Abstract
Non-dormant and dormant seeds of Avena fatua metabolize 14C-maltose in different ways: in non-dormant seeds, 14C-maltose administered to the endosperm is readily converted to sucrose in the scutellum and translocated to the embryo; in dormant seeds, little sucrose is synthesized from 14C-maltose, and maltose and glucose tend to accumulate in the endosperm. It is suggested that biosynthesis of sucrose is essential for effective transport of the endosperm reserve to the embryonic axis in germinating seeds.Keywords
