Abstract:Summary

The effects of CO2 concentration (350 and 1200 μmol mol-1), growing media (peat + perlite, 3:1, peat + coco dust, 1:1; and coco dust alone), and concentration of nutrient solution (EC 2.1 and 2.8 mS cm-1) on growth of gerbera microcuttings, leaf nutrient content, and the chemical properties of the growing media were investigated. Plants grown in peat + coco dust had the highest dry weights of leaves and roots. There were no significant differences in the fresh and dry weights of leaves and roots due to concentration of nutrient solution. CO2 enrichment increased all growth variables, except leaf number. Leaf nutrient content of gerbera cuttings and chemical properties of growing media after eight weeks of growth, with reference to all treatments, are discussed and presented as tables.
