Abstract

In order to evaluate the physiology and biochemistry of sixth generation of rice mutant tolerant lines under salinity stress, an experiment was carried out as split plot arranged in a Completely Randomized Design with four replications. Main factor of experiment included three levels of Salt stress (0, 45, 75 mmol/l) and sub factor included 5 local rice Mutant lines contain Tarom Hashemi 1, Tarom Hashemi 2, Tarom Hashemi 3, Tarom Chaloosi and promising Nemat. The results of analysis of variance of interaction Salt stress and rice Mutant lines showed that affect of interaction on the studied traits was significant. In comparision with other lines, the results of experiment showed that Nemat under all levels of Salt stress had the highest content of Proline that was accompanied with decrease of protein activity in this line. Catalase and Gayacol peroxidase activity under stress condition increased and and there was fewer amount of Malondialdehyde and ionic leakage. Considering the positive and significant Correlation between dry weight of rice lines with Proline content (r = 0. 36 * ** ), Catalase (r = 0. 49 ), and Guaiacol peroxidase (r = 0. 51 ** ) and negative Correlation with Protein content (r =-0. 29 * ) and Malondialdehyde (r =-0. 36 * ) it seemed to suggest that the Nemat mutant could be as the most tolerant line, since the resistance mechanism of this line involves osmotic regulation and increasing the amount of proline amino acids through protein degradation and catalase enzymatic system, so these traits can be considered as basic mechanisms for tolerance to salinity.
