a Results are expressed per L or kg of EVOO; Means within a line are mean values for each cultivar, year and crop stage. SEM: standard deviation of mean. Within each line, capital letters and lowercase represent statistical differences (P < 0.05) in each cultivar, Hojiblanca and Arbequina, respectively. n.s: P > 0.05; * P < 0.05; ** P < 0.01.
