Glutathione-mediated changes in productivity, photosynthetic efficiency, osmolytes, and antioxidant capacity of common beans () grown under water deficit.

Globally, salinity and drought are severe abiotic stresses that presently threaten vegetable production. This study investigates the potential exogenously-applied glutathione (GSH) to relieve water deficits on plants cultivated in saline soil conditions (6.22 dS m) by evaluating agronomic, stability index of membrane, water satatus, osmolytes, and antioxidant capacity responses.
