Figure 2.

The number of rotten seeds determined after 7, 14, 21 or 40 days of accelerated ageing and the degenerative and morphological changes of embryos/seedlings after 7 days of the culture of embryos isolated from aged seeds (control) or embryos isolated from aged seeds and treated with NO. Values are the average of three independent experiments with 90 embryos in each (45 control and 45 NO treated). Homogenous groups were evaluated using Tukey’s test and signed as a–d (rotten seeds), a–c (rotten embryos/seedlings) and a–c (abnormal seedlings).
