Abstract: The spore sterile culture and routine propagation of Pteris cretica ‘Albo-lineata’were studied respectively. The results showed that the spore germination was of the Vittaria2type while the gametophyte development was of the Ceratop teris2type. The maximum germination rate was obtained in 1 /2MS medium, which reached 82.3%; the medium with sucrose concentration being less than 2% was appropriate for spore germination; the highest rate of gametophyte to sporophyte was achieved in MS medium, which reached
53.4%; the transplant survival rate of sporophyte in vitro reached above 80%. The mixed soil ( the turf and the sand blend in the volume ratio of 1 to 1) was the optimal growing medium for spore routine propagation, in which the rate of gametophyte to the sporophyte was up to 89.2%. When the first cotyledon of the sporophyte seedling grew to 1 - 2 cm, the sporophyte seedlings should be rep lanted in the growing medium which was composed of turf, vermiculite, sand and organic fertilizers. The highest survival rate reached 98.1%. The
young gametophyte seedlings of 10 cm height had already possessed ornamental values.
