Mitochondria isolated by a zonal procedure from the cotyledons of germinating peas possessed a cyanide-resistant respiration. This respiration was virtually absent in mitochondria isolated during the first 24 hours of germination but thereafter increased gradually until the 6th or 7th day of seedling development. At this time between 15 and 20% of the succinate oxidation was not inhibited by cyanide. The activity of the cyanide-resistant respiration was also determined in the absence of cyanide. Relationships among mitochondrial structure, cyanide-resistant respiration, and seedling development are discussed.
用区带分离程序从发芽豌豆子叶中分离出的线粒体具有抗氰呼吸。这种呼吸在发芽后最初 24 小时内的线粒体中几乎不存在,但此后逐渐增加,直到幼苗发育的第 6 或第 7 天。此时,15%至 20%的琥珀酸氧化不受氰化物抑制。还在没有氰化物的情况下测定了抗氰呼吸的活性。讨论了线粒体结构、抗氰呼吸和幼苗发育之间的关系。
