摘要: 对松嫩碱化草地上人工种植生长一至三年星星草光合蒸腾特性的日变化进行了测定。二年生和三年生星星草光合蒸腾的日变化规律比较一致, 而一年生星星草不同于二者.一年生星星草光合速率和蒸腾速率的日变化幅度大于二年生和三年生星星草, 其水分利用效率在一日中也均低于二年生和三年生星星草.

关键词: 星星草, 生长年份, 光合蒸腾特性, 日变化

Abstract: This paper concerns with the studies of the diurnal changes of photosythesis and transpiration of Puccinellia tenuiflora which was planted on Songnen alkalized grassland for one to three years. Diurnal changes of photosynthesis and transpiration of P. tenuiflora growing for one year is different from that growing two and three years. Diurnal changes range of photosynthesis rate and transpiration rate of P.tenuiflora growing one year is larger than that of growing two and three years. and it's water use efficiency is lower than that of growing two and three years.

Key words: Pucrinellia tenuiflora, Growing years, Photosynthetic and transpiration character, Diumal changes
