Fruiting, Morphology, and Architecture of ‘Arbequina’ and ‘Calatina’ Olive Branches

2022

Two different olive cultivars grown under a high-density hedgerow system were studied to compare their fruiting and branch architecture features and to determine the possibility to use ‘Calatina’ olive trees for intensive plantings, as a local alternative to the international reference ‘Arbequina’. Weights of two-year-old branches, fruits and leaves were recorded to estimate the growth partitioning. Growth and architectural parameters, such as shoot length, vector and diameter, branching angle, branch total length, height, width, area, and branching frequency, were determined by digital image analysis. Digital images of the fruits were also used to estimate fruit maturation by peel color an…

Use of chemical treatments to reduce browning color of white fresh-cut peaches, harvested in summer and late crop

2022

Fresh-cut white peach is very perishable and discoloration or browning are the main factors affecting consumer acceptability loss. Color and appearance attract the consumer to a product and can help in impulse purchase. The aim of this study was to investigate the effect of two different edible coatings formulations in preserving freshcut fruit of the early ripening ‘Murtiddara’ and the late ripening ‘Settembrina’ peach landraces, belonging to the ‘Pesca di Bivona’ varietal population. Fruit sampled at commercial harvest stage, after cutting and dipping in different solutions with ascorbate calcium (ASC) and hydroxypropyl methylcellulose (HPMC) were stored for 3, 5, 7 and 12 days at 5°C and…

STUDY ON GAMETIC EMBRYOGENESIS VIA IN VITRO ANTHER AND ISOLATED MICROSPORE CULTURE IN FRUIT CROPS

2014

Fruit breeding is mainly based on both conventional (hybridization, mutation and selection) or biotechnological methods (somatic hybridization, genetic transformation and haploid production). The genetic improvement through the conventional methods is limited by many factors such as fruit trees long juvenile period, high heterozygosity, large size and sexual incompatibility. Haploids and doubled haploids, obtained through gametic embryogenesis have a potential use in fruit crops genetic improvement. The change of the microspores fate from the normal gametopytic pathway towards the sporophytic induction is affected by numerous factors. Genotype, medium composition and stress were considered …

Consumer Assessment on Sensory Attributes of Fresh Table Grapes Cv 'Italia' and 'Red Globe' after Long Cold Storage Treatment

2017

The impact of research that is being carried out into the relationship between food and consumers is progressively reinforced by continuous findings in literature confirming that consumers choose foods basing on their functional cognition and sensory perception, especially when buying fruit and vegetables. Therefore, it is important for table grape producers to be aware of consumers' concerns and preferences both, during the purchasing stage and after, during consumption at home, when experiential attributes have more importance. In both cases, sensory attributes play an important role in determining consumers’ purchase behavior of table grape. Table grapes cv ‘Italia’ and ‘Red Globe’ are p…

High quality extra virgin olive oil from olives attacked by the olive fruit fly, Bactrocera oleae (Rossi) (Diptera Tephritidae): which is the tolerab…

2017

The infestation due to the olive fruit fly, Bactrocera oleae (Rossi), the key pest in most of world olive groves, has been monitored in six years, from 2004 to 2008 and in 2014, in eight coastal Sicilian olive groves consisting of ‘Cerasuola’ and ‘Nocellara del Belice’ cultivars. Infestation was recorded following the classical sampling method based on olive collection and dissection, in order to count live olive fruit fly instars (eggs, larvae and pupae) and exit holes. Four different infestation indexes, all of them calculated using data recorded at harvest, have been used to assess their relationship with the main three quality parameters of the olive oil obtained from the same olive sam…

VALIDACIÓN Y CALIBRACIÓN DE UN MODELO EPIDEMIOLÓGICO PARA PREDECIR EL MOTEADO DEL NÍSPERO CAUSADO POR Fusicladium eriobotryae EN SICILIA

2016

El moteado del níspero causado por Fusicladium eriobotryaees la principal enfermedad de este cultivo en la cuenca mediterránea, afectando principalmente a hojas y frutos. Recientemente, la biología del patógeno y la epidemiología de la enfermedad han sido estudiadas en profundidad, y los resultados obtenidos han permitido el desarrollo de un modelo epidemiológico “EriScab”, capaz de predecir la infección de frutos por conidios de F. eriobotryae. Este modelo, que utiliza como inputs variables meteorológicas, ha sido validado en la principal zona de cultivo de la provincia de Alicante, Callosa d’En Sarrià, sobre frutos de la variedad Algerie. El objetivo de este trabajo es: (i) evaluar la rob…

Instrumental and sensory analysis of eating quality of peaches and nectarines

2010

The influence of flesh firmness on consumer acceptance and its relationship with total soluble solids concentration (TSSC), titratable acidity (TTA) and sensory analysis was studied to understand their interaction in determining acceptance judgments, for different organoleptic typologies of peaches and nectarines. The investigation was carried out during summer 2006 on fruit of ‘September Sun’ and ‘Sweet September’ (low acid) peach (Prunus persica (L.) Batsch), and ‘Maria Dolce’ (low acid) and ‘Venus’ nectarines (Prunus persica (L.) Batsch, var. nucipersica). Sensory descriptors for peaches and nectarines were Flesh firmness, Sweetness, Sourness, Aroma, and Acceptability. The panel was able…

Posidonia Oceanica And Green Tea Extract As Active Agents For Shelf Life Extension Of Fresh Cut Peach

2015

Nowadays the reduction of food waste and the availability of food all over the world areas are priority keys for society. In this context, the shelf life extension of fresh products in a sustainable way may represent one of the main goals. The aim of the present research work was to extend the shelf life of fresh cut peach slices by using extracts of Posidonia oceanica (POS) and green tea (GT), and compared to the control. Total polyphenols content was assessed by Folin-Ciocalteu method and the antioxidant capacity by DPPH (2,2-Diphenyl-1-Picrylhydrazyl) assay. Antimicrobial activity of the two extracts was initially carried out in vitro by determining the Minimal Inhibitory Concentration (…

Plant-based water stress sensing in two olive cultivars with different physiological responses to drought

2022

A large portion of modern olive plantings is dominated by one main cultivar (‘Arbequina’) planted at super high density (SHD, 1,500 tree ha‑1), leading to a dangerous reduction in olive biodiversity. Very few cultivars have growth and productive patterns that suit the SHD system requirements. Partial intensification and mechanization with several cultivars may represent the safest and easiest alternative. The efficient use of limited natural resources, such as water, in SHD systems, requires precise management. Continuous plant-based sensing is a promising approach to managing water, mainly tested on the cultivar ‘Arbequina’. In this study, we evaluated the sensitivity of two promising indi…
