Özet:

 

In this experiment, 100 ppm gibberellic acid (GA3) was applied to Memecik olive trees in the middle of June in the `on'
(bearing) year to research the effects on yield, reducing sugar amount, and endogenous hormones with the purpose of bearing fruit
regularly. The yield was 19.33 kg/tree in control plants and 17.33 kg/tree in GA3-treated plants in the `on' year. The yield was 7.17 kg/tree
in GA3-treated plants and 4.00 kg/tree in control plants in the 'off' year. While GA3 treatment was not very effective on the decrease of
fruit amount in the on'year,it∈creaseduitamount∈theon′year,it∈creaseduitamount∈theon' year, it increased fruit amount in the off' year. Moreover, GA3 treatment did not significantly affect total reducing
sugar amount, but it affected endogenous hormones. Total reducing sugar amount was determined at the 4% level in both years (on'andon′andon'
and off'). Glucose content was determined to be higher than sucrose and fructose in all plant organs and during flower bud formation
periods (induction, initiation, and differentiation). Furthermore, GA3 treatment increased abscisic acid, GA3, indole-3-acetic acid, and
zeatin levels during flower bud formation periods and in all plant organs (leaf, node, and fruit) in both years.
