Analysis of root growth rate’s dependence on the holoploid DNA content was carried out on different plant species. Such dependence was found weakly negative in the primary roots of the dicot seedlings and in the lilioid adventitious root. The dependence was absent in the primary roots of the monocot seedlings. The relative elongation rate for the cortex cells of the dicot seedlings' primary roots also decreased with the increase in the holoploid DNA content. The data represent another example of a physiological process that is not directly related to DNA replication but whose rate depends on the genome size.

根系生长速度对全倍体 DNA 含量的依赖性

对不同植物物种进行根系生长速率对全倍体 DNA 含量的依赖性分析。在双子叶植物幼苗的初生根和百合不定根中发现这种依赖性是微弱的。单子叶植物幼苗的初生根中不存在这种依赖性。双子叶植物幼苗初生根皮层细胞的相对伸长率也随着全倍体DNA含量的增加而降低。这些数据代表了生理过程的另一个例子，它与 DNA 复制没有直接关系，但其速率取决于基因组大小。
