Forner-Alcaide 5 and Forner-Alcaide 13: Two New Citrus Rootstocks Released in Spain
No full textThe search for new citrus rootstocks with better performance than those currently used is the major aim of the citrus industry in many countries. New diseases, the spread of known diseases, and citrus culture under different environmental conditions force the demand for new rootstocks. Carrizo citrange [Citrus sinensis (L.) Osb. x Poncirus trifoliata (L.) Raf.], the most used rootstock in Spain, frequently shows iron chlorosis and salinity problems. Other less common rootstocks, such as Cleopatra mandarin (C. reshniHort. ex Tan.), C. volkameriana Ten. & Pasq., Swingle citrumelo (C. paradisi Macf. x P. trifoliata), and C. macrophylla Wester, do not conveniently solve the problems. Forner-Alcaide 5 (F-A 5) and Forner-Alcaide 13 (F-A 13) are two interspecific hybrids obtained through traditional hybridization by the senior author in a program for breeding citrus rootstocks at the Instituto Valenciano de Investigaciones Agrarias (IVIA) in Moncada (Valencia), Spain. The goals of the breeding program were to obtain new rootstocks tolerant to CTV, salinity, and lime-induced chlorosis and resistant to Phytophthora sp.

Performance of Navel orange trees grafted onto two new dwarfing rootstocks (Forner-Alcaide 517 and Forner-Alcaide 418)
No full textThe aim of the present work was to study the performance of two new dwarfing citrus rootstocks (FornerAlcaide 517 and Forner-Alcaide 418) in comparison with Carrizo citrange. To carry out these experiments, rootstocks were budded with Navelina Navel orange scions. In young plants, rootstocks' size-controlling capacity was associated to their hydraulic conductance. In the case of Forner-Alcaide 418, lower hydraulic conductance was related to a smaller lumen area of root xylem vessels with respect to the other rootstocks. Also, hydraulic resistance of bud union segments of the stem was found to decrease with increasing vigour of plants grafted onto the different rootstocks. Furthermore, the graft union may provide resistance to sucrose transport in dwarfing rootstocks, as indicated by the reduced translocation of 13C-labelled photoassimilates from leaves to roots and reduced soluble sugar and starch concentrations under the graft union. This may result in a deficient carbohydrate supply to roots in dwarfing rootstocks, thereby stunting their growth. Accordingly, small root size and low hydraulic conductivity may cause water deficit in leaves during periods of high evaporative demand, inducing stomata! closure. This leads to a decrease in photosynthetic assimilation rate, which may affect plant growth negatively. These effects occur to a different extent in scions on both dwarfing rootstocks, appearing to be the cause of their reduced growth. Moreover, plants on both dwarfing rootstocks showed decreased translocation of 13 C-photoassimilates to roots, possibly contributing to higher availability of these compounds in the scion, and resulting in increased 13C transport towards the fruits. This effect could explain the higher yield efficiencies found in dwarfing rootstocks. A ten-year long field experiment, with trees grafted onto the three rootstocks, showed that FornerAlcaide 517 and Forner-Alcaide 418 induced lower canopy volumes and higher yield efficiencies than Carrizo citrange. In addition, our results show both dwarfing rootstocks produce good fruit quality, are suitable for high density plantings and can be cultured in alkaline soils. (C) 2014 Elsevier B.V.

Libri, cultura e lingua italiana nel Settecento a Dresda,
No full textSi presenta l'opera e la figura di Giacomo Pasqualetti che, unita alle altre che ricordate, ben esemplifica l’interesse diffuso presso la corte di Dresda per l’epistolografia italiana: non si trattava qui solo della presenza di alcuni manoscritti o di alcune stampe, ma di una vera e propria biblioteca italiana, e di stampatori che davano vita ad una fiorente produzione in lingua 'toscana', solo in parte legata alle rappresentazioni musicali. Sezione cospicua di questa biblioteca italiana era dedicata all’epistolografia: numerose erano infatti le raccolte a stampa di modelli epistolari, opere spesso citate anche nei manuali per scrivere lettere come quello di Pasqualetti. Ho cercato di illustrare brevemente il fenomeno con qualche esempio, ricollegandomi per alcuni aspetti alla ricerca, più ampia e tuttora in corso, iniziata e propiziata dagli studi di Maria Lieber
Aeneas Silvius Piccolomini: Literature as the art of mediation
No full textThe years of Enea Silvio Piccolomini’s cardinalate are among the most intense of his diplomatic activity. By analysing his letters from these years, many of which have remained unpublished, this chapter will shed light on the diplomatic and cultural strategies that Piccolomini followed in his work of mediating conflicts. The Cardinal of Siena sought, and in some cases succeeded, in finding compromise solutions between widely divergent economic, political or cultural positions. Piccolomini acted firstly through his extensive diplomatic network, built up during a period of difficult work first in the Emperor’s Secretariat and then in the service of Callixtus III. With the help of some little-known unpublished letters, this chapter will also try to show how the friendships that Piccolomini forged in those years were not only cemented by coincidental, economic or political interests, but, in some significant cases, by a shared cultural vision based on humanistic values. This cultural perspective made the intervention of the Cardinal of Siena more effective, thanks also to the rhetorical and communicative skills that came from the new linguistic and literary knowledge. In those years, Piccolomini’s literary and humanist approach was a kind of successful model for diplomatic mediation in political, religious and cultural crises
