摘要
柳叶藓光合作用的最适水温为 15℃ ,光合作用的适宜光强为 2 5 0～ 4 0 0 μmol·m-2 ·s-1,最适光强为 30 0～ 35 0 μmol·m-2 ·s-1,30 0 μmol·m-2 ·s-1时光合速率达最高峰。柳叶藓的光补偿点随温度的升高而升高。呼吸速率与水温呈正相关。
This paper studies the photosynthtic and respiratory characteristics of Amblystegium serpens , which lives in fountain.The optimum water temperature is 15℃ and the optimum light intensity is 250～400μmol·m -2 ·s -1 ,needed for A. serpens photosynthesis.The photosynthtic rate is the highest at 300μmol·m -2 ·s -1 .The light compensation point increased with water temperature,with 10,50,54 and 59μmol·m -2 ·s -1 at 10,15,20 and 25℃ respectively.Respiratory rate of A. serpens has a positive relationship with water temperature.
