Photosynthesis of tropical pasture plants i. illuminance, carbon dioxide concentration, leaf temperature, and leaf-air vapour pressure difference

Abstract

Carbon dioxide and water vapour exchange of attached, young, fully expanded leaves of tropical pasture species were measured in an open gas analysis system. The influence of illuminance, carbon dioxide concentration, leaf temperature, and leaf-air vapour pressure difference on net photosynthetic rate and carbon dioxide transfer resistances was studied. © 1971 ASEG.
