- BİTKİ VERİMLİLİK ANALİZ CİHAZI -OS1P
KLOROFİL II FLORESANS TEKNİĞİ İLE BİTKİLERDE VERİMLİLİK ANALİZİ YAPMAKTADIR
ÖLÇÜLEN DEĞERLER:
Y(II): Quantum Photosynthetic Yield (F/Fm’) Fo: Minimum fluorescence Fm: Maximal fluorescence Fv: Variable fluorescence Fv/Fm: Maximum photochemical efficiency Fv/Fo: More sensitive stress detector than Fv/Fm, but does not measure plant efficiency. Fm’: Maximal fluorescence under steady state conditions Fs: Fluorescence signal prior to saturation pulse (F’) NPQ: NPQ, Y(NPQ), Y(NO) lake model parameters according to Hendrickson calculations supplied as standard. Customer may alternatively purchase the Puddle model or Kramer Lake Quenching models. Ft: Current fluorescence readout ETR: Electron transport rate (with optional PAR sensor) PAR: Photosynthetic Active Radiation (with optional PAR sensor) T: Leaf temperature (with optional PAR sensor) rETRmax: Leaf photosynthetic capacity Ik: Minimum saturation level RLC: Rapid light curves ?: Initial slope of line at low PAR values, relating ETR to PAR. Used as a measure of quantum efficiency. Im: Intensity at rETRmax
