This study was conducted to investigate the effects of silver nitrate (AgNO(3)) on the flower quantity of cucumbers. The seeds used in this study, which was carried out in a plastic greenhouse, in the Gazi village of Antalya Province (Turkey) the during spring and autumn 2005 breeding periods, were 'Mostar F(1)' (designated as 'GND1') and 'Vesco Seeds Beith, Alpha F(1) (26.50 F(1))', designated as 'GND2' and those are the types having common production. The silver nitrate application was performed by the method of spraying on the growth tips of plants and 0, 250, 500, 750, and 1000 ppm silver nitrate doses were administered. The research was conducted with 4 repetitions having 5 plants in each repetition according to the Random Parcel Trial Pattern. In order to determine the effects of the applications, the effects of a number of female flowers and male flowers on generative characteristics of planting periods (spring and fall) were identified and the results were statistically evaluated. According to the results obtained in this research, AgNO(3) has led to die formation of male flowers (no male flower formation in control), has increased the number of male flowers, and has led to it decrease in the number of female flowers. The increase in the number of male flowers varied according to the periods (in 'GND2').
