Leaf anatomy of Ficus maroma (Moraceae), and analyse of exposed leaves to environmental pollution in the province of Tucumán (Argentina)
Cabrera, Cecilia N.; Graciela A. Gelsi; Patricia L. Albornoz; Marta E. Arias, 2009. “Leaf anatomy of Ficus maroma (Moraceae), and analyse of exposed leaves to environmental pollution in the province of Tucumán (Argentina)”. Lilloa 46 (1-2). This paper describes the leaf anatomy of F. maroma and analyses the changes in exposed leaves to environmental pollution. Fresh material was fixed in FAA. Conventional histological techniques were used. The leaf is dorsiventral and hypostomatic. Adaxial epidermis is pluriestratified and the abaxial is uniestratified. Trichomes are single and glandular. Stomata are actinocytic and cyclocytic type. Cystolits, druses and cubics crystals are present. Petiole subcircular exhibit tree bicollateral vascular bundles. According to statistics analysis, exposed leaves to atmospheric pollution show changes anatomycal. It characterizes the leaf anatomy of F. maroma and could be considered this species as bioindicator of environmental pollution.

Arias, 2009. “Anatomía foliar de Ficus maroma (Moraceae) y análisis de hojas expuestas a la polución atmosférica en la provincia de Tucumán (Argentina)”. Lilloa 46 (1-2). El objetivo del trabajo fue estudiar la anatomía foliar y analizar los caracteres histológicos en hojas expuestas y no expuestas a la polución atmosférica. Las muestras fueron colectadas de ejemplares del Jardín Botánico de Fundación Miguel Lillo, Tucumán. Para el estudio anatómico se emplearon técnicas histológicas convencionales en hojas frescas y fijadas en FAA. La epidermis adaxial es pluriestratificada y la abaxial uniestratificada; los tricomas son glandulares con pie bicelular y cabeza pluricelular. Lámina dorsiventral, hipostomática, estomas tipo actinocíticos y ciclocíticos. Presencia de cistolitos, drusas y cristales cúbicos. Pecíolo subcircular con tricomas simples, colénquima subepidérmico y tres haces vasculares bicolaterales en porción media. Según el análisis estadístico los caracteres que mostraron cambios significativos fueron: aumento del grosor de la cutícula en epidermis adaxial, espesor del tejido en empalizada y mayor densidad estomática, en hojas expuestas a la polución. Se caracteriza la anatomía foliar de F. maroma y podría considerarse a esta especie como bioindicadora de la polución atmosférica Fundación Miguel Lillo 2009-12-07 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://www.lillo.org.ar/journals/index.php/lilloa/article/view/447 Lilloa; Lilloa 46 (1-2) (2009); 34-42 Lilloa; Lilloa 46 (1-2) (2009); 34-42 2346-9641 spa http://www.lillo.org.ar/journals/index.php/lilloa/article/view/447/456 |
