Effect of Salt Stress on the Growth and Photosynthesis Rate of Bean Plants (phaseolus Vulgaris L.)
Year: 2008
Type: article
Abstract: The effect of salt stress оn some physiological parameters in young bean plants (cv. Lody) was studied under controlled conditions in a climatic room. The plants were grown in pots as hydroponic cultures in half-strength Hoagland nutrient solution. The plants were treated for 7 days with 50 and 100 mM NaCl and Na2SO4 , starting at the appearance of the fi rst trifoliate leaf unfolded. The salts were added to the nutrient solution. It was established that the applied doses of both salt types caused stress on the young bean plants, which found expression in the suppression of growth, photosynthesis activity and the plastid pigment content. The amount of proline in the tissues of the salt-treated plants was increased, while the cell water potential was reduced.
