Il complesso delle Latomie a Siracusa: un bene culturale e ambientale da rivalutare.
2012
The authors present the results of a botanical study dealing with the gardens of the Latomie, a complex of spectacular quarries in Syracuse (Sicily) used in ancient times to get stones for building the Greek town, and today totally enclosed by the urban expansion. The present conditions of each garden are analysed as regards the primary arrangement and their exotic and wild flora in order to emphasize both the historical and cultural value, as well as the ecological and natural role of these particular archaeological sites. The presence of significant patches of natural vegetation, together with the development of dangerous invasive plants, suggest urgent actions for the management and valo…
Lo real y lo imaginario : el proyecto HUM2004-04939 sobre flora en el mundo ibérico
2008
“De lo real a lo imaginario. Aproximación a la flora ibérica durante la Edad del Hierro” es el título del proyecto Hum2004-04939 financiado por el Ministerio de Educación y Ciencia. El objetivo es hacer un estudio multidisciplinar de la flora con el fin de aproximarnos al uso y simbolismo de las plantas por parte de los Iberos. El método ha consistido en la combinación de datos paleobotánicos tomados de la antracología,la palinología y la paleocarpología, junto con los iconográficos. Se ha realizado un banco de datos con todos los restos arqueobotánicos y representaciones iconográficas de vegetales documentados en los yacimientos Ibéricos. En ambos casos se aplican criterios de identificaci…

De lo real a lo imaginario. Aproximación a la flora ibérica durante la Edad del Hierro
2007
"De lo real a lo imaginario" es el título de un proyecto cuyo objetivo es hacer un estudio de la flora de los iberos desde distintos puntos de vista con el fin de aproximarnos al uso y simbolismo de las plantas por parte de las sociedades antiguas. Para ello se va a combinar una visión estrictamente paleobotánica, basada en estudios palinológicos, antracológicos y paleocarpológicos, con la iconográfica, recogiendo todas las representaciones de plantas que aparecen en cerámica, escultura en piedra, objetos metálicos y monedas. Todos los datos se catalogan teniendo en cuenta su contexto y cronología. Con ello se pretende elaborar un catálogo de plantas conocidas y utilizadas, en diferentes conte…
Insular endemism in the Mediterranean vascular flora: the case of the Aeolian Islands (Sicily, Italy)
2012
The present paper briefly provides the state of the art of the knowledge on vascular plant endemism in the oceanic (“thalassogenous”) Aeolian Archipelago (Sicily). Preliminary analysis of distribution areas and review of recent literature on biosystematics of endemic species revealed that: (a) Aeolian strictly endemic taxa are just 6, i.e. about the 0.7 % of the local vascular flora; among them, just 4 can be considered (with doubt) derived from in situ evolution. (b) The other 18 endemics are taxa occurring in wider areas, so they cannot be generally considered “locally evolved” but relicts. This preliminary analysis confirms that not only continental (“chersogenous”) but all Mediterranean…
Lycopodiidae for the “Flora Critica d’Italia”: material and methods
2015
Procedures are presented that were followed during the preparation of the first pteridophyte family treatments for the “Flora Critica d’Italia”: Lycopodiaceae, Isoetaceae, Selaginellaceae. The work was mainly based on the study of literature and herbarium specimens. In some cases SEM observation of spores has proved useful. Data collected from herbarium specimens and other verified sources were loaded into a database, from which a distribution map was prepared for each taxon. Several preliminary papers have been published, and for each family a taxonomic conspectus, with type designations, maps and an identification key, has been prepared. The treatment of these three families for the “Flor…
Somatic embryogenesis and flow cytometric assessment of nuclear genetic stability for Sansevieria spp.: an approach for in vitro regeneration of orna…
2023
Sansevieria Thunb. species are traditionally known as succulent ornamental plants worldwide. They are also cultivated for medicinal, fodder, soil conservation and fiber uses, and for their capacity to reduce environmental pollution. Sansevieria sexual propagation is limited by the lack of viable seeds, and reproduction is largely made via vegetative propagation by suckers or cuttings. For these reasons, genetic improvement by conventional breeding is limited. To overcome this problem and to address the increasing demand from customers for novel Sansevieria varieties, many commercial companies regularly use in vitro propagation, as is the case in the breeding process of several ornamental pl…
