Abstract

Abstract

The objective of the investigation of which this report is a part was to identify chemical elements, organic compounds, or metabolic processes which are associated with genetically controlled P accumulation in corn (Zea mays L.).

Two populations of corn, each with subpopulations selected for high and low P in ear leaves, were produced by randomly sib mating the F2 and five and six subsequent generations of an early maturing single-crossed hybrid and a late maturing single-cross hybrid. Each tingle-cross hybrid contained homozygous inbred lines previously characterized as contributors of low and high concentrations of P to other single-cross hybrids. In ear leaves, high P was associated with significantly higher, but not substantially different, concentrations of N and B. In seedling plants, grown for three weeks in a growth chamber, high accumulation of P was associated with higher concentrations of N and significantly higher concentrations of S, Ca, Cu, and B.
