ABSTRACT
The experiment was carried out in the years 2001-2002. Young plants of the wax begonia 'Eureka Bronze Rose' were grown in the greenhouse in pots using a peat substrate mixed with sand. B-Nine, Cycocel and Topflor were applied once or twice at 14-day intervals, through leaves and the soil. In May the plants were bedded and every month their height was measured and the number of buds and flowers counted. The dynamics of growth and flowering of the bedded plants was observed. The strongest and longest-lasting growth retardant was Topflor, both foliar- and soil-applied. Soil-applied B-Nine and Cycocel were found to have no adverse effect on the number of buds and flowers.
Key words: Begonia semperflorens Link et Otto, retardants, growth, flowering.
