The experiment was carried out in a three unheated plastic tunnels in 19982000. The aim of this study was to estimate the effects of flower' s heterostyly and two methods of flower pollination (self-pollination and using bumble-bee) as well as flower hormonization on the flowering and fruiting of three varieties of aubergine 'Black Beauty', 'Solara F1 and 'Epic F1" The analysis of results showed that the "eggplants formed more flowers in object with self-pollination and flower hormonization than those pollinated by bumble-bee. Regardless of the pollination way and flower hormonization, eggplants formed the highest number of flowers with long pistil and much less - with medium and short pistil. It was shown that the tendency to formation the flowers with particular type of pistil is the variety trait of eggplants. The highest number of flowers with long pistil was observed in varieties 'Solara F1' and Epic F1, and those with medium pistil - in 'Black Beauty' variety. Heterostyly phenomenon occurring in eggplant' s flowers affected the plant's fruiting. The most fruits were set from flowers with long pistils than from those with 'um and short ones. Fruits formed from long pistil flowers were characterized with significantly greater mean weight and size, than those formed from medium and short pistil ones. No significant influence of pollination method on eggplant fruit quality was ,found in three years of study. Fruits achieved due to three pollination methods were characterized with similar mean weight and diameter. Fruits with significantly larger length were achieved from flowers pollinated by bumble-bees than from self pollinated ones.
