The experiment was conducted to research the effect of light and temperature on maturation of Sargassum vachellianum receptacles and attachment, development and survival of Sargassum vachellianum embryos. The immature receptacles and fertilized eggs were respectively incubated in different temperatures (13, 18, 23, 28℃) and different irradiances (1 000, 4 500, 8 000 lx) for 12 days. The result was showed that he optimum temperature for receptacles release eggs was 23℃and light had not effect on receptacles release eggs.The optimum temperature and light for attachment, development and survival of Sargassum vachellianum embryos were 23~28℃and4500~8000 lx respectively. |
