Non-dormant and dormant seeds of Avena fatua metabolize (14)C-maltose in different ways: in non-dormant seeds, (14)C-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 (14)C-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.
野燕麦的非休眠和休眠种子以不同的方式代谢 (14)C-麦芽糖:在非休眠种子中,给胚乳施用的 (14)C-麦芽糖很容易在盾片中转化为蔗糖,并转运到胚中;在休眠种子中,从 (14)C-麦芽糖中合成的蔗糖很少,麦芽糖和葡萄糖往往在胚乳中积累。这表明,在萌发种子中,蔗糖的生物合成对于有效地将胚乳储备物质转运到胚胎轴是必不可少的。
