摘要: 本文对松嫩碱化草地上羊草和星星草光合蒸腾特性的日变化进行了比较研究。二者的日变化规律相近,但星星草的光合能力和水分利用效率强于羊草。这是皇星草的耐盐碱能力优于羊草的原因之一。

Abstract: This paper has compared the diurnal variation of photosynthesis and transpiration character of Aneurolepidium chinense with that of Puccinellia tenuiflora in Songnen alkalited grassland. The regularitics of their diurnal variation are similar. But the photosynthetic ability and water use efficiency of P. tenuiflora is better than A. chinense. That is one of the reasons why saline-alkali tolerance of P. tenuiflora is better than A. chinense.

Key words: Aneurolepidium chinense, Puccinellia tenuiflora, Photosynthesis and transpiration character, Diurnal variation
