Abstract :
The current study agreenhouse research was designed to evaluate the reaction of fennel (Foeniculum vulgare Mill.) genotypes to salt stress (NaCl salinity) and Salicylic acid, to study of the proteome profile of leaves for identifying molecular pathway involved in salt stress tolerance. The study was designed as factorial experiment using a randomized complete block design in three replications. Treatments are included NaCl solutions at three levels (0, 100, 200 mM) as salinity stress, Salicylic acid at two levels (0, 0/5 mM) and five genotypes. Agronomic and physiochemical traits were included: fresh and dry weight of ariel plant and roots, plant height, root length, fresh and dry weight of total plant, chlorophyll a, b and carotenoids, total chlorophyll, Na+ and K+ content, K+/Na+ ratio, malondialdehyde (MDA), Hydrogen peroxide (H2O2) and Total soluble carbohydrate (TSC) of leaves. The analysis of variance revealed significant differences for main and interaction effects in examined traits. German and Moghan genotypes were expressed as the most tolerant and sensitive genotypes based on Arunachalam method, respectively.
