Table 2 Heritability of leaf parameters over periods

Variables	σ²_E	σ²_GE	σ²_Period	σ²_{GE × Period}	CV	H²
*Llength*	1430	19569	55510	4467	12	0.55
*LED*	928	4635	147004	1680	11	0.32
*LERmax*	0.03	0.37	18	0.09	10	0.53

Analyses of variance on leaf length (Llength), leaf elongation duration (LED) and maximum leaf elongation rate (LERmax) considering two periods (spring and autumn) on 'Herbie'. Are indicated: error (σ²E), genotypic (σ²GE), period (σ²Period) and genotype × period interaction (σ²GE × Period) variances, coefficient of variation (CV) and heritability (H²)
