The experiment was carried out in three unheated plastic tunnels from 1998-2000.
The aim of the study was to compare the effects of two methods of
flower pollination (self-pollination and using bumble-bee) as well
as flower hormonization on the yielding of three cultivars of
eggplant - ‘Black Beauty’, ‘Solara F1’, and
‘Epic F1’. The
profitable effect of pollination by bumble-bee (Bombus
terrestris) and flower hormonization (β-naphthoxyacetic
acid) on the yield of eggplant under cover was found.
A significantly higher marketable yield of fruits and early yield of
fruits were achieved from plants whose flowers were pollinated by
insects and hormonized in comparison with those self-pollinated.
Pollination of eggplant by bumble-bee brought about a significant
increase in number of formed fruits of marketable yield as
compared with plants whose fruits were set owing to flower
hormonization and self-pollinated. The analysis of yield results
showed that the introduction of the bumble-bee and growth
regulator into eggplant cultivation positively affected the
biometric traits of eggplant fruits. The positive effect of these
two operations resulted from significant improvement of fruit
quality which were greater in weight and size. The evaluated
cultivars, regardless of the method of pollination and flower
hormonization, differed significantly with regard to yielding. The
highest marketable yield and early yield of fruits were found from
cultivars: ‘Epic F1’ and
‘Solara F1’, followed by
