Abstract: Abstract:Browning is a common phenomenon of Phalaenopsis in vitro culture, this test attempts to explore the rapid propagation effective way of butterfly orchid stems Axillary process of in vitro to control their browning, bud induction. Tests prove that all those with axillary pedicel browning segment are lighter than axillary and Cytokinin KT browning symptoms lighter than BA, Bud induction rate than BA; It may reduce the browning that add the appropriate dose of PVP, activated carbon, citric acid etc, citric acid and PVP significantly make better than activated carbon, which provides a reference for the factory about the production of Characteristics flowers and plants.
