Abstract
Present experiments are conducted to study the seed viability and optimum germination temperature of Polygonatum odoratum var. pluriflorum that is known to have low germination ability and long germination duration. To enhance germination rate, various growth regulators and inorganic salts were employed. Low germination rate was obtained with 4 year old seeds, but not with $1{\sim}2$ year old seeds. The seeds germinated very well under $22{\sim}25^{\circ}C$ and germinated speed was rapid. Especially, $1{\sim}2$ year old seeds germinated at $25^{\circ}C$ showed $70{\sim}71.2%$ germination rate. Priming treatments using $GA_3$, IAA, NAA, kinetin, $KNO_3$, $KH_2PO_4$, $Ca(NO_3)_2$ were effective compared to control except BA. 1 year old seeds treated with $GA_3$ 0.5 mM and IAA 1 mM showed 96% and 93% germination rate, respectively.
