Phytochrome control of cellulase activity in Datura ferox L. seeds and its relationship with germination

The influence of phytochrome on endosperm softening and cellulase activity was studied on light-stimulated Datura ferox seeds. Endosperm softening preceded the earliest signs of radicle protrusion, and there was good correlation between the % of seeds with soft endosperm at 48 h after R and germinat...
