Abstract

Studies using field gas exchange measurements of photosynthetic carbon assimilation in the dominant tree species indicate that prolonged, near-freezing air temperatures and cool soil temperatures (<80°C) exert a strong inhibition during early summer. Soil drying appears to have potentially strong influences only at lower elevations while the stomatal response to air dryness is secondary during most of summer. -from Authors
