Long-range CO2-exchange measurements as a non-destructive method for determining crop growth


, : Long-range CO2-exchange measurements as a non-destructive method for determining crop growth. Revue de l' Agriculture 44(5): 913-922

An open multiple measurement system for CO2 gas exchange was developed for determining net photosynthesis and net C gain for a crop in a semi-controlled environment (plexi chambers in a PVC-clad tunnel structure) with different CO2 concentrations (350 and 650 p.p.m.) in ambient air.

The method was tested in the steppe and dry steppe zones of the Central Pre-Caucasus and Right-bank Pridnestrovie.
