摘　　要：光环境对螺旋藻的生长有着一定的影响,本试验为探究LED红蓝绿光质光照模式对螺旋藻生长、产量、形态建成以及关键产物的积累的影响。利用LED的光谱可调性,设置了单红光400μmol/m^(2)·s^(-1)、红蓝光400μmol/m^(2)·s^(-1)、500μmol/m 2·s-1(R∶B=4∶1)、红蓝绿光400μmol/m^(2)·s^(-1)(R∶B∶G=15∶4∶1;R∶B∶G=15.5∶4∶0.5)五个处理组,对螺旋藻培养6 d后进行采收,比较不同处理下螺旋藻形态建成、生物产量、叶绿素a和藻蓝蛋白的含量的影响。结果表明单红光处理的藻丝形态正常,物质产量、叶绿素a含量和藻蓝蛋白含量皆为最高,分别为0.88 g、11.99 mg/g、1.98 mg/g。蓝光和绿光的加入不同程度的影响了螺旋藻的物质积累,但绿光的加入使藻蓝蛋白有下降趋势,而使叶绿素a含量有所增加。The light environment has a certain influence on the growth of spirulina.This experiment is to explore the influence of the LED red,blue and green light mode on the growth,yield,morphogenesis and accumulation of key products of spirulina.Using the spectral adjustability of LEDs,five treatment groups were set up:single red light at 400μmol/m ^(2)·s^(-1),red blue light at 400 and 500μmol/m^(2)·s^(-1)(R∶B=4∶1)and red blue green light at 400μmol/m^(2)·s^(-1)(R∶B∶G=15∶4∶1;R∶B∶G=15.5∶4∶0.5).Spirulina was harvested after 6 days of cultivation,and the effects on the morphogenesis,biomass,chlorophyll a and phycocyanin content of spirulina under different treatments were compared.The results showed that the morphology of filaments treated with single red light was normal,and the substance yield,chlorophyll a content and phycocyanin content were all the highest,which were 0.88 g,11.99 mg/g and 1.98 mg/g respectively.The addition of blue light and green light affected the accumulation of spirulina in different degrees.However,the addition of green light made the phycocyanin show a downward trend,while increasing the chlorophyll a content.
