Effects of Different Temperatures and Light Intensities on physiological characteristics of Didymodon vinealis

摘要

To obtain a better culture conditions and the optimum environmental factors for Didymodon vinealis (D. vinealis) in light incubator, effects of different light intensities (40, 120 and 240 μE·m~(-2)·s~(-1)) and temperatures (15, 20, 25, 30 and 35°C) on physiological characteristics of D. vinealis were studies under laboratory conditions. The results showed that Chla, MDA, soluble protein and soluble sugar contents of D. vinealis increased with the time and the light intensities increasing. MDA, soluble protein and soluble sugar contents got the minimum value at 30°C and 40 μE·m~(-2)·s~(-1). In summary, it was found that the optimum environmental factors for the growth of D. vinealis were the temperature 30°C and the light intensity 40 μE·m~(-2)·s~(-1).
