Abstract
A field experiment was conducted with barley (Hordeum vulgare L. CV. BG 25) on sandy loam soil during 1978–79 at Haryana Agricultural University, Hissar (India). The results of the experiment revealed that the light intensity, temperature and stomatal conductance decreased, while the leaf water potential increased from flag to the lower leaves in the canopy. The irrigated barley showed a lower leaf temperature, higher leaf water potential and a greater stomatal conductance than unirrigated barley. The relationships between light intensity and stomatal conductance are discussed.
