The cytokinin production and transport from root to leaves is hindered under water stress causing leaf senescence due to the synthesis of hydrolytic enzymes. A part of stress effect may be linked to the regulation of osmotic solutes and maintenance of turgidity for stomatal conductance, photosynthesis and protein synthesis accompanied with reduced peroxidation of chloroplast and mitochondrial membranes in pearl millet under kinetin and cycocel treatments. |
