Effects of different dilutions of municipal waste water on some physiological aspects of Eichornia crassipes Solms

In the present study effects of different dilutions of municipal waste water were investigated on the physiological aspects of Eichornia crassipes Solms. There were five different concentrations of municipal waste water (0%, 25%, 50%, 75% and 100%) which were labeled as T0, T1, T2, T3 and T4 respectively. Vegetative growth effected by the waste water was monitored at the end of the experiment. Vegetative reproduction of the plants was also studied by observing number of baby plants per plant. Rate of photosynthesis and rate of transpiration of the plants growing in different concentrations of municipal waste water were studied as physiological parameters. Before start of experiment and after harvesting the plants waste water samples were also analyzed. T4 showed highest rate of physiological parameters among all the treatments while T0 had the lowest rate of physiological parameters among all the treatments. These physiological activities were responsible for higher root shoot length in T4.
