Abstract

Abstract: The factors of influencing spore germination was studied in this paper. The suitable culture medium and spore density for Osmunda japonica Thund. spores was 1/ 8 MS and 3 000/ cm². After germinating, spores grew into the filiform shape , flaky , prothallium and developed into sporophyte 4 months later. The optimized culture medium for prothallium to disintegrate sporophyte was 1/ 8 MS + 6-BA 1 + NAA 0. 5 and culture mediumof root growing was 1/ 8 MS + 6-BA 0. 5 + NAA 1. 0. The growth of seedlings was closely related to sunlight , temperature and humidity.

Key words: Osmunda japonica Thund., Rapid propagation
