Abstract
[ Objective ] To study the effects storage condition on seed vigor of three medicinal plants. [ Method ] With the seeds of Atractylodes macrocephala Koidz. , Scutellaria baicalensia Georgi. Seed and Polygala tenuifolia Willd. As the plant materials, seeds with moisture contents of 3%, 5% and 15% were stored at - 10 ℃ ,0 ℃ ,20 ℃ and 36 ℃ for one year. Change laws of germination rate and vigor index of three medicinal plant seeds stored after one year were preliminarily researched. [ Result] Among the two controlling factors, water corltent had more significant impact on seed germination rate and vigor index than temperature. Germination rate and vigor index of three medicinal plant seeds reduced as the decrease of storage temperature and seed water content. When the water content was controlled within 3% -5%, temperature had no significant impact on the seed germination rate and vigor index. However, seeds with 15% water content at 0 ℃ showed relatively low germination rate and vigor index. [ Conclusion ] Both seed germination rate and vigor index were affected by water content and storage tempera-ture.关键词
