| Abstract: | The metabolic thermogenic curves of liver mitochondria isolated from the livers of Cyprinus Carpio vol and its parents were determined at 28°C by using an LKB‐2277 Bioactivity Monitor. The results indicated that their thermogenic curves are different The total heat output and total time of the metabolism of the liver mitochondria of the hybrid F1 (Cyprinus Carpio val) are more than those of its parents, and its maximum heat power is between that of the female parent and male parent. The relationship between their metabolic thermogenic curves and character of mitochondrial metabolism, and thermokinetics and the heterosis were analyzed and discussed. The character of the mitochondrial thermogenic curves reflected the physiologic character of heterosis. The microcalorimetric method proved to be a probable and sensitive tool for the assessment of heterosis. |
