Effect of zinc on the growth ,chemical composition and anatomical structure of barley (Hordeum vulgare L.C.M. var.) grown in saline medium

A factorial experiment was conducted in hydrponic culture to study the role of zinc to restrict salinity effects of morphological , anatomical and chemical features for barley plants . There was an increase in dry weight in presence of zinc with an increase in shoot content of Zn a compared with decrease in Na . On the other hand , there were an increase in the number of vascular bundles and vessel diameters in presence of zinc in saline growth medium .
