Throughout periods with out restriction, the pots ended up watered day-to-day at 100% of your WHC. Primed plants exposed to h2o deficit much better-preserved h2o position when compared to the naïve plants; glycine betaine is a crucial defense mechanism from water deficit in chirca; naïve plants have a higher focus of proline than plants underneath recurrent worry, demonstrating the larger require for defense against oxidative harm and desires greater osmotic regulation.
