Abstract

Abstract: The major technology which affecting rapid asexual propagation and commercial production of
Phalaenopsiswas discussed. Results showed that the type of culture medium and the time of subculture directly
affected the p ropagation rate of its p rotocorm. The propagation rates of protocorm in the modified Kyoto and KC
media were significantly higher than that in MS medium. The op timal subculture time was 2.5 months. The
maturity of seedlingswas accelerated by using two step s cultivation, and it only needed seven or eightmonths
in tube. According to investigation on the abloom p lant of p rotocorm of five varieties p ropagated for 20 genera
tions, the results showed that the colony characters of these blooming plants are stable and the rate of variation
of two protocormswas lower than 1 /10 000 in the propagation of 18^th - 20^th generations.

Key words: Phalaenopsis, Tissue culture, Commercial p roduction
