Salinity is an important stress factor for crop plants.
In current research work, salt stress was applied to RX 770
hybrid maize plant. The
effects of additional supply of
Ca, K, and Mg salts to plants under
salt stress was evaluated using membrane permeability,
relative water content and proline concentrations as stress
indicators. Furthermore, effects of the treatments
on growth and on macro and micro nutrient concentrations in
shoots and roots were determined.
It was observed that supplemental Ca, Mg, and K had positive
effects on plant performance, by decreasing membrane
permeability and enhancing relative water contents (RWC)
under salt stress.
Key words: Proline, salt stress, membrane
permeability, relative water content. |
