| 摘要 | Sargassum muticum is one of the most abundant and conspicuous native macroalgae species on the northern coasts of China. It often forms large-scale seaweed beds in subtidal zones. This investigation was designed to understand the intraspecific genetic relationships of this alga based on samples collected from four northern coastal sites of China, and to evaluate gamete release and growth capacity in laboratory conditions. The nuclear internal transcribed spacer 2 (ITS2) sequences of 16 samples from four locations were identical. Based on cox3 gene and partial rbcLS operon sequences, intraspecific genetic variability was detected with three and two ribotypes, respectively. Temperature, not irradiance, was shown to significantly affect gamete release and fertilization. Elevated temperature and irradiance enhanced the growth of germlings and vegetative branchlets. Maximum growth rate of germlings was detected at 18-24 degrees C and an irradiance of 60-100 mu mol photons/(m(2).s). Under ambient conditions (12-25 degrees C and 60-125 mu mol photons/(m(2).s)), relative growth rate of young branchlets could reach 7.5%/d.; Sargassum muticum is one of the most abundant and conspicuous native macroalgae species on the northern coasts of China.
