Tomato glasshouse trial summer 2015 IMPROVED


We are investigating the effects of plant biostimulants in different development stages of tomato plants. We will measure several photosynthetic parameters such as chlorophyll fluroescence Phi2 or chlorophyll content SPAD.


The One Protocol (Phi2, PSI, NPQ) II

The One Protocol to rule them all! Phi2, PSI, NPQt, combined!

Changes from previous The One protocol: - no longer outputs signal from the far red period, which simplifies the signal output for the user - changed distance between measuring pulses from 10,000 to 2,000 which improves measurement resolution - has an initial stabilization peri...

Chlorophyll content (SPAD) II

REQUIREMENTS: Firmware v0.39 or v0.40. Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness. Improvements over Chlorophyll content (SPAD): - performs 3 different spads at 3 intensities for thin and thick l...
