摘　　要：用不含海水，含１／１５、２／１５、４／１５和８／１５海水的溶液处理碱谷（Ｅｌｅｕｓｉｓｎｅｃｏｒａｃａｎａ）１４天，分别测定其根、茎、叶的碳、氮、生物量和叶片的叶绿素含量。碱谷各器官的碳含量在１／１５海水处理时，均超过不含海水的对照组。根、茎的氮含量在４个处理中均高于对照组，但叶片的氮含量显著低于对照。在１／１５浓度的处理中，叶绿素含量比对照高。盐处理中叶片的生物量高于对照，根、茎的生物量则比对照低。碱谷是较好的牧草。Eleusisne coracana has been treated for 14 days respectively with ,1/15,2/15,4/15 and 8/15 of sea water solution. The capacities of carbon,nitrogen and biomass of the roots, stems and leaves were measured, and the chlorophyll content of the leaves of the species was analysed. The carbon content of the species in 1/15 sea water solution was more than that in the controlled solution. The nitrogen capacities of the roots and stems of the species in sea water solution were higher than thosee in the controlled solution, but unlike the root and stem, the nitrogen of the leaves was lower than that of the ccontrolled. At 1/15 sea water solution the chlorophyll of the species was more than that at the controlled conditions. The biomass of the leaves was higher than that of the controlled, meanwhile the biomass of the root and stem were lower than the controlled, in all the five treatments.
