Variations in superoxide dismutase (SOD) activity in primed and non-primed rice seeds under different storage conditions and storage durations. (A) Non-primed control, (B) Hydro-priming, (C) Osmopriming, (D) Spermidine priming. DAS, days after sowing; DAP, days after priming; NP, non-primed control; HP, hydro-priming; PEG, Osmopriming; Spd, spermidine priming; LT-V, the primed and non-primed seeds were stored under vacuum, low temperature condition; RT-V, the primed and non-primed seeds were stored under vacuum, room temperature condition; RT-A-LH, the primed and non-primed seeds were stored under room temperature, aerobic and low relative humidity condition; RT-A-HH, the primed and non-primed seeds were stored under room temperature, aerobic and high relative humidity condition. Error bar above mean indicate stand error (n = 4). Different letters denote difference between storage durations of a storage condition at the 5% level according to LSD test.
