Abstract: Hylocereus undatus was introduced from Taiwan in 1999 and its cultural practice was studied in Xiamen. The results showed that the stem (length 15-20cm, width 4-5cm) rooted after 17-20d of cuttage, the rooting percentage was up to 100% and one year later the length and width reached 213cm and 7-8cm, respectively; the survival ratio of grafted seedling was 70%-90% and sprout grafting had a higher survival ratio; bud bursted after 4d of seed sowing, the germination percentage was 50.9% and one year later the length and width reached 25cm and 3cm, respectively; grafted seedling and cut seedling flowered in the next year and the cut seedling had self fertility. The individual weight of fruit was 673g and the fruit tasted fine.
