Root and shoot physiology of six German winter wheat cultivars released between 1895 and 2002

The dataset contains plant physiological measurements of six German winter wheat cultivars released between 1895 and 2002. Measurements were conducted during two growing seasons between the years 2022-2024 and contain detailed measurements of shoot and root properties. This includes measurements of leaf area index, specific leaf area, leaf level photosynthesis and stomatal conductance, leaf water potential, canopy transpiration, biomass of individual plant organs, CN ratios of the biomass, number of tillers, light extinction coefficient, canopy height, straw and grain yield, grain yield quality, root biomass, root biomass distribution, root hydraulic conductivity, axial and radial conductivity, root length, root aerenchyma proportions, root cortical cell number and diameter, metaxylem number and diameter, root stele diameter.
