Figure 2.

Variation in (A) trunk cross sectional area (TCSA) and (B) in fruit yield (dry matter), over the experimental period (2014–2018) in different olive cultivars (Arbequina and Frantoio) and treatments (Fr = fruiting, NF = non-fruiting). Each point is the average of the 9 trees that were non-destructively sampled until the end of the experiment. Bars denote standard errors. Different letters denote significant differences within each year. Averages were compared using the Student–Newman–Keuls test; probability level: ns not significant; ∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001.
