The role of mucilage of Opuntia ficus-indica Mill. on sweet cherry fruit during storage
2022
Sweet cherry (Prunus avium L.) is an important crop from temperate areas and is widespread and much appreciated by the consumers when the pedicel is green. The objective of this work was to evaluate the quality of sweet cherry fruit treated with a mucilage coating, extracted from cladodes of Opuntia ficus-indica L. Mill (OFI). The cultivar ‘Ferrovia’ was harvested at the commercial ripeness stage from an orchard in Puglia (Italy), stored for 14 days at 2°C and RH 92% and to evaluated by the variation of color and other qualitative parameters such as physical-chemical, nutraceutical and sensory analysis. Fruits were transferred at 10°C to postharvest laboratory of University of Palermo after…
Preliminary evaluation of sixPrunusrootstocks for peach in Italy
2018
In Italy, the evaluation of rootstocks is supported by the Ministry of Agriculture and carried out in a network of trials along the Country. This study evaluated growth and yield performance of ‘Big Top’ nectarine and ‘Rome Star’ peach grafted on six rootstocks of different origin and vigor, namely GF677 (the most widespread in Italy), Garnem, Adesoto, RootPac®20, RootPac®40, and RootPac®90, in three different locations, Castelvetrano (Sicily), Forlì and Cesena (Emilia-Romagna). Yield, number of fruits, trunk cross-sectional area (TCSA), average fruit weight, flesh firmness, soluble solids content (SSC) and titratable acidity (TA) were determined at the third leaf (2015). In all sites, tree…
Use of phenoclimatic models to estimate the chill and heat requirements of four sweet cherry cultivars in Italy
2017
During their dormant period, fruit trees require a certain amount of relatively low temperatures to complete bud differentiation processes and regularly resume growth the following spring. Unsatisfied chilling needs can result in delayed foliation, severe yield and fruit quality losses. There is a need for a method to estimate accurately the chilling requirement of a cultivar. This is especially important in those areas where the potential of chill accumulation in winter is low and for those crops, such as sweet cherry, which generally have a high chilling requirement. Historical temperature records and blooming dates of four sweet cherry cultivars widely cultivated in Italy - 'Burlat', 'Sw…
Frigoconservazione ed edible coating per la conservazione post-raccolta dei frutti della pesca Settembrina
2018
Da quanto emerso dai dati strumentali, l’applicazione del rivestimento a base di Aloe sui frutti di pesca “Settembrina”, sia in maniera singola che congiunta con 1 MCP, consente di rallentare i processi metabolici, permettendo, quindi, il mantenimento del colore dei frutti nel tempo e prevenendo la degradazione di tutti i composti nutrizionali e bioattivi utili a conferire al frutto serbevolezza e pregevoli caratteristiche organolettiche. Quanto riscontrato, si potrebbe tradurre in un vantaggio per il produttore che, usufruendo di una tecnologia semplice ed ecosostenibile dal punto di vista ambientale, potrebbe offrire al consumatore frutti dalla elevata shelf life con elevati standard qual…
ANALISI BIOMETRICA DI VARIETA’ DI MORUS ALBA AI FINI DELLA IDENTIFICAZIONE E CLASSI- FICAZIONE
2014
Per gli storici c’è ancora una polemica circa l’origine ed il tempo della prima introduzione del gelso in Italia. Molti sono d’accordo che le due principali specie di gelso (Morus alba e M. nigra) provengono dall’Asia, la prima dalla Persia e la seconda dal lontano est. Sembra, comunque, che sia stato il gelso nero (Morus nigra) il primo ad essere adattato e coltivato per i suoi frutti, non solo a fini alimentari ma anche per scopi medicinali dai Greci e dai Romani (Bertelli Bargamaschi, 1994). Il gelso bianco, originario della Cina, è stato introdotto in occidente assieme al baco da seta nel XII secolo. La grande importanza del gelso bianco derivava infatti dal fatto che questo era un alim…
The Use of Opuntia ficus-indica Mucilage and Aloe arborescens as Edible Coatings to Improve the Physical, Chemical, and Microbiological Properties of…
2022
Edible coatings (EC) with mucilage of Opuntia ficus-indica or Aloe arborescens are promising to extend the shelf life of fresh-cut fruit products by reducing weight loss and microbial spoilage. In this work, fresh-cut kiwifruits (cv. Hayward) were coated in solutions with mucilage extracted from Opuntia ficus-indica (MC) and A. arborescens (AL). We used three alternative treatments with AL or MC, MC+AL, and with distilled water as control, and stored in passive atmosphere at 5 °C for 3, 5, 7, and 9 d, respectively. For all treatments at each storage period, firmness, weight loss, color, visual quality score, respiration rate, pectin content, and microbiological characteristics were observed…
Yield and profitability of modified spanish bush and Y-trellis training systems for peach
2015
Peach trees trained to modified Spanish bush (MSB) and Y-trellis (Y) were evaluated and compared in the Mediterranean settings of Southern Italy. The observations included two peach (Rich May and Summer Rich) and two nectarine (Big Bang and Nectaross) cultivars. In the MSB system, trees were spaced at 4.5 x 2.5 m (888 trees/ha), whereas in the Y system, trees were spaced at 5.5 x 2 m (909 trees/ha). Costs at planting, yield per tree, fruit size grade, unit price of sold peaches for each size grade, amount and cost of materials and labor for cultural management, and grower's profit were quantified throughout all six years from planting and at full crop (year 4-6). Fixed costs of the MSB syst…
