B-dependent growth behavior and analyses of B. napus cultivars grown in a LemnaTec cultivation system. (A) Left panel: Exemplary pictures of selected cultivars [IE (CR2262) = B deficiency-sensitive cultivar; E (CR2267) = B deficiency-tolerant cultivar] growing in B-deficient (-boron) or B-sufficient (+boron) zerosoil-substrate taken at days 5, 9, or 12 after sowing (DAS). Right panel: segmented plant images which are used for image analysis. (B) Principal component analysis (PCA) for 13 rapeseed cultivars based on recorded imaging-based growth parameters. Symbols indicate different B soil substrate conditions [Inline graphic = B-deficient (-), Inline graphic = B-sufficient (+) or Inline graphic = B-surplus (++) conditions].
