Mean values of three replicates marked with the same letter in the column do not differ significantly at a significance level of 0.05. Factor 1—harvest time (degree of nut ripeness). Factor 2—cultivar of nuts. Factor 1 × Factor 2—interaction between harvest time and the cultivar of nuts. ± standard deviation.
