Abstract :In this study, the effect of indole acetic acid insert ignore into journalissuearticles values(IAA); and/or a commercial enzyme mixture on the olive harvest was analyzed. IAA was produced by Gibberella fujikuroi . IAA insert ignore into journalissuearticles values(1500 and 3000 ppm); and/or the commercial enzyme preparation insert ignore into journalissuearticles values(1%); was mixed and applied to the olive trees before insert ignore into journalissuearticles values(3 weeks and 1 week); the harvest. The changes in protein, pectin and cellulose contents of fruits were determined monthly. While the cellulose and protein contents showed a decrease in 2 periods of 3 months insert ignore into journalissuearticles values(July-September and October-December);, pectin contents increased in the same period. IAA and/or enzyme applications did not lead to any significant changes in the cellulose and protein contents of the fruit insert ignore into journalissuearticles values(p>0,001);. However, the pectin amount in the trees where the enzyme application was performed before the harvest, showed a tendency to fall. The most convenient application with regard to the fruit and leaf fall was 3000 ppm IAA+1% enzyme application 3 weeks before harvest. While the fruit fall amount increased more when compared to the control and other groups with this application, the leaf fall decreased significantly.
