| Growth of Campanula punctata 'Rubriflora' plantlets, as affected by three levels of photosynthetic photon flux (PPF), 70, 110, and $220{mu}mol{cdot}m^{-2}{cdot}s^{-1}$, two levels of $CO_2$ concentration, 500 and $1,500{mu}mol{cdot}m^{-1}$, and two levels of number of air exchanges per hour (NAEH), 0.1 and $2.8 h^{-l}$, was studied. Explants were obtained from photomixotrophically-micropropagated plantlets. Four explants were planted in each $3.7{ imes}10^{-4}m^3$ polycarbonate box containing MS basal medium and no added sucrose. Explants were cultured under cool-white fluorescent lamps for $16h{cdot}d^{-1},;at;25pm1^{circ}C$ temperature, and $70~80%$ relative humidity In treatments of $2.8h^{-1}$ NAEH, a 10mm round hole made on the vessel cap was sealed with a microporous filter. For higher $CO_2$ concentrations in the culture room, $CO_2$ gas was provided from a tank of liquefied $CO_2$. Fresh and dry weights, length of the longest root, and number of leaves significantly increased with increasing PPF and especially $CO_2$ concentration. Length of the longest root, number of leaves, fresh and dry weights, and chlorophyll concentration were enhanced with increased NAEH. However, leaf area was the smallest in the $220{mu}mol{cdot}m^{-2}{cdot}s^{-1};PPF;2.8h^{-1}$ NAEH and especially, $1,500{mu}mol{cdot}mol^{-1};CO_2$ concentration treatment. Treatment effect became more produced with time. Overall, treatment with $220{mu}mol{cdot}m^{-2}{cdot}s^{-1};PPF;and;1,500{mu}mol{cdot}mol^{-1};CO_2$ gave the most vigorous growth. |
