The factors which affected root system growth of Phalaenopsis clone seedlings were studied. The experiment results showed: the affecting factors were the basic medium composition of rooting culture, the supplements, the plant growth regulators, the culture time and the light intensity. The best effect of the root system growth was obtained by the use of modified Hyponex basic medium supplemented with peptone 1 mg/L, 10 % coconut juice and IBA 1 mg/L, and culturing for 3 months under the light intensity of 1000-2000 lux in early days, then increased to 4000-8000 lx later period. the rooting rate was 100 %, the average root length was 3.3 cm, the rate of multiple root was 84 %.
