Salt tolerance determination in advanced mutant line of rice (Oryza sativa) at seedling stage
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 6
Abstract
Salt stress imposes a major challenge to agricultural production, especially in arid and semi-arid regions. Rice (Oryza sativa) is the most salt-sensitive cereal crop. Therefore, the objective of this study was to investigate the effect of salinity on the plant growth trials and some osmoprotectants concentration in two rice genotypes (Hashemi parental and Hashemi advanced mutant line). For this purpose, seedlings were grown hydroponically under 0 (control), 5 and 10 dS m-1 NaCl stresses and different growth, qualitative and physiological traits were evaluated in three times including 6 h, 48 h and 1 w after salinity treatment. The results showed that salinity significantly reduced total fresh and dry weights as well as total chlorophyll content in both genotypes. Moreover, proline and trehalose content (as osmoprotectants) significantly increased in response to salinity stress. It was revealed that Hashemi advanced mutant line significantly delayed decreasing of total chlorophyll and had the highest proline and trehalose content as compared with Hashemi parental genotype. Overall, the Hashemi advanced mutant line that had the highest chlorophyll and osmoprotectants content identified as salt-tolerant genotype.
