Resumo: Lepidaploa rufogrisea is a promising candidate in the search of natural herbicides, with compounds (sesquiterpene lactones-glaucolide B) which have been reported to present phytotoxic potential against weeds. Thus, this work aimed to accomplish the phytochemical investigation of L. rufogrisea as well as the evaluation of its biological effects on the plant model Lactuca sativa. To this end, different extracts (aqueous, hydroalcoholic and hexane) of L. rufogrisea at different concentrations [0.25, 0.5, 1.0, 2.0 and 4.0 % (m/v)] were evaluated from macroscopic (percentage of germinated seeds, germination speed index and root length) and microscopic analysis (mitotic index and cell cycle alterations) in plantlets (150 per treatment) and meristematic cells (10 000 per treatment) of L. sativa var. Cristina. The extracts decreased the germination speed index and also the root growth of L. sativa plantlets. Cell proliferation was not significantly affected by the extracts. However, some chromosome and nuclear alterations in the mitotic spindle were observed, due to the interference of allelochemicals present in L. rufogrisea. Moreover, the plant model L. sativa demonstrated to be efficient for this kind of studies.

Por lo tanto, este trabajo tuvo como objetivo lograr la investigación fitoquímica de L. rufogrisea, así como también la evaluación de sus efectos biológicos sobre el modelo de planta Lactuca sativa L. Para esto, diferentes extractos (acuosos, hidroalcohólicos y hexanos) de L. rufogrisea fueron evaluados. El porcentaje de semillas germinadas, el índice de velocidad de germinación y la longitud de raíz de plántulas de L. sativa var. Cristina fueron evaluadas, así como también la citotoxicidad de los extractos en las células meristemáticas. Los extractos disminuyeron el índice de velocidad de germinación y también el crecimiento de las raíces de las plántulas de L. sativa. La proliferación celular no se vio significativamente afectada por los extractos. Sin embargo, se observaron alteraciones cromosómicas y nucleares, debido a la interferencia de los aleloquímicos presentes en L. rufogrisea en el huso mitótico. Además, el modelo de planta L. sativa demostró ser eficiente para tales estudios.Universidad de Costa Rica2018-10-23T13:49:41Z2018-10-23T13:49:41Z2017-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfARAGÃO, F.
