“…This report was confirmed in Portugal by Rei et al (1993) who detected CMV alone, as well as together with SLRSV. CMV in olive trees was also found in Spain (Bertolini et al, 1998), Turkey (Çağlayan et al, 2004), Syria (Alabdullah et al, 2005), Croatia (Bjelis et al, 2007), Tunisia (Martelli, 2011) and recently in California (Al Rwahnih et al, 2011).…”

“…OLV-2 was isolated by mechanical inoculation from symptomless olive trees in Apulia, Southern Italy (Savino et al, 1984). It has subsequently been identified in Lebanon (Fadel et al, 2005), Syria (Alabdullah et al, 2005), Croatia (Bjelis et al, 2007) and Tunisia (Martelli, 2011) from symptomless olive cultivars. The host range of OLV-2 was limited to olive trees until castor beans (Ricinus communis L.), showing yellowish vein netting and systemic mottling on leaves, were reported in Greece to be infected with this virus (Grieco et al, 2002).…”

“…The OLY syndrome, consisting of poor fruit set, bright yellow discoloration of the foliage, mottling, necrosis, extensive defoliation and dieback, has been associated to other viruses such as Olive vein yellowing associated virus (OVYaV) (Faggioli & Barba, 1995) and Olive yellow mottle and decline associated virus (OYMDaV) , but their presence on olive trees was very rare. On the other hand, OLYaV seems to be one of the most widespread olive viruses: in Italy it infects more than 60% of southern Italy olive cultivars (Faggioli et al, 2005) and it has also been reported in high percentages in Israel (Martelli, 2011), Egypt, USA (Saponari & Savino, 2003), Lebanon (Fadel et al, 2005), Spain (Martelli, 2011), Syria (Alabdullah et al, 2005), Albania (Luigi et al, 2009), Croatia (Bjelis et al, 2007, Tunisia (Martelli, 2011) and California (Al Rwahnih et al, 2011). A study on the rooting and grafting capacity of OLYaV-infected 'Carolea' and its respective healthy controls showed that the virus does not influence the rate of rooting of the cuttings and does not interfere with the grafting success rate; positive significant effects in grafting ability were observed on infected material only during a temperature stress, probably due to the reduced water need of infected shoots (Roschetti et al, 2009).…”

“…The virus was isolated for the first time from olive in cv. 'Corregiolo' in Italy (Savino et al, 1979) and later in Portugal (Henriques et al, 1992), Spain (Bertolini et al, 1998), Egypt, USA (Saponari & Savino, 2003), Turkey (Çağlayan et al, 2004), Lebanon (Fadel et al, 2005), Syria (Alabdullah et al, 2005), Croatia (Bjelis et al, 2007), Tunisia (Martelli, 2011) and Albania (Luigi et al, 2009). Small, pearshaped, puckered fruits with deformed kernels (bumpy fruits), narrow and twisted leaves, bushy growth and reduced crop were described in olive trees of cv.…”

We performed a survey on the yield, quality, and chemical characteristics of virgin olive oils from two olive varieties in Croatian Istria: Frantoio and Ascolana tenera, on Cherry leafroll virus‐infected and virus‐noninfected trees and on two harvest dates. Free acidity, peroxide value, specific spectrophotometric absorptions at 232 and 270 nm, fatty acid composition, total phenols, o‐diphenols, oil color, and pigments were determined. Infected olives had lower oil yield and maturity index versus healthy ones. Oils from infected fruits had significant lower value of K232 and K270 and very elevated total phenols content compared to those obtained from healthy olives. Infected Frantoio gave a lower content of o‐diphenols than the healthy ones, which is in contrast to infected Ascolana that had higher values. The aim of this study is to determine the chemical changes in virgin olive oils from healthy and infected trees related to virus influence. According to our knowledge, this is the first survey on the possible influence of viruses on olive fruits, oil yield, and virgin olive oil quality.Practical applications: There are only few papers which analyze the influence of viruses on crops (especially influence on wine quality) and their effects on yield or other agronomic parameters. This work evaluates for the first time the impact of Cherry leafroll virus on the quality of virgin olive oil obtained from Frantoio and A. tenera varieties in terms of basic parameters related to the hydrolitic and oxidative status, content in antioxidant compounds, and in pigments as well as in fatty acid composition.

Among the 15 virus species detected in olive trees, Olive leaf yellowing associated virus (OLYaV) is found with high incidence and frequency in Southern Italy in particular. Effects of OLYaV on virgin olive oil yield and quality of Leccino and Ottobratica cultivars in the Calabria region (Southern Italy) are analyzed. Oil yield, free acidity, number of peroxides, spectrophotometric indices, total content of chlorophylls and carotenoids, total phenol content, composition of the fatty acids, total tocopherols, and total sterols content are determined on oil obtained from olive fruits collected in healthy/virus‐free and OYLaV‐infected trees. Almost all analyzed oil parameters are not statistically different with some exceptions. Oils derived from ‘Ottobratica’ OLYaV‐infected plants have free acidity significantly lower than oil from healthy plants. K232 of oil from virus‐free ‘Leccino’ trees is significantly lower than oil from infected trees. Even though some quality parameter differences between healthy and OLYaV‐infected oils are found, it is important to highlight that all oils can be considered in extra virgin olive oil category, within the UE maximum limit acceptance range. Results suggest a no negative interference by OYLaV in oil yield and quality, except for K232 values, whereas surprisingly suggest a positive effect of virus infection on free acidity parameter. Practical Applications: Based on the evidence that OYLaV does not interfere negatively in oil yield and quality parameters, it seems appropriate that the European Union Council Directives (2014/96/EU, 2014/97/EU, 2014/98/EU) introduced in the last olive certification scheme only ArMV, CLRV, and SLRSV. The application of compulsory EU directive, in Italy as in other countries, will improve the facilities of olive plants commercialization, guaranteeing enough their sanitary status. The findings here reported support the suggestion that the Italian Ministry of Agriculture could be less restrictive in voluntary Italian regulation (D.M. 20/11/2006). Olive leaf yellowing associated virus (OLYaV) is found with high incidence and frequency especially in Southern Italy. Effects of OLYaV on virgin olive oil yield and quality of Leccino and Ottobratica cultivars in the Calabria region (Southern Italy) are analyzed, including free acidity, number of peroxides, spectrophotometric indexes, total content of chlorophylls, carotenoids and phenol, composition of the fatty acids, total tocopherols and total sterols.
