Abstract
The design of an instrument for the simultaneous measurement of photosynthetically active radiation and red, far-red and blue light is described. The optical responses of the instrument closely match the action spectra of photosynthesis and some important photomorphogenic responses within the waveband of 400-800 nm. The design of a single instrument for the measurement of the quantum irradiance at 660 and 730 nm is shown. The application of these instruments to measurements in the field and a controlled environment is described.This publication has 1 reference indexed in Scilit:
