e0“barley seeds of approximately 3 per cent, approximately 8 per cent and approximately 9 per cent moisture contents”
e5“The magnitude of oxic damage in seeds of a given moisture content remains unaltered following oxygenated post-hydration of seeds at 3 degrees C and 25 degrees C, but it registers a significant (P = 0.01) decrease if post-hydration in oxygenated water is carried out at 37 degrees C”

Other claims from this paper (8)
- Association Oxic damage at a 35 krad dose decreases as initial barley seed moisture rises from about 3% to about 9%.
- Observation Significant oxic damage occurs in barley seeds of all three moisture contents at 3 and 25 degrees C.
- Observation At 37 degrees C significant oxic damage occurs only in barley seeds of about 3% and 8% moisture.
- Intervention effect Oxygenated post-hydration at 3 and 25 degrees C leaves the magnitude of oxic damage unaltered.
- Association Oxygen-sensitive (An) sites in barley seeds react with oxygen about 6 to 8 times faster than they decay without oxygen at 3 and 25 degrees C.
- Association At 37 degrees C, oxygen-sensitive (An) sites in barley seeds react with oxygen only about 3 to 4 times faster than they decay without oxygen.
- Association Decay of An sites starts much earlier in very dry barley seeds (about 3% moisture) than in moister seeds (about 8% and 9%).
- Association The An-site fraction that decays rapidly without oxygen also reacts with oxygen more rapidly.
