Genotypic variation in phosphorus efficiency between wheat cultivars grown under greenhouse and field conditions
Phosphorus (P) efficiency (relative growth), which is described as the ratio of shoot dry matter or grain yield at deficient P supply to that obtained under adequate P supply, was compared in 25 winter wheat cultivars grown under greenhouse and field conditions with low and adequate P levels in a P-deficient calcareous soil. Adequate P supply resulted in significant increases in shoot dry weigh...
متن کاملOrgan-specific phosphorus-allocation patterns and transcript profiles linked to phosphorus efficiency in two contrasting wheat genotypes.
Recent studies have identified genotypic variation in phosphorus (P) efficiency, but rarely have the underlying mechanisms been described at the molecular level. We demonstrate that the highly P-efficient wheat (Triticum aestivum L.) cultivar Chinese 80-55 maintains higher inorganic phosphate (Pi ) concentrations in all organs upon Pi withdrawal in combination with higher Pi acquisition in the ...
متن کاملRhizosheaths on wheat grown in acid soils: phosphorus acquisition efficiency and genetic control
Rhizosheaths comprise soil bound to roots, and in wheat (Triticum aestivum L.) rhizosheath size correlates with root hair length. The aims of this study were to determine the effect that a large rhizosheath has on the phosphorus (P) acquisition by wheat and to investigate the genetic control of rhizosheath size in wheat grown on acid soil.Near-isogenic wheat lines differing in rhizosheath size ...
متن کاملPhosphorus acquisition and internal utilization efficiency in tropical maize genotypes
The objective of this work was to determine the relative importance of phosphorus acquisition efficiency (PAE – plant P uptake per soil available P), and phosphorus internal utilization efficiency (PUTIL – grain yield per P uptake) in the P use efficiency (PUE – grain yield per soil available P), on 28 tropical maize genotypes evaluated at three low P and two high P environments. PAE was almost...
