Although the natural life history of the alga had been well understood, the factors influencing development of the tetraspore and carpospore remain poorly understood. In the perspective of seedling resources, the regulation of early development is crucial for the seedlillg nursing; therefore, it is necessary to understand the physiological influences during its early development. In this study, we studied the effects of temperature and irradiance on the early development of Chondrus ocellatus Holm under laboratory conditions. The released tetraspores and carpospores were cultivated at different temperatures （10-28℃） and irradiances （10, 60 μmol photons m^-2s^-1） with a photoperiod of 12L： 12D. The results indicate that both tetraspores and carpospores are tolerant to temperatures of 10-25℃, and have the highest relative growth rate at 20℃. Irradiance variances influenced the growth of the discoid crusts, and the influence was more significant with increasing temperature; 60 μmol photons m^-2s^-1 was more suitable than 10 μmol photons m^-2s^-1. The optimum temperature and irradiance for the development of seedlings was 20℃ and 60 μmol photons m^-2s^-1, respectively.展开更多
