2.6 Statistical analysis
Relative standard deviation was obtained, where appropriate, for all data collected. One-way analysis of variance (ANOVA) was evaluated using Statistica 10 software (StatSoft, Tulsa, OK, USA). The differences between the means of data for the two different cultivars at the three different harvesting stages were compared at the 5% level of significance (p < 0.05) using Tukey honest significant difference (HSD) test.
