Abstract: A culture vase comprises generally a transparent cylindrical body having an introversively spherical portion on the top and a less diameter opening on the bottom, a culture seat disposed into the opening and a cover having threads thereon coupled to a neck of the opening. Furthermore, both of the culture seat and the cover have at least an air inlet thereon in cooperation with a circular filter disposed thereinbetween, thereby, permitting the entrance of the fresh air and preventing the germs or bacteria from entering into the cultured explant.
