“…The titratable acidity ranged between 0.8% and 2.7% (Zhang et al, 2015). Similar observations were found in other studies (Cantin et al, 2010;Kwon et al, 2015;Drogoudi et al, 2016). Although our results are in accordance with other studies, some variations were thought to have been due to the harvest time and differences among the genotypes.…”

IntroductionGoji berry is the common name of the species Lycium barbarum, Lycium chinense, and Lycium ruthenicum, belonging to the genus Lycium of the family Solanaceae, and it is known to occur more often in tropical and subtropical regions of the world (Levin and Miller, 2005). The plant is common in Mongolia, the Himalayas, western China, and Tibet (Bucheli et al., 2011), where it occurs in arid, semiarid, and slightly semisaline regions (Fukuda et al., 2001).Worldwide, goji berry is also known as wolfberry. While Lycium ruthenicum has small black berries, Lycium barbarum has various colored berries, ranging from orange to dark red. These 2 species are cultivated commercially, with studies having been conducted more often on Lycium barbarum. Goji berry is a bush-type perennial plant, which is highly tolerant to climatic and environmental conditions, that is able to uptake necessary nutrients and water from the soil due to its advanced root system. Although Lycium barbarum and Lycium ruthenicum have similar morphological properties, specific morphological properties are obviously characteristic in distinguishing these 2 species (Wang et al., 2015).In Lycium barbarum, the leaves are long and elliptical, pedicel is 1-2 cm long, calyx usually has 2 lobes that are 2-or 3-ribbed at the end, corolla tube is 8-10 mm long and longer than the lobes, and the berries are red or orange, yellow, rectangular, and oval. There are usually between 4 and 20 brown or yellow seeds per berry. Lycium ruthenicum is bushy like Lycium barbarum and it is rather branched. Leaves are fleshy, linear, or slightly cylindrical. Calyx is dispersed with 2-4 lobes, pedicel is 5-10 mm long, berries are spherical purple and black, sometimes its head or edge is notched, and the seeds are especially brown (Mi et al., 2015).Goji berry plants are highly tolerant to adverse environmental conditions and grow at different altitudes ranging from 700 to 2700 m. In China, the plant is very popular and it has been consumed as a food for centuries due to its many benefits for health and its effect on longevity (Gündüz et al., 2015).The berries, harvested from the beginning of summer to the end of autumn, are consumed either fresh or dried (Amagase and Farnsworth, 2011; Gundogdu et al., 2018). More recently, studies on the goji berries of the species Lycium have focused on potential health-benefitting Abstract: Goji berry is a lesser-known fruit species and its berries have been used in traditional medicine for centuries as remedies to treat eye, liver, and kidney ailments, as well as for the prevention of cancer symptoms due to its high phytochemical content. This study aimed to investigate changes in the pomological, biochemical, and phytochemical properties of the berries of 4 goji berry genotypes harvested during 4 months (June, July, August, and September) of the same year. The results indicated that the highest berry dimensions (height and width) and soluble solid content were obtained from Genotype 2, harvested in June. The vitamin C, total phenolic, an...

“…Regarding flesh firmness, it should be mentioned that the negative correlation with pathological traits may be attributable, at least in part, to the width and fleshiness of the pulp due to the sporadic nature of fruit‐bearing within the T1E population. Taken together, these results indicate that the disease was easily developed and spread in fruit with softer pulp and/or lower malic acid levels, both characteristic of mature fruit, the stage most susceptible to infection as reported by various authors who have focused on the understanding of how susceptibility to brown rot changes with ripening …”

Exploring sources of resistance to brown rot in an interspecific almond × peach population

BACKGROUND Monilinia spp. are responsible for brown rot, one of the most significant stone fruit diseases. Planting resistant cultivars seems a promising alternative, although most commercial cultivars are susceptible to brown rot. The aim of this study was to explore resistance to Monilinia fructicola over two seasons in a backcross one interspecific population between almond ‘Texas’ and peach ‘Earlygold’ (named T1E). RESULTS ‘Texas’ almond was resistant to brown rot inoculation, whereas peach was highly susceptible. Phenotypic data from the T1E population indicated wide differences in response to M. fructicola. Additionally, several non‐wounded individuals exhibited resistance to brown rot. Quantitative trait loci (QTLs) were identified in several linkage groups, but only two proximal QTLs in G4 were detected over both seasons and accounted for 11.3–16.2% of the phenotypic variation. CONCLUSION Analysis of the progeny allowed the identification of resistant genotypes that could serve as a source of resistance in peach breeding programs. The finding of loci associated with brown rot resistance would shed light on implementing a strategy based on marker‐assisted selection (MAS) for introgression of this trait into elite peach materials. New peach cultivars resistant to brown rot may contribute to the implementation of more sustainable crop protection strategies. © 2019 Society of Chemical Industry

“…The results were expressed in M/ml in fresh weight. Total polyphenol content was quantified using the Folin-Ciocalteu reagent method after Wang (2017) and Drogoudi (2016) with some modification. A hydro-alcoholic extract (25 µl) was mixed with 1.975 µl distilled H 2 O, add 125 µl Folin -Ciocalteu and 375 µl of Na 2 CO 3 was added to the mixture.…”

The aims of this work were to determine which storage conditions can preserve the quince quality (Cydonia oblonga Miller, Rosaceae family), stored in three different rooms with controlled atmosphere (CA). Due to their reported high polyphenolic content in the fruit, three varieties of quinces, like Ekmek, Bereczhi and Tinella were stored and monitored for twelve months. During storage period, the following quality parameters were monitored: dry matter content (D.M.%), titratable acidity (TA), soluble solids (°Brix), firmness, antioxidant capacity and also content in total flavonoids and total polyphenols. After twelve months of storage, observations showed that quince from Tinella variety presented better quality parameters compared to quinces from Ekmek and Bereczhi varieties. As expected, keeping quinces in the presence of CO2content, respectively 2% and 5%, presented better physical and biochemical quality compared with those stored without CO2 (control).
