TRINDADE MARIA HELENA REZENDE JOSÉ R. PAULA LETÍCIA A. GONÇALVES Multidisciplinaria (Ciencias Naturales y Exactas) ontogeny Volatile oil histochemistry secretory structure Trichogonia cinerea is endemic to Brazil and occurs in areas of cerrado and campo rupestre. In this study, we characterized the glandular and non-glandular trichomes on the aerial parts of this species, determined the principal events in the development of the former, and identified the main constituents of the volatile oil produced in its aerial organs. Fully expanded leaves, internodes, florets, involucral bracts, and stem apices were used for the characterization of trichomes. Leaves, internodes, florets, and involucral bracts were examined by light microscopy and scanning electron microscopy, whereas stem apices were examined only by light microscopy. Branches in the reproductive phase were used for the extraction and determination of the composition of the volatile oil. The species has three types of glandular trichomes, biseriate vesicular, biseriate pedunculate, and multicellular uniseriate, which secrete volatile oils and phenolic compounds. The major components identi fi ed in the volatile oil were 3,5-muuroladiene (39.56%) and butylated hydroxytoluene (13.07%). 2016 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32744812026 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.88 |
