The effects of temperature, prechilling, chemicals such as GA₃, IAA, kinetin and KNO₃ on the germinability of Foeniculum vulgare seed of medicinal plant were examined.
In Foeniculum vulgaret the germination rate appeared to be around 50~60% or more in general, showing no differences in germination rate with different temperatures, promoting substances, physical or chemical treatments, and prechilling treatments.
The observation of embryo under stereoscopic microscope for Foeniculum vulgare in Umbelliferae showed that seeds with or without embryo was almost the same in number. This result suggests that the lower rate of germination in this species is caused by embryolessness of seeds. The straight-shaped embryos as well as Y-shaped embryos were also observed. Foeniculum vulgare of medicinal plants in Umbelliferae were observed under scanning electron microscope, and did not show any opening problem near micropyle area.
Final count should be made on 7th day of germination test.
