摘要:
通过对光合色素及叶绿素荧光测定,研究了条斑紫菜“苏通2号”自由丝状体在不同光照度下光合生理特征。结果表明,随着光照度的上升,样品藻红蛋白、藻蓝蛋白和别藻蓝蛋白含量均呈下降趋势,且高光照度处理组要显著低于低光照度处理组,叶绿素a的变化与藻胆蛋白相似。藻红蛋白/叶绿素a(PE/Chl a)和藻蓝蛋白/叶绿素a(PC/Chl a)比值随处理光照度上升而下降,但别藻蓝蛋白/叶绿素a(APC/Chla)未有明显变化。高光照度处理组样品最大量子效率(Fv/Fm)显著低于低光照度处理组,且较低光照度处理组样品实际量子效率(ΔF/Fm′)日变化高于高光照度处理组。快速光曲线参数中,初始斜率(α)、最大相对电子传递速率(rETRmax)均随光照度上升而下降,而半饱和光照度(Ik)差异不明显。光化学猝灭(qP)参数随光照度上升而降低,而非光化学猝灭(NPQ)结果与之相反。本研究提示,条斑紫菜“苏通2号”丝状体在较低的光照度下表现出活跃的生理状态,并能通过调节吸收光能分配以适应较高的光照度,这为该品种自由丝状体高效培养的环境设定提供基础参考。
