐古特白刺(Nitraria tangutorum)、駝絨藜(Ceratoides latens)、裏海鹽爪爪(Kalidium gracile)、木本豬毛菜(Salsola arbuscula)葉片的解剖結構進行瞭觀察和分析.結果錶明,4種植物葉片的解剖結構性狀與耐旱性有著密切的關繫,4種植物的葉片均具有旱生的形態及結構特徵,適宜于我國榦旱半榦旱地區生長.對4種灌木葉片的6箇抗旱指標柵欄組織厚度、海綿組織厚度、柵欄組織厚/海綿組織厚、錶皮細胞厚度、錶皮細胞外壁厚度和氣孔下陷深度進行瞭測定,運用模糊數學隸屬函數值法對4種灌木的抗旱性進行綜閤分析錶明,4種灌木抗旱性大小順序依次為:唐古特白刺>駝絨藜>木本豬毛菜>裏海鹽爪爪.

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.
