dc.description.abstract在实验室条件下,研究光照、温度、盐度及pH对龙须菜(Gracilaria lemaneiformis)和菊花心江蓠(G.lichevoides)N、P吸收速率的影响。结果表明,上述4个环境因子对这两种藻类的N、P吸收速率均有显著影响。其中,对龙须菜N吸收速率影响的适宜范围分别为:光照强度100~240μE.m-2.s-1,温度16~23℃,盐度25~35,pH 8.0~9.0;对P吸收速率影响的适宜范围分别为:光照强度80~200μE.m-2.s-1,温度16~23℃,盐度15~35,pH 8.0~9.0。而对于菊花心江蓠,N吸收速率影响的适宜范围分别为:光照强度120~300μE.m-2.s-1,温度23~33℃,盐度25~40,pH 7.5~9.0;P吸收速率影响的适宜范围分别为:光照强度100~240μE.m-2.s-1,温度26~33℃,盐度15~35,pH 7.5~9.0。
dc.description.abstractRed macroalgae Gracilaria lichenoides and G.lemaneiformis were selected as experimental objects,which have been cultured in a large scale in Fujian Province.The effects of four environmental factors—light intensity,temperature,salinity and pH—on uptake of nitrogen and phosphorus by the two macroalgae were studied under laboratory conditions.Ten light intensity grades(20μE·m~(-2)·s~(-1),40μE·m~(-2)·s~(-1),60μE·m~(-2)·s~(-1),80μE·m~(-2)·s~(-1),100μE·m~(-2)·s~(-1),120μE·m~(-2)·s~(-1),160μE·m~(-2)·s~(-1),200μE·m~(-2)·s~(-1),240μE·m~(-2)·s~(-1),300μE·m~(-2)·s~(1)),8 salinity grades(5,10,15,20,25,30,35,40),5 pH grades(7.5,8.0,8.5,9.0,9.5) and 6 temperature grades(8℃,12℃,16℃,20℃,23℃,26℃) were set up for G.lemaneiformis or 8 temperature grades(12℃,16℃,20℃,23℃,26℃,30℃,33℃,36℃) for G.lichenoides.The results show that all of the four environmental factors have significant effects on the uptake rates of N and P by the two algae.The most suitable ranges of the four environmental factors for the uptake rate of N by G.lemaneiformis are at light intensity 100-240μE·m~(-2)·s~(-1),temperature 16-23℃,salinity 25-35 and pH 8.0-9.0 respectively,and for the uptake rate of P by G.lemaneiformis,the most suitable ranges are at light intensity 80-200μE·m~(-2)·s~(-1),temperature 16-(23℃),salinity 15-35,and pH 8.0-9.0 respectively.The most suitable ranges of the four environmental factors for the uptake rate of N by G.lichevoides are at light intensity 100-240μE·m~(2)·s~(-1),temperature 16-23℃,salinity 25-35 and pH 8.0-9.0,respectively,and for the uptake rate of P by G.lichevoides,at light intensity 80-200μE·m~(-2)·s~(-1),temperature 16-23℃,salinity 15-35,and pH 8.0-9.0 respectively.
