合作用-荧光测量系统GFS-3000应用和部分参考文献

        合作用-荧光测量系统GFS-3000应用和部分参考文献
     
     经过WALZ工程师的不懈努力,泽泉科技为广大用户带来了首创的GFS-3000附件——O2传感器,通过装配在GFS-3000上,可以通过控制条件来监测氧气变化环境下植物的光合荧光同步变化情况。另外该传感器可单独使用。
    光呼吸(Photorespiration)是所有进行光合作用的细胞(该处“细胞”包括原核生物和真核生物,但并非所有这些细胞都能运行完整的光呼吸)在光照和高氧低二氧化碳情况下发生的一个生化过程。它是光合作用一个损耗能量的副反应,过程中氧气被消耗,并且会生成二氧化碳。如果光呼吸发生在进行光合作用的生物中,那么光呼吸会抵消约30%的光合作用。因此降低光呼吸被认为是提高光合作用效能的途径之一。    
    气体交换技术测量光合速率由于自身技术原因无法排除光呼吸的干扰。为了更准确地反映光合速率,可以通过降低氧气浓度,抑制光呼吸来实现。为此,我们提供了氧气传感器,结合控制实验,来监测外界进入仪器气路的氧气情况,以减少光呼吸对光合的影响。单独使用该传感器时,具有更广泛的应用范围。
