This study was attempted to establish the propagation and cultivation methods of Rhodiola elongata Fisch. et Mey. as a part of development of northern plant resources. Seeds were treated and investingated at the 15, 20, 25∘C and 100, 200, 400, 800ppm of the growth regulator GA3, BA, and Kinetin. The results obtained are summarized as follows: Seeds of R. elongata were the most vigorously germinated at 15-20∘C, and rate of germination at 25∘C decreased gradually. Germination rate of seeds that treated growth regulators was remarkably increased than non-treated ones, and GA3 treatment among the growth regulators showed the best effects. The effective concentration of GA3 for germination of R. elongata seeds was 400 ppm.
