Anther Culture Effectiveness in Producing Doubled Haploids of Cereals/ Putekðòu Kultûras Efektivitâte Graudaugu Dubultoto Haploîdu Izveidoðanâ
2014
Abstract Our goal was to improve the method of obtaining double haploids (DH) by anther culture from Latvian breeding material for several agriculturally important cereals in Latvia: barley, spring and winter wheat. Hybrids from Latvian breeders were initial material. It was found that copper (2.5 mg/l) added to barley anther pre-treatment media and to both barley (C3) and wheat (liquid AMC) induction media, resulted in a higher percentage of green plants-regenerants. In general, the winter wheat hybrids exhibited lower embryogenesis than spring wheat hybrids. Obtaining a large number of DH lines from barley and wheat hybrids with unknown androgenesis response can be organized in two stages…

Annullamento del testamento per dolo e incapacità naturale: uno sguardo comparatistico
2018
Il contributo analizza le questioni connesse all’annullamento del testamento per dolo e incapacità naturale. Risultando piuttosto restrittivo l’attuale orientamento in tema di prova della mancanza di capacità testamentaria e della captazione, è necessario proporre delle soluzioni alternative, anche mediante il confronto con l’Inghilterra e gli Stati Uniti. Quanto all’art. 591, comma 2°, n. 3, cod. civ., si potrebbe attribuire rilievo non solo all’incapacità totale, bensì anche a quella parziale (come avviene per gli atti inter vivos). Quanto, invece, all’art. 624 cod. civ., si deve prendere in considerazione, ai fini dell’annullamento, dolo e captazione “attenuati”, nel caso in cui, se valu…
Testaments et pratique testamentaire dans le royaume franc (vie-viiie siècle)
2005
Les testaments merovingiens ont de longue date attire l'attention des diplomaties, des historiens du droit et de la societe. U. Nonn a montre la continuite entre testaments romains et merovingiens, mais on s'interroge toujours sur la diffusion de ces actes dans la societe et sur les conditions de leur disparition au IX e siecle. Un reexamen de la question (avec listes du materiel disponible) donne a penser que differents types d'actes a cause de mort etaient utilises dans la societe merovingienne et que les testaments aristocratiques - les seuls connus-, conserves de maniere preferentielle par les heritiers ecclesiastiques qu'ils instituaient, ne sont pas representatifs d'une pratique sans …
Anther culture in Citrus clementina: a way to regenerate tri-haploids
2005
Abstract. Regenerants from anther culture of Citrus clementina Hort. ex Tan. cvv. Nules, SRA 63, and Monreal were obtained in different experiments from 1994 to 2002. Genetic analysis of 37 such regenerants was carried out using 4 microsatellite markers that were heterozygous in the parental genotypes. The results showed that in all cases but one the regenerants carried only one or the other allele of the parental genotype, and were therefore homozygous and produced through a process of gametophytic embryogenesis. Ploidy analysis by flow cytometry of 94 regenerants showed that as many as 82% of them were tri-haploids, rather than haploids or doubled-haploids as expected, with other ploidy …
ANDREA GIACOBBE, UN SELVICOLTORE CHE MERITA DI USCIRE DALL'OBLIO
2021
Andrea Giacobbe, a forester who deserves to get out from oblivion. The scientific production of Andrea Giacobbe, a Sicilian forester who worked in central and northern Italy in the last century, has been revisited. The aim is to highlights how his contribution to botany, forest ecology and forestry has been largely overlooked. He was the protagonist of a lively debate with the greatest for est scientists of his time, he produced 64 papers and books, but above all he proposed many inno vative reforestation techniques that today should be rediscovered and applied.
Forest Sharing® as an Innovative Facility for Sustainable Forest Management of Fragmented Forest Properties: First Results of Its Implementation
2023
The forestry sector in Italy and throughout Europe is going through a critical period due to ongoing natural and anthropological processes, such as climate change and the abandonment of rural areas. These processes lead to a constant fragmentation of properties in small forest parcels, with direct impacts on management capacity. In this framework, new sustainable forest management methods are being tested and are shown to be good practices to oppose the decline of forest ecosystems. Their innovative aspects concern the introduction of a form of shared and circular economy, where management is built on the process, rather than on the product. Their technical activities are based on precision…

Advanced earth observation approach for multiscale forest ecosystem services modeling and mapping (MIMOSE)
2014
In the last decade ecosystem services (ES) have been proposed as a method for quantifying the multifunctional role of forest ecosystems. Their spatial distribution on large areas is frequently limited by the lack of information, because field data collection with traditional methods requires much effort in terms of time and cost. In this contribution we propose a methodology (namely, MultIscale Mapping Of ecoSystem servicEs - MIMOSE) based on the integration of remotely sensed images and field observation to produce a wall-to-wall geodatabase of forest parcels accompanied with several information useful as a basis for future trade-off analysis of different ES. Here, we present the applicat…
L’apporto del diritto canonico nella disciplina delle pie volontà fiduciarie testamentarie del diritto inglese
2008
L’interesse per i legami tra diritto canonico e diritto inglese nasce dalla constatazione dell’ingiustificato oblio in cui per lungo tempo sono caduti gli studi sui rapporti intercorsi tra Stato e Chiesa cattolica in Inghilterra prima della riforma anglicana. La causa della disaffezione verso tale settore del diritto ecclesiastico comparato è, forse, imputabile alla drastica cesura causata dallo scisma anglicano, tale da far dimenticare che fino al 1534 la Chiesa d’Inghilterra faceva parte integrante dell’Orbe cattolico, con relazioni e conseguenti scambi culturali e giuridici. A ciò si è aggiunto il ben noto orgoglio inglese che ha preteso di tracciare una netta linea di demarcazione, non …
