Evaluation of salinity tolerance in rice genotypes
Salinity is considered as one of important physical factors influencing rice (Oryza sativa L.) production. Knowledge of salinity effects on rice seedling growth and yieldcomponents would improve management practices in fields andincrease our understanding of salt tolerance mechanisms in rice. This study was designed to assess the role of Saltol QTL in regards to effects of salinity on plant gro...
متن کاملEvaluation of salinity response through the antioxidant defense system and osmolyte accumulation in a mutant rice
In order to assess the responses of Hashemi rice genotype and its advanced mutant line under salinity stress of 100 mM Sodium chloride (NaCl) for three and six days the shoot samples were taken for biochemical analysis. This experiment was performed in split plot based on randomized complete block design with three replications. The main factor was factorial combination of saline treatmen...
متن کاملfield screening of rice genotypes for salinity tolerance in mazandaran
to evaluate tolerance of rice genotypes (oryza sativa l.) to soil/water salinity and to utilize selected tolerant genotypes in rice breeding program and further agronomy and physilogical studies 56 rice genotypes have been evaluated. of which 40 rice genotypes from international rice research institute (irri) together with 16 selected tolerant rice genotypes have been tested in two separate exp...
متن کاملMechanisms of salinity tolerance.
The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, organ, and whole-plant level. Plant growth responds to salinity in two phases: a rapid, osmotic phase that inhibits growth of young leaves, and a slower, ionic phase that accelerates senescence of mature leaves. Plant adaptations to salinity are of three disti...
متن کاملGenetic Structure of Salinity Tolerance in Rice at Seedling Stage
The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshida's nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1...
