Properties of New Strawberry Lines Compared with Well-Known Cultivars in Winter Planting System Conditions

2017

In Southern Italy and Sicily, strawberry cultivation is dominated by international cultivars such as ‘Candonga Sabrosa’, ‘Florida Fortuna’, ‘Sabrina’ and ‘Sant Andreas’. The primary objective of our study was to compare the field performance of two experimental lines and four established cultivars in a Sicilian representative strawberry production area. The second objective was to compare the fruits physic-chemical nutraceutical characteristics of these genotypes in response to different postharvest fruit storage temperatures. A supporting genetic analysis, via SSR markers, was also performed in order to establish genotype correlations. Our study confirmed the high result of ‘Florida Fortun…

Environmental and genotype effects on the fruits quality and nutritional traits of wood strawberry in Sicily

2012

In Sicily, the common woodland strawberry (Fragaria vesca) is spontaneous in the Madonie Mountains (554 m a.s.l.), Nebrodi Mountains (850 m) and Mount Etna (900 m). In this region, the main clone cultivated is 'Fragolina di Sciacca e Ribera', named after the towns where the crop originally developed. It is a Junebearing genotype and it is characterized by very small fruits, globose-conical shape, deep red colour, very soft flesh, strong aroma and flavor. Also ever-bearing clones are cultivated in Sicily where they are cropped for many months. Solid soluble content, total titratable acidity, total antioxidant capacity, total polyphenols and anthocyanins content were quantified in berry sampl…

Soil Solarization as an Alternative to Methyl Bromide Fumigation for Annual Strawberry Production in a Mediterranean Area

2008

This study compares the effects of soil solarization and methyl bromide fumigation on the growth and yield of strawberry plants (Fragaria xananassa Duch.) cultivated under plastic tunnel conditions. The study was conducted in a Mediterranean coastal area, in four consecutive annual production cycles in a field with no history of methyl bromide fumigation and 2-year history of strawberry production. In all 4 years, solarization was conducted for 7- to 9-week intervals from late June to early September. Cultivar Tudla frigo-plants were planted through mulch in the first week of September of each year. Average daily soil temperatures in solarized plots measured at 15 cm depth were 6.0, 8.1, 7.…

Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport

2016

Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria x ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…

Evaluation of quality parameters of strawberry fruits in modified atmosphere packaging during storage

2010

The objective of the present study is to evaluate the effect of modified atmosphere packaging (MAP) during storage on some quality parameters of strawberries. Strawberries (cv. Camarosa) were harvested when mature, forced air cooled and divided into two groups as fruits in MAP and control. After packaging, fruits were stored at 0°C, 90 - 95% RH for 10 days plus 1 day at 20°C and 50 - 55% RH for the evaluation of shelf life. Changes in fruit quality, mass loss, decay, color, firmness, total soluble solids (TSS), acidity, glucose, fructose, saccharose and color were investigated. The mass loss and decay were lower in MAP than observed in the control whereas firmness, TSS, acidity and color di…

Strawberry Variety Trial in Sicily.

2013

The Sicilian strawberry area differs from other Italian strawberry areas for its high earliness with productions that start in November-December. The earliness due to the very low plant winter chilling requirement is a very important characteristic to define the variety adaptability to this environment. Through the "Liste varietali Fragola" project funded by MiPAAF, many new varieties and advanced selections are evaluated annually in Sicily. Here, at the moment, the main variety is Florida Fortuna, followed by Candonga ® Sabrosa and Naiad ® CIVL35. Florida Fortuna, released in Florida, showed to be very interesting especially for its outstanding earliness, a high yield and good fruit qualit…

Simple Sequence Repeat Marker Development and Mapping Targeted to Previously Unmapped Regions of the Strawberry Genome Sequence

2011

The genome sequence of the woodland strawberry (Fragaria vesca L.) is an important resource providing a reference for comparative genomics studies and future sequenced rosaceous species and has great utility as a model for the development of markers for mapping in the cultivated strawberry Fragaria ×ananassa Duchesne ex Rozier. A set of 152 microsatellite simple sequence repeat (SSR) primer pairs was developed and mapped, along with 42 previously published but unmapped SSRs, permitting the precise assignment of 28.2 Mbp of previously unanchored genome sequence scaffolds (13% of the F. vesca genome sequence). The original ordering of F. vesca sequence scaffolds was performed without a physic…

Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport

2015

Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria × ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…

Vapour partition of aroma compounds in strawberry flavoured custard cream and effect of fat content

2008

International audience; Gas–matrix partition coefficients (k) of volatile compounds of a strawberry flavour added to a complex model system (custard dessert, COST action 921 recipe) were determined. The influence of fat content on the volatility of the strawberry aroma compounds was investigated using full fat milk- (FFM) and skimmed milk- (SM) custards. For the purpose of this study, the phase ratio variation (PRV) method was used because of its easy application for a mixture of volatiles without requiring any calibration. From the 15 aroma compounds present in the flavouring mixture, seven were volatile enough to be detected and concentrated enough to allow the calculation of k values. Ga…
