Micropropagation of Globe Artichoke (Cynara cardunculus L. var. scolymus).

2013

The globe artichoke (Cynara cardunculus L. var. scolymus) is a perennial plant cultivated in the Mediterranean region and the Americas for its edible young flower heads. Although vegetative propagation by offshoots or by “ovoli” (underground dormant axillary buds) has been the primary method of propagation, the potential for the diffusion of diseases and the phenotypic variability can be very high. The propagation of this species by axillary shoot proliferation from in vitro cultured meristems produces systemic pathogen free plants and a higher multiplication rate as compared to that obtained by conventional agamic multiplication. Axillary shoot proliferation can be induced from excised sho…

LE SPECIE DELLA FLORA VASCOLARE SICILIANA INCLUSE NELLE NORMATIVE INTERNAZIONALI

2012

Species of sicilian vascular flora included in the international laws. The present paper aims to divulgate the knowledge of the Sicilian flora protected at international level and includes a check-list of the Sicilian vascular flora recorded in international normatives on the protection of nature and biodiversity. For each normative general information is given together with a reference list to further deepen the contents, the aims and the present implementation in Italy.

Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo.

"Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo". Lilloa 53 (2). Plantas del endemismo Lamottea diania se expusieron en cámaras OTC (Open Top Chambers) a aire ambiente filtrado y a aire ambiente no filtrado más 30 ppb de ozono para observar el efecto de este contaminante sobre el desarrollo de sus flores, particularmente sobre su androceo. Hemos comprobado, mediante estudios de microscopía óptica y electrónica, que el ozono afecta el proceso de desarrollo y maduración de los estambres y del polen. Las anteras se ven afectadas, en unos casos al abortar algunos estambres en su desarrollo y, en …

Microbial Diversity in the Midguts of Field and Lab-Reared Populations of the European Corn Borer Ostrinia nubilalis

2011

Background: Insects are associated with microorganisms that contribute to the digestion and processing of nutrients. The European Corn Borer (ECB) is a moth present world-wide, causing severe economical damage as a pest on corn and other crops. In the present work, we give a detailed view of the complexity of the microorganisms forming the ECB midgut microbiota with the objective of comparing the biodiversity of the midgut-associated microbiota and explore their potential as a source of genes and enzymes with biotechnological applications. Methodological/Principal Findings: A high-throughput sequencing approach has been used to identify bacterial species, genes and metabolic pathways, parti…

The taxonomy of Galium crespianum J.J. Rodr. (Rubiaceae), a Balearic Islands endemic revisited

2001

Abstract Galium crespianum J.J. Rodr. is a perennial plant inhabiting cliffs and crevices on the Balearic Islands. Although it was described from the mountains of Mallorca, several populations from the islands of Eivissa and Formentera have been traditionally considered as belonging to the same species. A careful comparison of specimens from the western and eastern Balearics revealed several discriminant features in gross morphology (robustness and habit of the stems, presence or absence of hairs at the internodes and leaves, waxiness of stems and leaves, shape of the inflorescence, flower colour and scent) and stem anatomy. In addition, several mutations in the ribosomal ITS sequences dist…

Microbial and chemical changes in 'Sobrasada' during ripening.

1993

‘Sobrasada’ is a raw-cured product typical of Mallorca (Balearic Islands). Throughout its ripening process the product, like other raw-cured sausages, undergoes a series of chemical and microbial changes which lead to the formation of its desirable final characteristics. In the ‘sobrasada’ studied, the breeds, feeding and casings used in the Balearic Islands were employed. The evolution of different groups of microorganisms was followed: mesophylic aerobic microorganisms, lactic acid bacteria, Enterobacteriaceae, yeasts and moulds, group D Streptococcus, proteolytic microorganisms and lipolytic microorganisms. It was found that the predominant flora, from the beginning to the end, was made …

A new Biscutella (Brassicaceae) species from the western Balearic Islands

1999

Abstract A new diploid species, Biscutella ebusitana is described from coastal cliffs of the western Balearic islands. It is related to B. sempervirens L. and B. montana Cav. from which it can be distinguished by a combination of vegetative (shape, size, petiole and hairs of leaves, petiolate leaves) and reproductive features (shape of inflorescence, calyx indument). Earlier Balearic records of B. frutescens Coss. should be referred to B. ebusitana .

Effect of Nitrogen Fertilization on the Quality of Swiss Chard at Harvest and during Storage as Minimally Processed Produce

2014

The effects of different levels of nitrogen fertilization (0-50-100-150-200 kg ha-1), minimal processing and cold storage (14 days at 4°C) on yield and quality of fresh-cut Swiss Chard (Beta vulgaris L. var. cicla L.) were evaluated. Increasing the level of nitrogen fertilization over 100 kg N ha-1, plants had a higher fresh weight, reduced their dry matter content and resulted taller and leafier. Total and marketable yield increased linearly as increasing nitrogen level. Both nitrate and ascorbic acid content at harvest increased as increasing nitrogen supply. Nitrogen fertilization negatively affected the yield of minimal processing. No effect on appearance and quality loss during cold st…
