| This study was conducted to investigate the effects of $CO_2$ concentration(310 or 950$mu$ mol.mol$^{-1}$ ) and air current speed(0.3, 0.5, 0.7 or 0.9m.s$^{-1}$ ) on the growth and development of eggp1ant Plug seedlings (Solanum melongena L.) under artificial 1ighting. For the treatment of $CO_2$ enrichment, stem length and diameter, the ratio of stem length to stem diameter, plant height, leaf area, net photosynthetic rate, top dried weight were significantly different at 1% level. Stem length of plug seedlings decreased at the condition under enriched $CO_2$ and high air current speed above plug stand. Stem diameter of plug seedlings increased and plant height decreased with the increasing $CO_2$ concentration. Plug seedlings had maximum net photosynthetic rate at the air current speed of 0.7m.s$^{-1}$ . Net photosynthetic rate at $CO_2$ concentration of 950$mu$mol.mol$^{-1}$ increased by 46% than those at 310$mu$mol.mol$^{-1}$ . Thus $CO_2$ enrichment would be effective for the production of plug seedlings with high quality. |
