In this paper, the culture conditions of water hyacinth (Eichhornia crassipes Solm) in vitro were studied. When stem explants of water hyacinths were cultured on MS medium containing 6 BA 3 mg/L and with lighting provided by cool white fluorescent lights (2 000 lx, 12 hours/day,25 ℃) for 3～4 weeks, many adventitious shoots were induced from the explants, with shoot induction frequency reaching 46 7%. But, only calli were induced to form from the leaf and root explants in the same conditions. The experimental results showed that the plants of ...
