The experiments were conducted to develop the technology for increasing seed viability by priming treatments, plant growth regulators and low temperature stratification in medicinal plants. Ledebouriella seseloides, Glehnia littoralis, Angelica dahurica and Agnelica gigas were used in these experiments. The percentage of germination had higher 20-25 degrees centigrade than 30 degrees centigrade incubation in tested crops. Osmotic conditioning priming by polyethylene glycol(-5 - -14bars) increased the germination rate in Angelica dahurica and reduced the number of days to 50% germination from final germination in four tested crops. The percentage of germination also increased by 0.1-0.5% and 0.3% KNO3 treatment in Ledebouriella seseloides and in Angelica dahurica, respectively. Stratification treatments during 30-50 days have higher germination and faster days to 50% germination from the final germination. GA3 treatment increased its germination rate as the level increased from 1 ppm to 500 ppm as compared to control.
