Abstract: Effects of culture temperature , storage temperature , GA treatment and illumination intensity on spore germination of Sphenomeris chinensis were studied using randomized blocks experiments and analysis of variance . Compared with room temperature (20 - 25℃) , the germination velocity was higher at the culture temperature of 28℃, although their maximal germination percentage was the same . Storage temperature (A) significantly ( P < 0 .01) affected spore germination , and germination of spores was reduced when stored at - 20℃. GA (B) did not affect germination. Illumination intensity (C) significantly ( P < 0 . 01) affected germination. There were no significant difference between full and weak illumination , but the dark reduced germination percentage . A×B, A×C, B×C and A×B×C had no significant interaction effect .
