Sažetak
The effect of two hydroponic substrates (organic mix with perlite and rockwool) on the flower production of three gerbera cultivars ('Bordorex', 'Dalma' and 'Goldy') was studied from August 2005 through March 2007. Flower production was higher in organic substrate compared to rockwool in Dec. 2005 (34%), Apr. 2006 (12%) and Mar. 2007 (20%). Interaction between type of substrate and cultivars for flower production was found in Jan., Sep. and Nov. 2006.. Production of flowers of ‘Goldy’ in organic substrate was higher compared to other combinations, except in Jan. 2006. when the production was the same as of ‘Bordorex’ on organic substrate. Through experimental period cultivars had more influence on production of flowers than substrate. Diameter of flower stalk and diameter of inflorescence were influenced by cultivar as well. Under the conditions of our study there was not much influence of substrate type on flower production or on flower stem quality, however choice of cultivar had a significant effect.
