我们在一九七三～一九七四年研究中已证实:玉米杂种在群体一个体水平上的光合性能具有明显的优势。本试验的目的之一是在以往工作的基础上,进一步探索杂种优势是否在细胞器生化活性上也表现出来。这项工作在国外已有不少报导,但国内仍未见有正式报导。此外,М.Ф.ОВЧЙИИКОВА曾于1976年报导:玉米优势杂种的两个亲本叶绿体体外等比混合,在幼苗11日龄时其转能作用—希尔活性和光合磷酸化活性表现有互补增益效应,但同年中国科学院植物研究所在研究菠菜、甜菜两种不同作物之间叶绿体光合磷酸化效应
In our study from 1973 to 1974, we demonstrated that maize hybrids have obvious advantages in photosynthetic performance at one population level. One of the purposes of this experiment is to further explore whether heterosis is also demonstrated in the organelle biochemical activity on the basis of previous work. There have been many reports of this work abroad, but no official reports have yet been made in China. In addition, М.Ф.ОВЧЙИИКОВА reported in 1976 that the two parents of maize heterotic mixed in vitro and equiaxed in vitro, and their transdifferentiation at seedling age of 11 days showed a complementary gain effect on both Hill activity and photosynthetic phosphorylation activity , But in the same year, Institute of Botany, Chinese Academy of Sciences, studied the photosynthetic phosphorylation of chloroplast between two different crops of spinach and sugar beet
