Respiration in the light, dark respiration, and leaf water status were monitored once a day in leaves of woody plants as seedlings dried during 7- to 10-day periods. Light respiration was estimated from an electrical analogue model of the response of net photosynthesis to ambient CO2 concentration and also by the rate of CO2 evolution into CO2-free air. Respiration in the light was found to increase with water stress in four dry-habitat species and to decrease with stress in four wet-habitat species. Dark respiration changes could not account for the different trends observed. When light respiration in dry-habitat plants under water stress was temporarily inhibited, net photosynthesis during recovery from water stress was reduced compared with controls for at least a week. This may indicate a protective role of light respiration in these plants when under water stress.

Nutritional Benefits

Water stress has become the most uncontrolled and unpredictable factor, which is continuously limiting production in crops. Legumes are the major source of protein and are well-recognized for their nutritional benefits as well as their impact on the sustainability of agricultural systems are well known. Leguminous crops are severely affected by water stress causing alterations in various development processes. Proper nutrient management helps in attaining economical legume yields from drought-prone lands. The protective role of potassium in plants suffering from water stress has been documented and it positively influences plant capacity to adjust water stress conditions. This review compromises the information on the water stress-induced harmful effects on legumes growth, nitrogen fixation, gaseous exchange and mineral uptake parameters and proposes appropriate management by potassium application to alleviate the severity of water stres on above mentioned parameters. Application of potassium proved to meet higher yield from legume on cultivation under low/residual soil moisture availability conditions.
