NaCl Salinity affected differentially the different organs of plant (roots, stems and leaves) of broad bean genotypes (Vicia faba L cv. Wardy) cultivated in
.pots (5Kg) the data revealed that the stem was the most salt tolerant whether root was the most salt sensitive organ and leaves was intermediate, accordingly the salt tolerance of the three organs ranked according to the following trend (stem> leaf>root).
The leaf area of special interest in this study that the trend of leaf area went parallel to the fresh and dry matter yield of leaves which indicated that the two processes were closely linked under salt stress.
The effect of salt stress on photosynthetic pigments (Chl.a, Chl.b and carotenoids)was also varied that while Chl.a decreased slightly the Chl.b increased slightly and carotenoids were intermediate.
Phytohormonal treatments (IAA (0.2mM) or salicylic acid (0.5mM) enhanced in most cases all of these parameters which was more pronounced in salicylic acid treated plants than IAA treated plants at most salinization levels.
