들꽃(Rhodiola elongata Fisch. et Mey) 種子의 發芽에 미치는 生長調節物質의 效果

Effects of Growth Regulators on the Germination of Rhodiola elongata Fisch. et Mey

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.
