Growth and Physiological Difference of Primary and Secondary Roots in Wheat Genotypes

doi:10.3321/j.issn:1000-7091.1999.01.005

Abstract

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
