Abstract
Changes in growth and anatomical structure of vascular tissues in stem, root and leaf of safflower plants grown in NaCl and CaCl2 solutions having different osmotic potentials (ΨS from 0 to -0.9 MPa) with addition of 0, 10 and 20 mg dm-3 zinc were studied. Shoot and root lengths, fresh and dry masses and fresh/dry mass ratio were lower in salt-stressed plants compared to unstressed plants. Salinity induced structural changes in stem, root and leaf tissues; few xylem vessels with smaller size were noticed in stressed plants. The higher concentration of Zn improved growth especially in roots and enhanced xylem formation in comparison to stressed plants grown at the same osmotic potential without Zn. Zn also protected xylem distructure by salinity in leaves.
