Post-ageing NO action in the apple embryos. The changes of the rate of the parameters analyzed in the experiment in which embryos isolated from seeds subjected to 21 days of accelerated ageing were fumigated with NO.

Parameter	Effect after NO Fumigation
Germination	↑
Metabolic activity	─
ROS level	↑
RBOH transcript levels	↑
MDA	─
RNA oxidation	↓
RNA nitration	↓
Protein oxidation	─
Protein nitration	─
Total antioxidant capacity	↑
SOD transcript levels CAT transcript levels	↑ ↑

Abbreviation: ↑ for increase, ↓ for decrease and ─ for no shift of the parameter in comparison to the control.
