Osmolytes changes for resistance in two cultivars of cotton (Gossypium hirsutum L.) Plants.
This study aims at the evaluation of physiological aspects of two cotton (Gossypium hirsutum L) cultivars, Siokra and Sahel to salin soil salinity [EC=12.3] collected from natural environment of Golestan province. Field tests in three stages, consist of two, four and six foliair seedlings were perfo...

| description | This study aims at the evaluation of physiological aspects of two cotton (Gossypium hirsutum L) cultivars, Siokra and Sahel to salin soil salinity [EC=12.3] collected from natural environment of Golestan province. Field tests in three stages, consist of two, four and six foliair seedlings were performed. In leaves of both cultivars, from 1st to 3rd salinity stress, increased Na+, Cl- concentrations noticeably , indicating that salinity resistance was not associated with the ability of the plants to restrict ions uptake and accumulation. During the three vegetative growth stages, from 1st to 3rd, CGR, NAR K+ and Mg++ uptake in both cultivars decreased but increased production of proline and was higher in siokra cultivar. Effect of high salinity, was accompanied by increasing soluble sugars and decreasing insoluble sugars contents, in both cultivars. The content of glycine betaine decreased partialy from two to six foliair stage. Results determined that cotton is among plants that having production and accumulation sterategies of proline-glycine betaine spontaneously. High salinity of soil increased the importance of proline and soluble sugars for resistance of plant and decreased nonsoluble sugar content during growth stages. |
