The combination effects of water stress and gibberellic acid (GA3) on physiological at tributes and nutritional status of maize (Zea mays L. cv., DK 647 F1 ) were studied in a pot experiment. Maize plants were grown in the control (well watered WW) and water stress subjected to treated both water stress and two concentrations of gibberellic acid (GA3 25mg?L-1, 50 mg?L-1). WS was imposed by main training the moisture level equivalent to 50 % pot capacity whereas the WW pots were maintained at full pot capacity. Water stress reduced the total dry weight, chlorophyll con centration, and leaf relative water con tent (RWC), but it in creased proline accumulation and electrolyte leak age in maize plants and appears to affect shoots more than roots. Both concentrations of GA3 (25and 50 mg?L-1) largely enhanced the above physiological parameters to levels similar to control. WS reduced leaf Ca2+ and K+ concentrations, but exogenous application of GA3 increased those nutrient levels similar or close to control. Exogenous application of GA3 improved the water stress tolerance in maize plants by maintaining membrane permeability, enhancing chlorophyll con centration, leaf relative water con tent (LRWC) and some macro-nutrient concentrations in leaves. |
