“…It is known that anthocyanins are associated with an increase in resistance plants for cooling and freezing, the integumentary tissues of some winter-hardy plants contain high concentrations of anthocyanins. In addition to this function, anthocyanins and chalcones are components of the antioxidant defense, protecting the body from oxidative stress [14]. In our studies in November, the content of anthocyanins in the bark of the studied apple varieties was 4.5-7.3 c.u.…”

“…It has been shown that the synthesis of proteins, dehydrins, increases during hardening and, possibly, they prevent the formation of ice in plant cells [13]. The accumulation of secondary metabolites, in particular anthocyanins, in the cover tissues of shoots of various woody plants correlates with resistance to low negative temperatures [14]. Thus, the above parameters can be considered as criteria for the adaptation assessment of the apple tree to the stress factors of the winter period.…”

The purpose of these studies is to assess the adaptive resistance of the apple tree to winter stresses in terms of physiological and biochemical parameters, to identify the most resistant varieties for cultivation in the Krasnodar region. Objects of research are apple varieties of various origins: Orfey, Idared, Ligol, Prikubanskoe. It was found that the cryoprotective function of water-soluble sugars was maximally manifested in the varieties Orfey and Ligol, their content increased by 2.56 and 2.7 times, respectively. Soluble proteins made the greatest contribution to the formation of a protective response in Orfey and Prikubanskoye varieties in January, their content increased 1.8 and 1.9 times, respectively, compared to December. The protective function of anthocyanins was maximally manifested in December in the Orfey variety, in the bark of which their content increased by 5.6 times. Physiological and biochemical adaptation of apple varieties to low negative temperatures of the winter period is achieved by increasing the content of water-soluble sugars, proteins in anthocyanins in the bark and buds. According to the obtained data, the apple varieties Orfey and Prikubanskoye showed themselves to be more adaptive in comparison with other studied varieties and are recommended for cultivation in the Krasnodar region.

“…Extensive studies have shown that the existence of phenolics in food, especially in fruit, is important. The presence of phenolics in human diet is beneficial as it prevents degenerative diseases owing to its free radical scavenging activity (Holderbaum, Kon, & Guerra, ). Figure b shows that the total phenolic content in the apple slices differed when the slices were dried using five different methods.…”

In this study, a novel two-step drying method using a combination of air jet impingement (AJID) and microwave vacuum drying (MVD) was proposed for drying apple slices.Chemical (vitamin C, total phenolic, soluble solid content, and titratable acid) and physical properties (energy consumption, color, and rehydration ratio) were assessed and compared with those of apples dried solely by hot air drying, freeze-drying, AJID, and MVD, respectively. Results showed that the optimal conditions for drying apple slices using air jet impingement were 65 C drying temperature, 2.3 m/s air velocity, and 6 mm thickness; the optimal combination was used first for 60 min AJID, followed by 40 min MVD, with final moisture content of 12.65 ± 0.63%. Based on the quality of apple slices and the energy consumption of the drying equipment, combined AJID-MVD appears to be a promising method for drying apple slices.

“…Alternatively, the low variation at these two structural genes may be due to selection on the cis ‐regulatory region, a potential target of MdMYB1 binding (Tian et al, 2017), rather than on the coding sequence that would impact enzyme function. The MdPPO gene encodes an enzyme with a major role in fruit browning, an easily observable phenotype and one that is the subject of intensive research in modern fruit breeding programs (Di Guardo et al, 2013; Holderbaum et al, 2014; Li et al, 2014), including the development of non‐browning apples through genetic modification to silence the MdPPO gene (Murata et al, 2001). While the reduced diversity at the MdPPO gene in our study suggests that this trait may also have been the subject of selection during apple domestication, there is still substantial variation in browning across apple cultivars (Holderbaum et al, 2014).…”

PREMISE During plant domestication, traits can be subject to a variety of types of selection, ranging from strong directional selection for traits such as seed or fruit size to diversifying selection for traits like color or flavor. These types of selection interact with other evolutionary processes including genetic bottlenecks and interspecific gene flow to generate different levels of genetic diversity across the genome and at target genes in domesticated lineages, but little is known about the impacts of these processes in perennial fruit crops. METHODS We used sequence capture by hybridization to examine patterns of diversity at a suite of candidate domestication and anonymous background genes in domesticated apple (Malus ×domestica) in comparison to its wild relatives Malus sieversii and Malus orientalis. RESULTS We found no change in average diversity at these candidate domestication genes across the three species. However, a subset of the genes did exhibit patterns of very high or very low diversity in M. ×domestica compared to its progenitor, M. sieversii. Of the genes with characterized function, the low‐diversity genes mainly contributed to fruit quality traits like color and flavor, predicted to be under conscious, directional selection relatively late in the domestication process, while the high‐diversity genes included a variety of functions. CONCLUSIONS Overall, these results are consistent with predictions based on the likely timing and nature of selection during domestication and open new avenues for understanding genes with high diversity in a perennial crop compared to its wild relatives.
