Abstract

To promote parthenocarpic fruit set in Deveci and Ankara local pear cultivars, different doses of GA₃, GA₄₊₇ and Promalin treatments were carried out.
The studies were conducted at the Fruit Research Station in the District of Lakes between 2008 and 2009. The obtained results varied by year, cultivar, and dose.
The highest rate of parthenocarpic fruits was recorded in 15 g ha^-1 of GA₃ treatment in Deveci but in 10 g ha^-1 of GA₄₊₇ treatment in Ankara.
The low rate of first quality fruits in the Promalin treatments indicates that they must be evaluated more carefully than the other treatments.
