Abstract
Accelerated aging predisposed seeds to imbibition injury. Slowing the rate of hydration prevented the loss of germinability due to imbibition injury. Germinability of accelerated aged seeds (50 hours) was increased from 10 to 90% by controlling the rate of imbibition. Slow hydration also prevented seed electrolyte leakage. This may indicate that cell membrane permeability or rupture was a major factor contributing to the loss of germinability after aging.Reversal of the effects of aging (repair) was accomplished by slowly inbibing and then redrying seeds (priming). This treatment lowered steep water conductivity by a factor of 2 to 5. Priming also increased the per cent germination of low vigor seeds. The mechanism of this reversal was probably metabolic because it depended on temperature, seed moisture, and treatment duration.Priming doubled the survival of seeds in the accelerated aging vigor test. The ;rejuvenation' was accepted as evidence for metabolic repair. Since the ;vigor' of seeds was increased by priming, metabolic repair probably included other subcellular components as well as the plasma membrane.
