Differences induced by drought stress at the physiological and anatomical levels in leaves of Sl and Sp plants placed in the same pot. Relative water content (A), chlorophyll fluorescence (B) and lipid peroxidation degree determined by MDA production (C) in leaves of Sl and Sp plants placed in the same pot, in control (C) and drought stress (DS, 4 days of withholding water). Transpiration rate (E) (D) and stomatal conductance (gs) (E) in C and DS. Stomatal density (F) and aperture (G) determined in the abaxial and adaxial leaf side of Sl and Sp plants, in C and DS. Results are expressed as mean ± s.e.m. Values with different letters are significantly different as determined by LSD (P < 0.05).
