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250~400μmol·m-2·s-1,最适光强为300~350μmol·m-2·s-1,300μmol·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。

Abstract: 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.
