Abstract: Phalaenopsis aphrodite Rchb. F. is a plant of great ornamental and economic value, and its growth has strict requirements in terms of environment. In order to establish the rapid propagation of Phalaenopsis aphrodite Rchb. F., this study used the popular large-flowered variety ‘RED SUN’, which is found on the market, as the material, and studied the effects of pedicel taking time, site, plant growth regulators, and organic substances on the establishment of a regeneration system. The results indicated that the best combination of initiation culture was collecting peduncles in January + upper position of peduncles + 0.1% HgCl 2 sterilization for 8 min. The best recipe for inducing adventitious buds was MS + TDZ 0.4 mg/L + NAA 0.5 mg/L. The optimal combination for adventitious bud propagation was MS + TDZ 0.2 mg/L + NAA 0.4 mg/L. The best recipe for strong seedling from aseptic seedlings was MS + NAA 0.4 mg/L + banana powder 20 g/L + tryptone 2 g. The best recipe for rooting for aseptic seedlings was 1/2 MS + IBA 0.5 mg/L + charcoal 2 g/L. The best combination of acclimation and transplanting for Phalaenopsis was using sphagnum in the training seedling room, which produced a seedling survival rate of 97%. Our findings, therefore, demonstrate the methods of rapid breeding of the Phalaenopsis orchid, which provide a scientific basis for the conservation of this species.
