Abstract

For evaluation of SALINITY stress effect on some ecophysiological traits including leaf scorch severity, CHLOROPHYLL INDEX, amount of FREE PROLINE, relative water and leaves IONIC CONTENTs of selected genotypes of East Azerbaijan ALMOND population (Prunus amygdalus B.) and accessibility of promising tolerant genotypes among them the experiment completely randomized design with three replicates and five SALINITY treatments including: (0, 25, 50, 75 and 100 mmol l-1 NaCl) was carried out. SALINITY treatments were applied to two- year- old seedlings planted in regional typical soil. Results showed CHLOROPHYLL INDEX and RELATIVE WATER CONTENT were decreased by the increase in the amount of salt significantly and linearly but FREE PROLINE was increased under this condition (P£1%). Leaf analysis results also showed Na+ and Cl- contents were increased significantly with SALINITY (P£1%) whereas Mg2+ and Ca2+ contents had a deceasing trend but non significant. K+ content of the leaves was influenced by different SALINITY levels irregularly, but Na/K. and Na/Ca ratios were increased when the SALINITY level was increased. This research determined that leaf scorch threshold in experimented genotypes was in relation with an accumulation of Na+ between 9 to 11 mg g-1 dry weight.
