We evaluated the effects of saline stress on soluble proteins, lipid peroxidation (TBAR), chlorophyll a, chlorophyll b, &amp;#946;-carotene, violaxanthin, and proline in Paulownia imperialis and Paulownia fortunei plants grown in vitro. When the propagated plants reached a determined size, they were transferred aseptically to WPM culture medium containing different sodium chloride concentrations (0, 20, 40, 60, 80, and 160 mM) and were sampled at 15 and 30 days. Proline content was determined at 30 days after transfer only. Protein concentration significantly decreased with the highest salt levels in P. imperialis compared to controls in which no sodium chloride was added. In both P. imperialis and P. fortunei, lipid peroxidation significantly increased at...
