### Classification of Treatments, Cultivars, and Farms Based on the Raw Data Collected  
The principal component analysis of all raw data resulted in 15 principal components (PC) with eigenvalues above 1, while the first 2 components accounted for only 39% of the total variability in the original data. \begin{table}
\begin{tabular}{l l l l} \hline \hline
**Parameter** & **Integrated** & **Organic** & **Significance** \\ \hline \hline  & \multicolumn{2}{c}{**Bebecou**} & \\ \hline
**Total phenolic compounds** & 0.31 & 0.28 & ns \\
**Total o-diphenols** & 0.12 & 0.096 & *** \\
**Total flavanols** & 0.006 & 0.013 & * \\
**Total flavonoids** & 0.098 & 0.089 & ns \\
**DPPH** & 0.12 & 0.08 & ns \\

Total phenolic compounds are expressed in mg equiv. gallic acid g\({}^{-1}\) FW, total o-diphenols in mg equiv. caffe acid g\({}^{-1}\) FW, total flavanols in mg equiv. catechin g\({}^{-1}\) FW, total flavonols in mg equiv. catechin g\({}^{-1}\) FW and DPPH and FRAP are expressed in jmol. equiv. Tolox g\({}^{-1}\) FW._

Table 6: Effect of cultural management on fruit phenolic compound concentration and antioxidant capacity of the two apricot cultivars. Nonetheless, to elucidate the situation, the two PCA graphs are presented, even with such a low cumulative variability explained. The two cultivation practices assessed in the present experiment could not be fully distinguished based on the principal component analysis performed on all raw data collected, irrespective of the cultivar (Figure 1). \begin{table}
