Counteraction of exogenous L-proline with NaCl in salt-sensitive cultivar of rice

The counteraction of exogenous L-proline at different concentrations with salinity (100 mM NaCl at sublethal concentration) were observed on germinating rice. Supplemented 30 mM L-proline was shown to be the most effective; at higher concentration it reduced seedling growth and K+/Na+ ratio. Thus 30 mM L-proline can alleviate the salinity stress in rice seedlings.
