Figure 8
Effect of exogenous putrescine (Put) on the content of endogenous free, bound and conjugated PAs in the thylakoid membranes of cucumber plants grown in nutrient solutions with or without 75 mM NaCl for 7 days.
Each histogram represents a mean ± SE of three independent experiments. Different letters indicate significant differences between treatments (P < 0.05). The data were taken on the third leaves (numbered basipetally), after the final salt treatment (75 mM NaCl) for 7 days. Cont, 0 mM NaCl + 0 mM Put; Put, 0 mM NaCl + 8 mM Put; NaCl, 75 mM NaCl + 0 mM Put; NaCl+Put, 75 mM NaCl + 8 mM Put.
