Canopy to root ratio of young olive trees for different olive cultivars (Arbequina and Frantoio) and treatments (Fr = fruiting, NF = non-fruiting), calculated in 2016 and 2018. Data are averages of 3 plants. Bars denote standard errors. Averages within each year were compared using the Student–Newman–Keuls test; the probability level (ns = not significant; ∗∗∗ = P < 0.001), is indicated in the legend below the respective year. Different letters denote significant differences within each year.
