Preliminary study on maturation and spore release of Gloiopeltis furcata and G.tenax in indoor cultivation

The influence of temperature, light and nutrient solution on the mature and spore release for Gloiopeltis furcata and G.tenax was investigated in the laboratory. G.furcata could mature and release spores at 10~20℃ while G.tenax could mature and release spores at 12~24℃. This two species of Gloiopeltis could mature and release spores at illuminance 2 500~8 500 lx. For no nutrient addition to the stocking water the two species of Gloiopeltis could mature and release spores, while nutrient addition too high (80 mg·L^-1 NaNO₃ and 8 mg·L^-1 KH₂PO₄) it was not good for the mature and spores release of this two species alga.
