Analyses of variance on leaf length (Llength), leaf elongation duration (LED) and maximum leaf elongation rate (LERmax) for spring and autumn on 'Herbie' and for autumn on the core collection (Cc). Are indicated: error (σ²E) and genotypic (σ²GE) variances, coefficient of variation (CV) and heritability (H²)
