Wide ranges of studies were published in the last years in this subject area, presenting different aspects of the problem. This study tries to get answers to the problem of relation between the concentration of pigments and the growth rate under different light intensities, with a particular focus on chlorophyll and anthocyanins pigments. Also we are interested in seeing if the pigments concentration has an impact on the color of these two specific plants. Our findings are based on experimental work, basic techniques of mathematical modelling and knowledge from different materials that we have been reading through the semester. These findings provide information about the pigments as well as about the growth of two different plants, Myriophyllum aquaticum and Myriophyllum tuberculatum. These two plants were grown under different light intensities and were monitored regularly in a period of 27 days. From the first part of the experiment we could see that Myriophyllum tuberculatum is growing faster than Myriophylum aquaticum in that period. But their growth rates are related to different light intensities in a different way. The second part of the study was to find the implication of chlorophyll concentration and anthocyanins concentration, on the growth of the plants. The chlorophyll concentration in Myriophyllum aquaticum was clearly higher than the chlorophyll concentration in Myriophyllum tuberculatum. The results are showing that the chlorophyll concentration, which dominates the growth of the plants, is decreasing with the increase of the light intensity. But the speed of the decreasing is relevant to the protective function of anthocyanins. This paper didn’t get an accurate result as a quantitative conclusion, but we hope that this paper will be helpful for students and academic staff on relative investigationWide ranges of studies were published in the last years in this subject area, presenting different aspects of the problem.
