Vegetative propagation of forest trees offers advantages to both tree breeders and the forest industry. This review will describe benefits, type of vegetative propagation, and its integration into breeding programmes. Of all of the different methods for vegetative propagation, only rooted cuttings and somatic embryogenesis (and the combined use of both) offer any practical methods for large-scale commercial use. However, it is very difficult to fully appreciate the overall level of activity of the research and application of somatic embryogenesis of forest trees. Publications and reports only highlight a small fraction of the ongoing work. To this end, a survey was conducted across Europe (under EU Research Infrastructure Concerted Action "Treebreedex") to document the species involved, the state-of-the-art of somatic embryogenesis, its stage of development and its application in tree improvement programmes and to commercial forestry. The results of this survey are presented and discussed. In addition, this review presents the challenges (biological, economic, public acceptance and regulatory) and their relationships to European forestry. Finally, a strategy to promote the use of this technology is proposed. © 2013 Springer-Verlag Berlin Heidelberg. Source

The homogenization of international wine market led to a gradual impoverishment of the genetic pool. In fact, in several Spanish Quality Demarcations, the most frequent international varieties are replacing the local ones. As a result, minor varieties, perfectly adapted to the local environmental conditions, are nowadays at risk of extinction. The study of minor varieties could provide useful inputs to satisfy the demand for new and interesting wine products. This work aims at filling a gap in the existing literature, focusing on the aromatic potential of minor varieties. Here, the study of glycosidic volatile compounds and the evaluation of the influence of several variables on aroma composition were considered. Fifty-one glycosidic compounds were identified and quantified. The results revealed differences for glycosidic compounds according to cultivars, berry color, clone and sample origin. The inclusion or not of the cultivars in Quality Demarcation was also discussed. Moreover, the synthesis of some compounds involved in these differentiations seems to have a genetic component. The characterization of aromatic potential of several minor varieties, achieved for the first time, revealed that some of these (Argamusa, Quigat, Pampolat girat, Excursach, Gorgollasssa or Mandón) could represent an excellent option for winemaking and commercial offer diversification strategies, besides being important for these cultivars conservation. © 2011 Springer-Verlag.

A novel portable electronic nose is presented as a fast tool to differentiate traditional aged wines from artificial aged wines. The instrument we have developed for testing the wines is a general purpose wireless portable electronic nose base on micromechanical tin oxide sensors. This system may discriminate among the wine samples obtained with the different aging methods. © 2011 American Institute of Physics. Source

One of the most important challenges in the global market of wine production is to match the preferences of consumers with both wine sensorial characteristics and the growing interest in sociological and environmental aspects. Use of minor grapevines might be strong candidates to satisfy these emerging consumer requirements. However, the potential of most of these cultivars are unknown. The wine quality is difficult to assay, nevertheless quantitative and descriptive analyses are the most used methods in wine sensory characterisation.This study presents the sensory description of wines made from 18 local cultivars, which were analysed from two vintages. The influence of vintage, Denomination of Origin (DO) and agronomical parameters over sensorial attributes were assessed by 21 expert wine tasters. Some wines made from minor varieties were better scored by experts compared to the wines made from varieties allowed in Spanish DOs, underlining the oenological possibilities of these minor cultivar wines.Wine sensory analysis showed significant correlation between sensory attributes and agronomical parameters, with vegetative and productive agronomical parameters inversely influencing aroma and taste scored by experts. Our results suggest that the management of agricultural parameters has the potential to improve the wine quality. This study also highlights the interesting possibilities of the minor varieties in the wine market. © 2013 Elsevier Ltd. Source

Ampelographic descriptions, a set of 20 nuclear microsatellite loci (nuSSR), five chloroplast microsatellites (cSSR), as well as historical references have been used to identify 66 accessions of Vitis vinifera L. The plant material included major and minor varieties under risk of extinction, collected in the Balearic Islands, and now conserved in two germplasm repositories site in Spain. The 66 samples analyzed corresponded to 32 different genotypes, several unique genotypes were found, three of them remaining unknown. Some synonyms and homonyms were found in the Mediterranean basin, highlighting that the dispersal of some varieties are related with historical human movements and migrations occurred in three several periods, (1) around seventh century related to Islam expansion, (2) around thirteen to fifteenth centuries and (3) in the nineteenth century related to phylloxera crisis. Some parentages were identified, being the cultivar Callet Cas Concos a key variety in several crosses, confirming the high value of unknown varieties for parentage analysis. Several grouping methods confirm the existence of two gene pools. © 2011 Springer Science+Business Media B.V. Source
