“…However, salt stress begins to have toxic effects including changes in the ion balance and a critical concentration of Na + in the cytoplasm (14,24). Concurrently, different species, regardless of their level of drought and salt tolerance, vary in the degree of plasmolysis of cells and normal cellular activities may be restored (14,25). However, the most complete characterisation of stability / sensitivity of the species studied only provide a complex assessment of various parameters of the leaf blades and root system.…”

The results of the complex analysis of different wheat species tolerance to drought stress in vivo at different levels of organization as well as in vitro on callus cultures, which was conducted, are presented. The objects of research are as follows: species of wheat-T. monococum L. (A u ), T. dicoccum Shuebl. (A u B), T. polonicum L. (A u B), T. aethiopicum Jakubz. (A u B), T. macha Dek.et.Men. (A u BD), T. compactum Host. (A u BD), and T. aestivum L. (A u BD). The methods of this research are physiological, biotechnological, and cytological. The focus was on nonspecific reactions of cereals to osmotic stress, and species-specific changes according to growth and anatomical and photosynthetic parameters which depend on studied species ploidy were shown. It was shown that results of testing of plant tissues in vivo and in vitro are comparable. It demonstrated the criterions for selection of drought-tolerant forms. Optimal selection criteria were identified, and more drought-resistant wheat species were identified.

“…Salinity stress like other characteristics also affects on plant's root, leaf and stem attributes (Poljakoff-Mayber, 1975;Hameed et al, 2010). Root is the first organ which experiences the earliest salinity stress (Solomon et al, 1986;Terletskaya et al, 2015).…”

Plants are subjected to numerous abiotic stresses which adversely influence on their growth, metabolism and productivity. Among them, salinity stress is one of the most detrimental factor for plants growth and yield.In present review, we describe the impacts of salinity stress on numerous characteristics of wheat crop including morphological (plant height, root length, number of leaves, leaf area, root hairs count) and physiological (water relations, stomatal conductance, photosynthesis and chlorophyll content) are some of them. Other characteristics like biochemical, molecular and anatomical aspects have also been addressed. It can actually be not easy to recognize which characteristics are the mainly imperative ones for salts-tolerance in a wheat system.For easiness to this complexity, authors suggest the graphs generation to assist in showing relationships among the traits especially biochemical and molecular characterizations that are of prime consideration to modify existing or/and develop new varieties.
