The experiment was carried out in three unheated plastic tunnels in 1998-2000. The aim of this study was observation on flowering dynamics and estimation of the effects of flower's heterostyly and two ways of flower pollination (self-pollination and using bumble-bee) as well as flower hormonization on the fruiting dynamics of three cultivars of eggplant: Black Beauty, Solara F1, and Epic F1. Eggplants began their flowering in June in three years of study. The most intensive flowering occurred in July 1998, and in August 1999 and 2000. Black Beauty produced the greatest number of flowers with medium-styled pistil, Solara F1 and Epic F1 - flowers with high-styled pistil. The first fruits were set in June from flowers with long-styled pistil. The best fruit setting for every combination was observed in July and August during the abundant eggplant's flowering. For all pollination ways, the greatest number of fruits developed from long-styled flowers. Plants, whose flowers were pollinated by bumble bees and hormonized, set a great number of fruits from flowers with medium and short-styled pistils
