Abstract
Eighteen poplar (Populus) clones, varying in growth capacity were grown in plastic containers under outdoor conditions. During the first year of growth their net CO2 exchange rate (NCER) was studied by infra-red gas analysis as a function of photosynthetic photon flux density (PPFD) under controlled environment conditions. Maximal NCER (under saturating PPFD) and the PPFD compensation point were significantly correlated with the first year's shoot length and hence with the above ground biomass production of the various clones.Keywords
