| Phytoremediation is an efficient technical alternative in remediation of sites contaminated with metals & metalloids. The objective of this study is to analyze the germination of two different Grasses (Buchloe dactyloides & Cynodon dactylon) in a contaminated site. These species are native of semi-arid regions, which make them drought resistant and tolerant to low temperatures. These kinds of grass don’t need so much water, so it is a very good alternative in arid climates. The experiment consisted in the observation of the two different species germinating in six kinds of soil with high content of As, Cd, Pb and Zn and pH between 5 and 9. Four repetitions were considered by type of seed and soil (treatment). Results were analyzed using a generalized lineal statistic model with desbalanced mating. Statistical differences were obtained between the treatments and the type of seeds. The results were compared using Tukey test (5%) and the coefficient of variation from grasses were compared, Buchloe dactyloides was 22, 9% and the Cynodon dactylon was 41,4%, Conclusion was that grass Buchloe dactyloides had the best germination in the analyzed soils. | |
