Seed germination and proline accumulation in rice (oryza sativa L.) as affected by salt concentrations
Plant cells accumulate praline as an osmoprotectant to conserve osmotic stability and prevent damage. However, the accumulation of proline may not be associated with tolerance to salinity.

| description | Plant cells accumulate praline as an osmoprotectant to conserve osmotic stability and prevent damage. However,
the accumulation of proline may not be associated with tolerance to salinity. This study considered the influences
of NaCl and Na2SO4 compositions, at different concentrations, on seed germination and accumulation of proline in eleven rice genotypes. Rice seeds were grown in petri dishes in the laboratory and treated with distilled
water as a control and NaCl and Na2SO4 (1:1 molar concentration ratio) at 2.5, 5.0, 7.5 and 10 dS m-1 electrical
conductivity for 14 days. The mean germination time (MGT) was positively affected by the increase in the
concentration of salt. Conversely, there was a negative relationship between germination index (GI) and salt
concentration. Shirodi, Fajr, and Shafag can be classified into salt tolerant group, while Tarom-e-Hashemi
was identified as salt susceptible, based on MGT and GI. Slight changes were recorded within dry weight
and water content of seedlings at different salt levels. The maximum accumulation of proline was observed
at 5 dS m-1 salt concentration. No relationship was established between the accumulation of proline and the
growth parameters. |
