Abstract

ALDAVE, Telassim  and  APONTE, Héctor. Comparative study of the percentage of carbon among species of vascular flora of the Pantanos de Villa (Lima-Peru). Arnaldoa [online]. 2019, vol.26, n.2, pp.751-760. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.262.26216.

Although 50% is frequently used as a measure of the percentage of carbon (%C) in plants, this value varies between the different life forms of plant species and even between the organs of the same species. Adjusting these percentages is extremely important since the change in units can lead to considerable variations in the calculation of carbon stocks. The objective was to analyze the %C among 15 species of vascular flora, verifying the variability. The study area was the Pantanos de Villa Wildlife Refuge (Lima, Peru). Complete samples (stem, root and leaves, as applicable) were collected per species and analyzed following the Walkley and Black method. The %C was compared by separating the plants into three groups: a) succulents, b) free floating aquatic plants and c) amphibian plants. Differences (p < 0.05) were found among the %C of the groups of succulent (33.77% ± 7.05), free floating aquatic plants (39.25% ± 11.76) and amphibian plants (48.97% ± 9.32). The variability among %C of the most abundant vascular flora species of the Pantanos de Villa was evidenced; finding that succulent and free floating aquatic plants have lower values than amphibian plants.
