RESEARCH ON PROCEDURE THE MICROPROPAGATION FOR WHITE TRUMPET (Sarracenia leucophylla)

Abstract

White trumpet (Sarracenia leucophylla) is the most beautiful carnivorous tree in the genus Sarraceniaand. This a popular ornamental tree in the Vietnamese market. In order to improve the quality of in vitro seedlings and in vitroplant outside the nursery, environmental factors and culture conditions on the growth of White trumpet was investigated. Material samples usingfor experiments wasin vitro shoot, healthy, 1-1.5cm tall. The study showed that MS medium supplemented with 0.2 mg/L NAA, 1.0 mg/L BA, 30 g/L sucrose, 8 g/L agar gave the highest percentage of shots at 14.22 shoots/sample. The WV5 medium supplemented with 30 g/L sucrose, 8 g/L agar, illuminated at 3000 lux, the shoots reached a height of 6.43 cm, erect, leafy, green, open, fresh weight reached 0.89 g/shoot. Using WV5 medium supplemented with 1.0 mg/L IBA induced early rooting after 30 days of culture, high rooting rate of 95.56% shoots, number of roots reaching 13.44 roots/plant. Plants after 1 month when planted outside the nursery grow healthy, the survival rate is over 95%.
