Abstract
CO2 enrichment in greenhouse is a suitable way which reduces production time, better growth vigor and also higher plant quality. The main aim of this study was to find out the effects of artificial CO2 enrichment under different light levels on rooting of the ornamental foliage Codiaeum variegatum. The experiment was planned as a split plot based on a completely randomized design. CO2 was considered as the main plots (380 as control, 750 and 1050 ppm) and these light intensities as the sub plots (10000 as control, 12000 and 14000 Lux) were used. Results showed a significant increase on measured traits with elevating levels of CO2 and light. Highest measured values of different traits were observed at 12000 Lux light intensity and 750 ppm CO2 enrichment. Light intensity × CO2 interaction had a significant effect on leaf length, leaf number, root quality, root volume, root length (P≤0.01) and rooting percentage at (P≤0.05). Spad chlorophyll unit was not noticeably significant. Rooting and plant growth generally raised along with both light intensity and CO2 elevation.
