Synopsis

Viability loss during desiccation in the recalcitrant seeds of Castanea saliva, Aesculus hippocastanum and Quercus robur was accompanied by increased lipid peroxidation and build up of a stable free radical within their embryonic axes. We argue that the accumulation of the free radical marks the termination of a series of destructive events following the initiation of oxidative attack during moisture stress in recalcitrant seeds.
