研究杂种豫白桃及其双亲的一些生理过程的结果表明:杂种豫白桃各生育期的光合速率均高于双亲及对照品种,其叶绿素含量,除新梢开始生长期外,其它各生育期也均高于双亲及对照品种,而光合速率的动态变化和叶绿素含量的动态变化趋势是一致的。杂种豫白桃的过氧化物酶同工酶的酶带数目多于双亲,除有些酶带与双亲相似外,还出现双亲酶谱中所没有的新酶带。杂种豫白桃的果实含糖量和维生素C含量均高于双亲,而含糖量稍低于对照品种,但维生素C含量比对照品种高一倍多。 The results showed that the photosynthetic rate of hybrid peach peach and its parents were higher than those of parents and control varieties. The chlorophyll content of hybrid peach peach and its parents also showed a significant increase Higher than the parents and the control varieties, while the dynamic changes of photosynthetic rate and chlorophyll content trends are consistent. The number of peroxidase isozymes in hybrid peach peach was more than that in parents, except that some of them were similar to their parents, and the new ones were not found in the parental zymogram. White peach peach fruit sugar content and vitamin C content were higher than their parents, while the sugar content slightly lower than the control varieties, but the vitamin C content more than double the control varieties.
