摘要:
比较了10个品系的条斑紫菜(Porphyra yezoensis)藻体色素吸收光谱及在不同生长光强下的有效光化学效率(Yield).光谱测定结果显示,不同品系藻体吸收光谱基本一致,但峰值有所差异.试验品系中,杂交重组品系Y-H001的PE、PC和APC含量显著高于对照种质Y-W0401,分别高出41.4%、38.3%和43.2%;绿色突变体Y-gr01的3种藻胆蛋白含量及PE/PC显著低于对照,但Chla含量较Y-W0401高出28.2%;杂交重组品系H-Yy0502的PE/Chla、PC/Chla和APC/Chla显著高于Y-W0401.有效光化学效率测定结果表明,在不同的光强条件下,选育品系Y-J0201和诱变实验品系CM0305的Yield显著高于Y-W0401,而Y-gr01的Yield显著低于对照.本文对条斑紫菜不同品系藻体的光谱特性、色素组成及Yield进行了比较与分析.
