Characterization of five sour orange clones through molecular markers and leaf essential oils analysis.

2006

Five clones of sour orange (Citrus aurantium L.) showing significant morphological differences were selected from our germplasm collection and characterized both by genetic and leaf volatiles analysis. The genetic studies were undertaken by the use of molecular markers developed by PCR-based techniques (ISSR and RAPD), while the leaf essential oil patterns were obtained by chromatographic and mass spectrometric determination. Data obtained suggest that reasonably similar information can be achieved from the two techniques, supporting each other in characterization studies.

Information Greater than Mobilisation Greater than Interaction: Contours of a Pan-European Style of Social Media Campaigning

2021

This chapter compares the Facebook campaigns of 90 political parties aggregated by the political groups in the EP to which they belong from 12 countries in the 2019 EP election. Based on these results we identify the contours of a pan-European style of social media campaigning that can be described as follows: national contexts dominated and framed the EP elections. In comparison to the three key functions of election campaigns, parties place the most importance by far on information in their use of social media. Calls for mobilisation play a certain role, while the parties seem hardly interested in interactions. The ongoing neglect of social media’s interactive potential in politics calls …

Construyendo comunes para el derecho a la ciudad a través de la innovación social colectiva en la distribución y consumo: explorando un marco concept…

2022

En la actual crisis urbana, el nuevo municipalismo reclama la reconstrucción de comunes urbanos para avanzar en el derecho a la ciudad. Señala al respecto la importancia de los movimientos sociales y de la acción pública municipal para generar procesos de innovación social “desde abajo”. Sin embargo, no se ha explorado suficientemente la literatura sobre innovación social con miras a comprender la construcción de comunes urbanos. Por ello, este trabajo propone, a partir de la literatura sobre innovación social de base, un marco para explorar prácticas de generación de comunes desde la ciudadanía, así como políticas municipales que pueden articularse para apoyarlas. El marco se emplea para e…

Triterpenoid saponins from the roots of two Gypsophila species.

2013

Two triterpenoid saponins with two known ones have been isolated from the roots of Gypsophila arrostii var. nebulosa, and two new ones from the roots of Gypsophila bicolor. Their structures were established by extensive NMR and mass spectroscopic techniques as 3-O-β-d-galactopyranosyl-(1→2)-[β-d-xylopyranosyl-(1→3)]-β-d-glucuronopyranosylquillaic acid 28-O-β-d-xylopyranosyl-(1→4)-[β-d-glucopyranosyl-(1→3)]-α-l-rhamnopyranosyl-(1→2)-[β-d-glucopyranosyl-(1→4)]-β-d-fucopyranosyl ester (1), 3-O-β-d-galactopyranosyl-(1→2)-[β-d-xylopyranosyl-(1→3)]-β-d-glucuronopyranosylgypsogenin 28-O-β-d-xylopyranosyl-(1→4)-[β-d-glucopyranosyl-(1→3)]-α-l-rhamnopyranosyl-(1→2)-[β-d-glucopyranosyl-(1→4)]-β-d-fuco…

Root Canal Morphology and Configuration of the Mandibular Canine: A Systematic Review

2021

The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), w…

A comparative analysis of genetic variation in rootstocks and scions of old olive trees – a window into the history of olive cultivation practices an…

2014

Background Past clonal propagation of olive trees is intimately linked to grafting. However, evidence on grafting in ancient trees is scarce, and not much is known about the source of plant material used for rootstocks. Here, the Simple Sequence Repeat (SSR) marker technique was used to study genetic diversity of rootstocks and scions in ancient olive trees from the Levant and its implications for past cultivation of olives. Leaf samples were collected from tree canopies (scions) and shoots growing from the trunk base (suckers). A total of 310 trees were sampled in 32 groves and analyzed with 14 SSR markers. Results In 82.7% of the trees in which both scion and suckers could be genotyped, t…

Mi.P.A.F. targeted project for evaluation of European and Japanese plum rootstocks in Italy: Results of six years of observations

2007

The Mi.P.A.F. (Italian Ministry of Agriculture) targeted project "National Lists of Recommended Rootstocks and Cultivars", coordinated by Prof. F. Loreti, University of Pisa, aims at evaluating the performance of fruit rootstocks introduced into the Italian nursery market. As part of this project, trials were established to compare some of the most interesting rootstocks for European and Japanese plum in 9 different locations in Italy. The rootstocks tested were: 'Citation-Zaipime', 'GF 31', 'Marianna GF 8/1', 'Ishtara-Ferciana', 'Jaspi-Fereley', 'Julior-Ferdor', 'Myrobalan 29C', 'Myrobalan B', 'MrS 2/5' and 'Myrocal'. In 1995, nine orchards were planted at 5 × 5 m spacing; in each orchard,…

Present status of Phytophthora species in the Mediterranean area, especially in relation to citrus

1990

Of the 44 currently accepted species of Phytophthora, 18 have been reported in the Mediterranean area. The status of each is briefly reviewed. On citrus, P. citrophthora and P. nicotianae var. parasitica are mainly responsible for foot rot and gummosis, and in addition P. hibernalis, P. syringae, P. cifricola and P. cactorum for brown rot of fruits. The incidence of these species is closely linked to their temperature requirements. The use of sour orange as a resistant rootstock has long provided satisfactory control of foot rot and gummosis, while chemical treatments are effective against brown rot. However, there are indications that, with changingcultural practices, the resistance of sou…

Dynamics of dry matter partitioning in young ‘Nocellara del Belice’ olive trees

2008

Dry matter partitioning of ‘Nocellara del Belice’ olive (Olea europaea L.) trees was assessed during one growing season. Four three-year-old potted trees from rooted cuttings trained to single-trunk free-canopy were destructively harvested at 30-day intervals during the growing season. The average dry matter increase was about 2 kg · year-1 per tree. Total plant dry weight increased linearly over the year, whereas root to shoot ratio followed a quadratic trend with its peak during winter. Dry matter of all canopy parts (trunk, branches, 1-year-old shoots, and leaves) increased linearly and leaves exhibited the fastest growth. Also fine roots accumulated dry matter over the year in a linear …
