SPAD difference in tillage treatments for C. Pepo


Curbita Pepo will be grown organically in four different treatments varying in cover crop placement, tillage, and mulching. The multispeq will be used as one of the tools to determine if these different treatments effect the relative chlorophyll or the plant grown within them.


Leaf Photosynthesis MultispeQ V1.0


Measures many photosynthesis-related parameters in <15 seconds, including:

  • Chlorophll Fluorescence: Phi2, PhiNPQ, PhiNO, NPQt, qL, LEF
  • Relative Chlorophyll: SPAD
  • Proton Motive Force: ECSt, vH+, gH+
  • Absorbance at: 450, 535, 605, 650, 730, 850, 880, and 940nm.
  • Leaf Thickness (in mm), angle, and cardinal direct...
