Fig. 6From: Quantification of spatial metal accumulation patterns in Noccaea caerulescens by X-ray fluorescence image processing for genetic studiesDistribution of shoot metal concentration for every 6th accession for respectively Zn, Ca, K, and Ni (a–d) as measured by ICP-AES. Comparison of normalized mean metal concentrations per substructure for all N. caerulescens accessions for respectively Zn, Ca, K, Ni, (e–h) derived from μXRF image analysis. Mean substructure metal concentrations are Z-score-normalized using the plant mean and standard deviationBack to article page
