Dormant seeds of Avena fatua, which do not germinate when allowed to imbibe water, have a respiration rate only about 20% less than that of imbibed nondormant (after-ripened) seeds in the period before actual germination and are capable of synthesizing protein at a rate comparable to that of the nondormant seeds. An increase of protein synthesis is observed in nondormant seeds at the beginning of root protrusion. Autoradiography of seeds administered (3)H-leucine shows that protein synthesis occurs in the axis part of the embryo, the scutellum, the coleorhiza, and the aleurone layer. Dormancy in seeds is not a state of general inactivity; rather, it must be due to some specific metabolic block.
野燕麦休眠的种子在吸水后不会发芽，其呼吸速率在实际发芽前与吸胀的非休眠（后熟）种子相比仅降低约 20%，并且能够以与非休眠种子相当的速率合成蛋白质。在根伸出的开始阶段，非休眠种子中观察到蛋白质合成的增加。给予（3）H-亮氨酸的种子的放射自显影显示，蛋白质合成发生在胚轴部分、盾片、下胚轴和糊粉层。种子的休眠不是一种普遍不活跃的状态；相反，它一定是由于某些特定的代谢受阻。
