Bulblets isolated from small globule-scale of Fritillaria camtschatcensis Ker-Gawl. were cultured on MS medium containing plant hormones under light of 1,500 lx at 25 degree C for 8 weeks. NAA, kinetin and 24-epibrassinolide (EB) were tested for their effects on growth, leaf emergence, and rooting of bulblets. With individual plant hormones, EB at 0.01 ppm enhanced bulblet growth and rooting, whereas o.1 ppm kinetin was optimum for advancing leaf emergence. With respect to combinations of plant hormones, that consisting of 1.0 ppm NAA and 0.1 ppm kinetin was optimum for bulblet growth and leaf emergence, whereas 1.0 ppm NAA, 0.1 ppm kinetin and 0.01 ppm EB promoted rooting of bulblets
