Physiological Activity, Nutritional Composition, and Gene Expression in Apple (<i>Malus domestica</i> Borkh) Influenced by Different ETc Levels of Irrigation at Distinct Development Stages

Managing irrigation efficiently is paramount given the uncertainty in the future availability of water and rising demand for this resource. Scheduled irrigation significantly influences vegetative growth through improving crop physiology and nutrient uptake and use efficiency. Influence of different...

The concentration of Ca and Mg content in leaf tissues are greatly influenced by the optimum supply of water during the early growth stages of apple growth.
