During three years (2008-2011), from August to February, in 15-day intervals, were taken samples of fruit and leaves on cv. Ulliri i Zi, in over 10 randomized olive trees in Gerbllesh, Tirana. The analysis consisted in statistics estimates according diagnostics and multivariate correlation analysis for: fruit weight, percentage of oil, the humidity in leaves and fruit, acidity and peroxides no. too determinate physiological correlations. After bonding, fruits have increased rapidly until endocarp sclerification 17.3 mg/day. In August and September fruits and leaves are dehydrated (withered), and fruit’s growth was lower, 11.1 mg/day. Reduction of water in the fruit to 50% correlates linearly with the leafy content 55%, (r?=0.92). As a result, the photosynthesis was reduced, and therefore oil daily assimilation rate was 0.11%, in linear correlation with leafy moisture (r? =0.86). After strong dehydration a part of leaves and fruits were falling down. By recreating of turgor, growth of mesocarp’s fruit was 17.1 mg/day, at the same time as oil synthesis in fruit 0.18 %/day, (r?=0.87). At the beginning of December fruit’s weight=2.31g (maximum weight) and oil percentage of 19.2% considering the biological correlation. After dehydration of fruit as a result of further maturation, and decreased weight 18.6 mg/day, while the % of oil has resulted in an increase of 0.1%/day and between these phenomena has been negative correlation (r? =-0.17). At this stage the humidity of the leaves is normal while the value of acidity, and peroxides no. has been associated with the maturity of the fruit.
