Abstract

Light intensity has a profound effect on the growth of Azolla pinnata R. Brown. Fresh weight, dry weight and moisture content were maximum at 80 000 lux, but maximum frond area was attained in 50% light intensity. There was a wide variation in frond colour under different treatments. Frond texture, root characteristics and sporocarp production were also affected. The plant expresses heliophytic characteristics.
