| Salinity is a limiting factor fot growth and development, since it affects several physiological processes in plants. This trial aimed to assess the levels of photosynthetic pigments, betacyanins, lipid peroxidation and activity of antioxidant enzymes in Alternanthera philoxeroides under salt stress. Plants originated from an in vitro culture were acclimatized and irrigated with sodium chloride (0, 200 and 400 mM) for 30 d. The experimental design was completely randomized with a 3×2 factorial arrangement of treatments: three concentrations of NaCl and two plant tissues (stems and leaves). The experimental data was subjected to an analysis of variance and means where compared using Tukey test (p≤0.05). The levels of chlorophylls a, chlorophylls b and total... |
