| Abstract:
The influence of the nutrient solution concentrations (EC 1.4, 4.2, 7.0 mS/MDcm-1) on the growth and nutrient element content of Homalomena 'Emerald Gem' at two CO2 concentrations (350 and 1200 μmol/MDmol-1) was investigated after transfer out of culture. Increasing electrical conductivity of the nutrient solution decreased survival, reduced growth of shoots and roots and increased nutrient element content of shoots irrespectively of the CO2 concentration. CO2 enrichment improved survival of plantlets grown at higher EC, promoted ex vitro growth of Homalomena microcuttings and increased accumulation of mineral elements in plantlets. | |
