These experiments were conducted to investigate the growth and characteristics of Adenophora triphylla DC. seed, and effects of some pretreatments and light condition on the gemination of it. The results were as follows. Seed coat was soft and white at 30 days after flowering, but it became hard and brown from 40 days. The 1,000 grain weight was 247mg at 40 days after flowering and high at 50 days as 268mg, and decreased from 60 days. Germination percentage was highest at 100ppm $GA_3$ treatment for 24 hours as 96.7% and 88.3% at moistured treatment at $0^{\circ}C$ for 7 days, but only 40% at control. Adenophora triphylla. seed was light germinator, but it could be germinated 80% even under dark condition if $GA_3$ was treated 100ppm for 24 hours. The optimum temperature of germination in Adenophora triphylla. seeds was $25^{\circ}C$.
