摘　　要：通过正交试验研究了温度和盐度对刺枝鱼栖苔(Acanthophora spicifera)生长及其光合色素的影响,以探明刺枝鱼栖苔生长的最适温度及盐度条件。结果表明,刺枝鱼栖苔生长的适宜温度范围为20—30℃,最适温度为25℃,在此温度条件下其相对生长率(RGR)最大为4.33%;适宜盐度范围为15—35,最适盐度范围为20—25,随盐度的继续升高,刺枝鱼栖苔RGR呈下降趋势。温度和盐度对刺枝鱼栖苔光合色素(chl a、Car、PE和PC)的影响显著,高盐胁迫能明显降低刺枝鱼栖苔光合色素的含量,而高温能促进其藻胆蛋白的合成与积累。The effects of temperature and salinity on growth and photosynthetic pigment of marine red alga Acanthophora spicifera were investigated by orthogonal design. Results reveal that it was suitable for the growth in a range of 20—30℃ and 15—35, best at 25℃ and 20—25, in temperature and salinity respectively. The double factors showed significant effects on the photosynthetic pigment （chl a, Car, PE and PC） of A. spicifera. High salinity stress decreased distinctly the contents of photosynthetic pigments while high temperature promoted the synthesis and accumulation of PE and PC.
