Greenhouse and Field Screening for Salinity Tolerance
Developing alfalfa varieties with tolerance to salinity requires a multi-prong research approach. Because of the complexity of the plant by environment interaction a combination of laboratory, field and greenhouse selection techniques is most effective in addressing this complicated trait. At Forage Genetics our breeding strategy for salinity tolerance includes high throughput laboratory and gr...
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 کاملRICE CULTURE Screening Rice Cultivars for Salinity Tolerance Using a Simple Laboratory Incubation
The research presented here highlights the use of a simple incubation procedure to evaluate the relative salt tolerance of currently available rice cultivars over a wide range of salt concentrations. Rice seeds were subjected to a series of salt solutions from 0 to 20 micromhos/cm, and the ability of each cultivar to germinate and develop to the S3 growth stage was evaluated. Germination values...
متن کاملSalinity Stress and Salt Tolerance
Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigour and crop yield (R Munns & Tester, 2008). Salinization affects many irrigated areas mainly due to the use of brackish water. Worldwide, more than 45 million hectares of irrigated land have been damaged by salt, and 1.5 million hectares are taken out of pr...
