Diversity and phytosociological analysis of weeds in a Musaceae crops from the ecuatorian tropics

One of the first steps for the development of new control tactics and integrated weed management, is to know the composition and diversity of the weed flora affecting the crop.

description One of the first steps for the development of new control tactics and integrated weed management, is to know the composition and diversity of the weed flora affecting the crop. Knowledge of the dominant weed species is the basis forplanning suitable control strategies and determine the management of the crop. This work analyzes the diversity of weeds and identifiesthose species predominant within the ecosystem of Quevedo (Ecuador). Results showed 55 weed species belonging to 22 families, with the Compositae, Poaceae and Euphorbiaceae families having the higher number of species in the monitored area. The ecosystem presented slightly high diversity, high dominance, and medium specific richness. The functional analysis revealed 43 dicotyledonous species and 12 monocotyledonous species. Among the dominant weed species, we found the “piñita” (Murdannia nudiflora (L.) Brenan) that presented medium agresiveness, followed by the “caminadora” (Rottboellia exaltata L. f.) with high agresiveness and “tridax” (Tridax procumbens L.) with slight to medium level of agresiveness.  No species had an importance value greater than 28.2 % in the monitored area.

Uno de los primeros procesos para el desarrollo de nuevas herramientasde control y manejo integrado de malezas, implica el conocimiento de lacomposición y diversidad de la flora que incide en la producción del cultivo. El conocimiento de las especies de malezas dominantes es la base de la planificación de estrategias de control idóneas, que determinan el manejo del cultivo. Este trabajo analiza la diversidad de malezas y determina la identificación de las especies predominantes dentro del ecosistema de la localidad de Quevedo (Ecuador). Los resultados señalan que en el área monitoreada se encontraron 55 especies, incluidas en 22 familias, destacándose las Compositae, Poaceae y Euphorbiaceae con el mayor número. El ecosistema presenta diversidad levemente alta, dominancia alta y riqueza específica media. El análisis funcional revela 43 especies dicotiledóneas y 12 monocotiledóneas. Entre las especies de malezas dominantes se encontraron a la “piñita” (Murdannia nudiflora (L.) Brenan) que presenta nocividad media, seguida de la “caminadora” (Rottboellia exaltata L.f.) con alta nocividad y “tridax” (Tridax procumbens L.) con nivel medio de nocividad. Ninguna especie tiene un valor de importancia superior al 28,2 % en el área monitoreada.  Facultad de Ciencias Agropecuarias 2018-12-27 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html https://revistas.unc.edu.ar/index.php/agris/article/view/22966 10.31047/1668.298x.v35.n2.22966 AgriScientia; Vol. 35 No. 2 (2018); 43-52 AgriScientia; Vol. 35 Núm. 2 (2018); 43-52 1668-298X 10.31047/1668.298x.v35.n2 spa https://revistas.unc.edu.ar/index.php/agris/article/view/22966/22676 https://revistas.unc.edu.ar/index.php/agris/article/view/22966/29297
