【摘要】 通过盆栽和管栽小麦试验分析，总根系、初生根和次生根的生长及根呼吸存在基因型差异。早中熟基因型初生根前期发育快，后期衰退也快；晚熟基因型则相反。但根量的多少并不直接影响产量。更多还原

【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.更多还原
