Comparison of dependence of growth and sexual reproduction ofChlamydomonas geitleri on temperature and irradiance

Dependence of the growth of this alga culture on temperature displays a wide interval of temperatures (from 4 °C to 30 °C) and the dependence of the sexual reproduction only a narrow one (from 18 °C to 25 °C). The optimum temperatures for both the processes are not so different (round 23 °C). Dependence of both the processes on irradiance displays a wide interval of irradiances in both eases (from 4 W m^t-2 to 80 W m^t-2 PhAR and higher). The optimum irradiances for these processes are very different (approx. 50 W m^t-2 PhAR for the growth and approx. 10 W m^t-2 PhAR for the sexual reproduction) under the experimental conditions used.
