Application of Gas Permeable Film for Cultivation of Aquatic Plants

Completely closed bags made with a gas permeable film are available for culture of two aquatic plants, Eleocharis vivipara and Sphagnum nemoreum. E. vivipara, the C3-C4 photosynthesis interconvertible plant, was successfully grown in a sugar free liquid medium and developed C3 type culms even under relatively high intensity of illumination. Growth of S. nemoreum was clearly stimulated in the bag using a sugar containing medium. The film system is promising for further study of responses to environmental factors such as intensity and wavelength of illumination.
