The study was to seek effects of citric acid on Phalaenopsis I-Hsin Cream ‘KHM246'plantlet growth and componenets of the gaseous environment in vitro. Plantlet had different growth rate at 70 days after subculture. The finest performance for root length and root diameter which gave 17.8％ and 5.5％ increment, and fresh weight and dry weight of root which gave 27.8％ and 37.9％ increment were found in citric acid 60 mg/l supplement in medium. The plantlet has malic acid accumulation in the dark period. Adding different citric acid concentration in medium, carbon dioxide content in flask decreased depending on citric acid concentration increase and growing days. Ethylene content was higher in initial stage of subculture and decreased slowly along with increase of growing days.
