EFFECTS OF TOTAL NITROGEN AND BA ON IN VITRO CULTURE OF PHALAENOPSIS

K. Kanchanapoom, T. Anuphan , S. Pansiri
The effects of total nitrogen and 6-benzyladenine (BA) on growth of Phalaenopsis orchid were studied. Phalaenopsis seedlings were cultured on Vacin and Went (VW) medium containing 4.5, 6, 7.5 or 9 mM total nitrogen in combination with 0, 5, 10, 15 or 20 mg L-1 BA for 5 months. The results revealed that VW medium supplemented with 9 mM nitrogen and 10 mg L-1 BA gave the best leaf length, 3.4 cm, and width, 1.3 cm, with an average of three leaves per plantlet. However, the greatest number of roots (six roots per plantlet) and root length (3.9 cm), were found on the VW medium containing 6 mM nitrogen and 5 mg L-1 BA. All rooted plants were successfully acclimatized and potted in the greenhouse.
