Tukey HSD pairwise comparison for root morphology, anatomy and shoot-related traits at 95% confidence level showing the difference between group means (second column) and the adjusted p-value (fifth column) for all root traits (first column) between the two groups of barley offspring lines. Besides, the average value and standard deviation of the values for ISR42-8 and Golf are illustrated. The stable is split in two main windows—one for field, the other for hydroponic experiment. *Organic always as first value—negative values are related to smaller in organic lines. See Table 1 for trait description.
