... Ilarvirus infection may result in a significant yield loss and a delay in fruit maturity [Pallás et al. 2012, Rubio et al. 2017. Additionally, other viruses are also detected in sour and sweet cherry: Little cherry virus 1 (LChV-1), Little cherry virus 2 (LChV-2) and Little cherry virus 3, (LChV-3) [Welsh and Cheney 1976, Isogai et al. 2004, Bajet et al. 2008, Ludvíková and Suchá 2011, Rao et al. 2011, Lu et al. 2015, Zong et al. 2015, Ruiz-García et al. 2016, Šafářová et al. 2022, Cherry virus A (CVA) [Jelkmann 1995, Isogai et al. 2004, Rao et al. 2009, Zong et al. 2015, Kinoti et al. 2016, Wang et al. 2018, Simkovich et al. 2021, Cherry green ring mottle virus (CGRMV) and Cherry necrotic rusty mottle virus (CNRMV) [Wadley and Nyland 1976, Desvignes et al. 1999, Zhang et al. 2000, Gentit et al. 2002, Isogai et al. 2004, Sabanadzovic et al. 2005, Mandic et al. 2007, Fiore and Zamorano 2013, Zhou et al. 2013, Cho et al. 2014, Zong et al. 2015, Cherry mottle leaf virus (CMLV) [James and Mukerji 1993], and Cherry leaf roll virus (CLRV) [Cropley 1961]. ...
... These results correspond with those that have been previously obtained in Poland and that show a low rate of infection with lesser-known viruses, such as CVA and LChV-1 [ Komorowska and Cieślińska 2004], CGRMV [Komorowska and Cieślińska 2005], LChV-2 [ Komorowska and Cieślińska 2008], LChV-1, and CGRMV [Cieślińska and Morgaś 2010]. On the other hand, a high incidence of the lesser known viruses has been reported in other countries: Serbia [Mandic et al. 2007], China [Rao et al. 2009, Zhou et al. 2013, Lu et al. 2015, Wang et al. 2018, Chile [Fiore and Zamorano 2013], Korea [Cho et al. 2014], Japan [Isogai et al. 2004, Zong et al. 2015, the USA (California) [Sabanadzovic et al. 2005], Australia [Kinoti et al. 2016], Canada and the USA [Bajet et al. 2008, Simkovich et al. 2021, and Spain [Ludvíková andSuchá 2011, Ruiz-García et al. 2016]. ...
A survey was carried out on a commercial sour cherry fruit orchard located in Lublin province in Poland to determine the influence of viruses on the fruit quality of sour cherry cv. Łutówka. Leaf samples from trees of sour cherry cv. Łutówka were tested for Prunus necrotic ringspot virus (PNRSV), Prune dwarf virus (PDV), Little cherry virus 1 (LChV-1), Little cherry virus 2 (LChV-2), Cherry virus A (CVA), Cherry green ring mottle virus (CGRMV), Cherry necrotic rusty mottle virus (CNRMV), Cherry rasp leaf virus (CRLV) and Cherry mottle leaf virus (CMLV) using the RT-PCR technique. The results indicated that PNRSV and PNRSV+CVA infected the samples. PDV, LChV-1, LChV-2, CGRMV, CNRMV, CRLV, and CMLV were not detected in any of the tested sour cherry trees. The effect of virus infection on the chemical composition of sour cherry fruits was investigated. The anthocyanin, total phenolic and vitamin C contents, and antioxidant activity were evaluated. The total phenolic compound, vitamin C contents, and antioxidant activity were significantly higher in PNRSV- and PNRSV+CVA-infected than in virus-free sour cherry fruits. The total anthocyanin content in PNRSV- or PNRSV+CVA-infected fruits was lower than in control trees. To our knowledge, this is the first report in the world about the effect of PNRSV or PNRSV+CVA infection on the anthocyanin compounds, total polyphenolic compounds, vitamin C contents, and the antioxidant activity of sour cherry fruits.
