Fruit tree orchard establishment

2019

The agronomic and economic success of a fruit-tree orchard is mainly determined by the choices made by the grower during the planting stage. A distinctive feature of fruit tree orchards is the very high investment cost for their establishment and the fluctuations in the revenue stream over their lifetime. Growers do not immediately make a profit after planting, and their success depends on the proper choice of fruit tree species, on orchard design and on the specific goals they choose to pursue. Moreover, profitability will also depend on a careful analysis of the economic, environmental, technological, social and infrastructural (transportation system, energetic resources, supply chain log…

Study of energetic properties of different tree organs in six Olea europaea L. cultivars

2021

AbstractPruning is an important horticultural practice for the management of olive orchards (Olea europaea L.) that generates a considerable amount of residues every year. Olive orchards are increasingly expanding beyond the Mediterranean Basin to new growing Countries (Australia, California, Argentina, Chile and Uruguay) and this will certainly lead to larger availability of pruning material. Currently, the interest in use of olive tree pruning residues for energy purposes is increasing but unfortunately, the information on the differences among organs of the tree, in terms of calorific value and ash content, is scarce. Another unknown aspect is the effect of cultivar vigour on dry matter …

Assessment of the Vegetation Parameters of Almond and Vine Plants for Designing a Compact Tractor

2018

The aim of this research is to assess the vegetation parameters of almond and vine plants, aimed at designing a compact tractor suitable for these orchards. The research is part of the Italian project TRACLAS, involving the Universities of Palermo, Milan, Bari, “Tuscia” of Viterbo and Agricultural Research and Economics - Research Unit for Agricultural Engineering (CREA-ING) of Treviglio (Bergamo). Based on the results of the surveys carried out in a sample of almond and vine farms, it was possible to define the vegetation parameters that will allow to design a very low and narrow tractor equipped with a fixed ROPS and suitable for these orchards.

First data on the repellent activity of essential oils of Citrus limon towards medfly (Ceratitis capitata)

2012

The biological activity of peel essential oils of two Sicilian cultivars of C. limon, ‘Interdonato’ and ‘Lunario’, was investigated by electrophysiological recordings (EAG) and field trials on Ceratitis capitata (Wiedemann) (Diptera Tephritidae). The EAG data showed a remarkable dose-response relationship and a low activation threshold dose (10-3M) for both essential oil extracts. In field tests, essential oils showed a good repellent and antiovipositional activi- ty on ‘Navelina’ oranges, and in particular the essential oils of ‘Lunario’ pro- vided the same results of kaolin. Potential applications of essential oils from C. limon cultivars against C. capitata in organic farming are discuss…

Primi studi sulla biologia e sul controllo di Cydia funebrana (Treitschke) in susineti biologici siciliani

2011

First studies on biology and control of Cydia funebrana (treitschke) in Sicilian organic plum orchards. Cydia funebrana (Treitschke), considered the key pest in the Sicilian plum orchards. Few studies were carried out in Sicily concerning C. funebrana life cycle, forecasting models and the effectiveness of some products permitted in organic plum orchards. In 2010 researches were carried out in three Sicilian plum orchards, two in Palermo Province (Monreale and San Giuseppe Jato) and one in Agrigento Province (Castrofilippo), in order to monitor the population, to evaluate damage levels caused by the plum moth and to estimate how many generations it could complete by Charmillot’s forecasting…

Lava ribollente nel sottosuolo. Il Čechov di Visconti nella cultura italiana del Novecento

2021

Anton Chekhov is one of the most emblematic figures in the history of theatre. His plays were among the most frequently performed plays during the Twentieth century. The reception of his plays has forged a theatrical genotype that would have led to misunderstandings or altered his assimilation in an instrumental way. But it is in the very nature of the theatre to provoke, disorient, wink, mock, etc., in order to increase the audience’s attention. The lines of Trofimov from The Cherry Orchard have engraved an indelible mark in the audiences of an entire century and beyond, like a boiling lava. Through the analysis of different productions of Chekhov’s plays on various stages, the essay highl…

Canopy Architecture Appraisal by Fractal Dimension of 'Flordastar' Peach Trees Grafted onto Different Rootstocks

2007

The objective of this research was to evaluate the modification of canopy architecture of ''Flordastar'' peach (Prunus persica L. Batsch) grafted onto rootstocks with different vigour, by the use of fractal dimension (D). The hypothesis was that different vigour rootstocks are able to modify the complexity of the branching pattern and that this effect can be assessed by a geometric parameter such as the fractal dimension (D) of the 2D projection of tree branching structure. The observations were carried out in a four-year-old experimental orchard of cv. ''Flordastar'' peach trees grafted onto Ishtara, Barrier, GF677 and MrS 2/5 rootstocks. On digital pictures of leafless, dormant peach tree…
