Abstract
This report details the findings of an investigation surrounding the growth and death rate of Lemonodaie. Though it holds a staple point as a major pest in aquatic areas, it has been largely ignored due to the difficulty regarding controlling the population of such a plant. This was the main stimulation in executing this study, as finding an effective method of controlling duckweed population would be an interesting breakthrough in aquatic regulation. Due to duckweed growing at an unprecedented rate, treating this condition was a relatively strong dose of zinc chloride (ZnCl2), of which were added to separate aquariums of duckweed at different levels, to measure the retardation of the growth of the duckweed. It is reasonable to predict that if the specimen is exposed to over 18mg/l of zinc, then the duckweed will be terminated at a far higher rate than those of lesser dosage, though only if kept in a consistent environment, in comparison to the 15mg/l, of which it shall incorporate a resistance.
As a result, the hypothesis concluded to be un proven, with both 18 and 15 gram zinc levels dying within a short timeframe, without building any noticeable resistance.
