Photosynthetic activity of control seedlings (C), after 5, 8 and 10 days of culture, and seedlings developed from embryos shortly treated with NO after imbibition (NO) after 5, 8 and 10 days of culture or shortly treated with NO control seedlings after 5 days of culture (5d+NO) and after 8 and 10 days of culture. Values are average ± SE of 3–4 replicated experiments. Asterisk significance from control at the same time of culture period at P ≤ 0.05
