Transpiration From Cotton Leaves Under a Range of Environmental Conditions in Relation to Internal and External Diffusive Resistances

Abstract

Tltudies on the transpiration of cotton leaves were made under a range of light intensities (3' 8, 7· 5, 15· 0, and 22·5 X 10'" erg cm-ll sec-I), temperatures (30, 35, and 40°C), and humidities (relative vapour pressures ranged from c. 0·4 to c. O· 8) at several low windspeeds, v, ranging from 0·6 to 3·1 em sec-I
