| 摘 要： | 通过盆载和管栽小麦试验分析，总根系１初生根和次生根的生长及根中呼吸存在基因型差异。早硎一根前期发育快，后期衰退也快；晚熟基因型则相反，但极量的多少并不直接影响产量。

| Abstract: | Genotypical difference existed in the growth and respiration of total and primary and secondary roots by analysis of pot and tube experiments. The primary roots of early middle mature genotypes grew quick in the early stage, and senescence quick in the late stage; but late mature ones showed inversely. The amount of root did not directly influence the grain yield. |
