  • Manganese absorption by barley roots

    Creator:
    Maas, E. V. (Eugene Vernon), 1936-
    Abstract:
    An investigation of Mn uptake by five-day-old excised barley roots revealed that a metabolically-mediated process was involved. In short-term experiments, the rate of Mn absorption was comparable to that of the macronutrient cations. Like other metabolically absorbed cations, the Mn absorption rate was a direct function of the ambient concentration...

  • Methods of evaluation, effects of intermating and results of one cycle of S₁ family recurrent selection in barley

    Creator:
    Mareck, James
    Abstract:
    The focus of this study was to determine if S₁ family recurrent selection might be successfully used for barley improvement. Objectives were: 1) to identify suitable methods of evaluating grain yield in small plots, 2) to study the effects of intermating on mean values and variances of selected agronomic characters,...
