### Effect on Fruit Physiological, Organoleptic, and Phytochemical Parameters  
Based on the information provided by the farmers (plots were harvested by the farmers \"in hands\", and the total yield per plot was calculated), the mean yield of organically grown 'Bebecou' reached 46.7 kg per tree, while that of integrated managed trees was 58.5 kg. 'Diamantopoulou' trees grown under organic management produced 32.6 kg per tree, while under integrated practice, 40.2 Kg per tree (Table 1). Organically produced fruits of the 'Bebecou' cultivar presented higher values of mean fruit fresh weight, fruit diameter and length, pulp width, a ratio of diameter versus length, stone weight, pulp weight, and percentage of pulp per fruit fresh weight, but a lower value of fruit firmness (Table 1). There was not any significant difference concerning the percentage of dry matter as well as the concentration of \(\beta\)-carotene and \(\beta\)-cryptoxanthin. In 'Diamantopoulou', on the other hand, integrated produced fruits exhibited higher mean fruit fresh weight and diameter, higher pulp width, as well as higher stone and pulp weight (Table 1). There were not any significant differences, though, concerning the fruit length and firmness, as well as the pulp and dry matter percentage and the concentration of the two individual carotenoids determined. As far as the organoleptic characteristics of the fruit are concerned, the cultivation management exhibited a significant effect only concerning the ratio of TSS versus TA in 'Bebecou', where organically produced fruits exhibited greater values (Table 2). Integrated management seems to induce higher values of the CIELab b* parameter of the skin, as in both cultivars, it was found to be higher than that determined in organic fruits (Table 3). The Chroma index was also higher under integrated management concerning the fruits of the 'Bebecou' cultivar. The carbohydrate concentration of the fruit was not affected by the cultivation management in either cultivar, as can be seen in Table 4. Similarly, the concentration of the organic acids found in fruits of the 'Bebecou' cultivar was not affected by the cultivation practice employed, while only ascorbic acid concentration was higher under organic management in 'Diamantopoulou' (Table 5). \begin{table}
