Study the effect of Salinity on accumulation of ions in seven cotton cultivars Gossypium hirsutum L

A pot experiment was carried out to study the effect of different soil salinity on physiological characteristics of cotton plant (Gossypium hirsutum) and determining of resistant cultivars as factorial arrangeed by completely randomized design with 3 replications. Cotton cultivars were including Coker *349, Opal, Bol 539, N200, Acalas sj2* seland, Sahel, Sepid as first factor and levels of salinity in consist of nonesaline and saline, 0.6, 16.5ds/m as second factor. The results showed that effect of salinity on, Na, K, Ca2, Mg2, Cl-, was significant at 1% probability and.Between cultivars, K, Cl-, was significant at 1% probability and Na, Ca2, was significant at 5% probability and Mg2, wasnt significant. With regard of total masured characteristic it refered that, Sepid and Sahel cultivars were more tolerant to salinity stress.
