Abstract:
The effects of irrigation water salinity on growth, chlorophyll contents, proline and nutrients accumulation and K/Na ratio in three walnut cultivars was investigated Three irrigation water salinity levels with electrical conductivities of 1,5, 3, and 50_dS/m and tap water as a control treatment were used in a randomized design with four replications Irrigation practices were realized by considering the weight of each pot Sodium, clor, prolin, K/Na and Ca/Na ratio of leaf were increased under salinity conditions But growth of plant and chlorophyll a, chlorophyll b content were decreased under saline condition There were significant differences between in irrigation water salinity levels in proline and chlorophyll a, chlorophyll b, Na content But there were not any significant differences in LRWC (%) Results showed that, regarding fresh shoot weight, dry shoot and root weight, there were significant differences between cultivars, but chlorophyll a, chlorophyll b, total chlorophyll, proline accumulation and leaf relative water content (LRWC) there weren’t any significant differences between cultivars Kaman 1 and Bilecik walnut cultivars showed higher accumulation of proline than Kaman 5 but was not observed significant difference between them.
