Abstract
Unimbibed seeds of cabbage (Brassica oleracea L. Capitata group, cv. Early Jersey Wakefield, were artificially aged at 40°C in 100% relative humidity for up to 20 days. Aged seed and non-aged seed were imbibed in H20 at 25° in the dark up 0, 1, 4 or 16 hours, after which concentrations of Ca, Mg, Mn, K, and Cl in the whole seed were determined by neutron activation analysis. Concentrations of Ca, Mg, and Mn did not significantly change during the imbibition period for either control or aged seed. However, as the aging time increased, seeds lost increasing amounts of K and Cl during imbibition. The concentration of K decreased continually throughout the imbibition period in both aged seed and control seed. The decrease was significantly greater in the aged seed. Cl, too, was lost during imbibition and like K, the greater loss occurred in aged seed.
