Modelling the quantitative effect of oxygen on the ageing of primed celery seeds
The Plant Journal, Volume 122, Issue 1, April 2025.Significance Statement Effect of different oxygen levels on the shelf life of primed celery seeds at 20°C and 33% relative humidity. With primed celery seeds, stored between 16 and 45% RH, the oxygen level showed a log‐log linear relation with the rate ageing, with each halving of the oxygen concentration an extension of longevity by around 72 ...
