Effects of photooxidation on membrane integrity in Salix nigra seeds

BACKGROUND AND AIMS: Salix nigra seeds are desiccation-tolerant, as are orthodox seeds, although in contrast to other orthodox seeds they lose viability in a few weeks at room temperature. They also differ in that the chloroplasts of the embryo tissues conserve their chlorophyll and endomembranes. T...
