The effects of CO2 enrichment on growth rate and flowering were investigated in Sonerila picta, a Melastomataceae species. The plant height, leaf number, branch spread and root growth increased under 1200 and 2100 ppm CO2 compared with those in ambient CO2 (340-450 ppm). Flowering was advanced by 7 d and number of florets per plant increased by 70% under 1200 and 2100 ppm CO2. The increase in florets under CO2 enrichment may be related to increased number of mature branches and increased flowering percentage of the flower buds that differentiated on the branches. The CO2 enrichment is useful to improve the growth rate and flower quality of S. picta.
