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。

关键词: 冬小麦, 基因型, 初生根, 次生根

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.

Key words: Winter wheat, Genotype, Primary root, Secondary root
