Plums, the most commonly consumed fruits from Romania, are fruits rich in bioactive compounds, such as antioxidants. This research work was carried out to investigate the antioxidant potential of twelve plum cultivars, fresh and stored during 10days at 4°C by using different methods (DPPH, ORAC and erythrocyte resistance to haemolysis). The contents of total phenolic compounds and total anthocyanins were also determined by specific spectrometric methods. Significant differences between fresh and stored plum cultivars (p<0.05) were found. Storage at 4°C resulted in an increase in antioxidant potential and anthocyanins content of the autumn plum varieties. Autumn plum varieties also showed a higher antioxidant capacity than summer varieties, as assessed by the ORAC and the haemolysis resistance assays. Our results suggest that, even after storage, plums could be a good source of antioxidants, which may provide health-promoting effects for humans.

Article Synopsis
- The study analyzed the physiochemical characteristics of 11 plum varieties from Southern China, focusing on aspects like fruit weight, juice rate, color, moisture, total soluble solids, and various nutrient contents.
- Results indicated significant variations in nutrient levels among cultivars, with 'Da Pao' having the highest total polyphenols and antioxidant activity, while 'San Hua' excelled in total anthocyanins.
- Principal component analysis distinguished the cultivars based on these characteristics, offering valuable insights for consumers and potential processing applications.

Unlabelled: Understanding the genetic diversity of crops is of fundamental importance for the efficient use and improvement of germplasm resources. Different molecular genotyping systems have been implemented for population structure and phylogenetic relationships analyses, among which, microsatellites (SSRs) and single nucleotide polymorphisms (SNPs) markers have been the most widely used. This study reports the efficacy of SNPs detected via double-digest restriction-site-associated DNA sequencing (ddRADseq) and SSRs analyzed via capillary electrophoresis (CE) and high-resolution melting (HRM) in tomato.

Domestic storage conditions can have a significant impact on the composition of phytochemicals and sugars in stone fruits. This study aimed to evaluate the effect of two domestic storage temperatures (4 and 23 °C) on the physicochemical properties, phytochemical composition, and sugars of 'Rubycot' (RC) plumcot, a novel stone fruit variety, and 'Queen Garnet' (QG) plum. Initially, RC had a lower total anthocyanin concentration (TAC) than QG, but TAC in RC increased significantly ( < 0.

Article Synopsis
- - Apples and plums both belong to the Rosaceae family and contain phytochemicals, but their seeds are particularly high in cyanogenic glycosides that can produce toxic hydrogen cyanide when damaged.
- - The review examines how the distribution of these cyanogenic compounds varies in different parts of the fruits, how it changes during development, and the environmental factors that affect their production, highlighting significant gaps in current research.
- - Processing techniques, such as seed separation and microwave heating, can help reduce cyanide levels in these fruits, and there's a notable concern regarding the storage of waste-derived products, like plum stones, as HCN levels may increase over time.

The flavor profiles of cherries cultivated in greenhouse and those grown in open fields show significant variations, however, the underlying flavor-contributing factors remain unidentified. Hence, a joint investigation with widely targeted metabolomics analysis, volatile fingerprint analysis, and descriptive sensory analysis for the Russia 8 and Tieton cherry cultivars was conducted using UPLC-MS/MS and GC × GC-TOFMS to clarify the flavor differences of open-air and greenhouse-grown cherries. The study found that open-air cultivation could lead to the accumulation of non-volatile flavor substances and prompted appearance of higher acidity, astringency, plum-like flavor, and fresh herb notes; most of differential metabolites were significantly positively correlated with astringency, plum-like flavor and bitterness.
