Abstract:
The present study provides quantitative assessment of the vegetative yield, growth characteristics, metabolic products, elemental composition and antimicrobial bioactivity of five common macrohydrophytes: Bolboschoenus glaucus (Cyperaceae), Veronica anagallis-aquatica (Scrophulariaceae), Nymphaea lotus (Nymphaceae), Pistia stratiotes (Araceae) and Myriophyllum spicatum (Haloragidaceae). These plants tend to flourish vegetatively during the summer season (June-August). Their relative growth rate, relative assimilating surface growth rate and net assimilation rate were higher during early vegetative stage (February-May). The highest percentages of protein and lipids content were recorded in Nymphaea, while the crude fiber content was higher in Bolboschoenus than in other species. The macronutrient elements were detected with relatively high concentration and sodium cation appeared to be an essential accumulatent as compared with K, Ca and Mg. Myriophyllum appeared to be the major accumulator species of heavy metals, while Pistia appeared to be the minor one. Sterols, alkaloids, flavonoids, tannins, saponins and resins were detected in these plants. Nymphyaea was found to have the most effective antimicrobial activities than the other studied species.
