Despite the social and economic importance of olive cultivation, a comprehensive evaluation of olive quality remains lacking to date. Thus, this study aimed to compare and characterize 20 quality-related indices across 20 olive cultivars grown in China by using Pearson correlation, principal component, and hierarchical clustering analyses. All the tested indices exhibited significant variations among the 20 olive cultivars. Five principal component factors were extracted to establish a comprehensive quality evaluation model represented by <em>Y</em> = 0.398Y₁+0.286Y₂+0.140Y₃+0.105Y₄+0.071Y₅. Based on their comprehensive scores, the 20 olive cultivars were categorized into four distinct groups. The cultivars Cornicabra, Picholine Languedoc, Koroneiki, Picual, Yuntai14, and Coratina were classified within the excellent-quality group. The core quality parameters for olives in Longnan City included moisture content (MC), peroxide value (PV), oil content (OC), ratio of monounsaturated and polyunsaturated fatty acids (MUFA/PUFA), ratio of oleic and linoleic acids (C18:1/C18:2), total polyphenol content (TPC), and oxidative stability (OS). This study may serve as a basis for evaluating olive quality and advancing standardized quality classification. It also promotes high-value development and utilization within the olive industry, particularly for the development of functional foods and innovation in lipid-based products.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"351 ","pages":"Article 114387"},"PeriodicalIF":4.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnesium (Mg), a crucial component of chlorophyll in light energy utilization, has a largely unexplored role in mitigating sunburn in citrus fruits. This study investigated the effects of Mg treatments on sunburn incidence, damage severity, photosystem II (PSII) integrity, and oxidative stress in citrus peel, using Satsuma mandarins and navel orange in both field trials and simulated sunburn conditions. Field trial indicated that Mg applications at 150 g MgO tree⁻¹ for Satsuma mandarins and 200 g MgO tree⁻¹ for navel oranges reduced sunburn incidence by 6.6% and 12.4%, respectively, compared to untreated trees. Fruits from these treatments and a control group (0 g MgO tree⁻¹) were collected for simulated sunburn experiments. Mg fertilization (150 g MgO tree⁻¹) significantly increased chlorophyll content in the flavedo by 36.6% in Satsuma mandarins and 22.8% in navel oranges compared to untreated fruits. Both field and controlled experiments consistently showed that Mg supplementation significantly decreased hydrogen peroxide (H₂O₂) and malondialdehyde (MDA) concentrations while enhancing antioxidant enzyme activities, including superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT). Additionally, Mg treatments improved photosynthetic performance, regulated energy dissipation, and enhanced light energy utilization, contributing to greater PSII resilience under high light stress. Transcriptomic analysis revealed that Mg applications upregulated genes associated with cellular respiration, H₂O₂ metabolism, and lipid oxidation pathways in Satsuma mandarin flavedo. These findings highlight the role of Mg in strengthening the antioxidant enzymes and improving photosynthetic efficiency, thereby mitigating oxidative damage and lipid peroxidation under sunburn conditions. The results provide valuable insights into the potential of Mg fertilization as a strategy to reduce sunburn related damage and enhance citrus fruit quality in regions prone to high temperature and intense sunlight.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"351 ","pages":"Article 114408"},"PeriodicalIF":4.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, we investigated the relationship between differences in developmental rates among fruit portions and fruit morphology in persimmon (<em>Diospyros kaki</em>), a species known for its high morphological diversity. Starting two weeks after blooming (WAB), surface landmarks were routinely drawn along the calyx-apex line on fruits of four persimmon cultivars with diverse shapes, and the landmark displacement was quantified every two weeks using 3D phenotyping. Consistent with previous studies, all cultivars exhibited active development in the regions near the calyx, with the greatest difference in growth rates between the calyx and apex occurring at 6–8 WAB. However, the extent of these spatial differences varied among cultivars. In elongated fruits, a gradual growth gradient was observed from the calyx toward the apex, with relatively high growth rates even near the apex. In contrast, in flattened fruits, growth was highly concentrated near the calyx, while development in other regions remained minimal.

Plants were grown on their own roots or on the PRO5 rootstock. Summer cultivation was on rockwool, and the bushes were formed using the bending method. Based on the results, the flower yield did not depend on the propagation method, although bushes growing on their own roots started flowering earlier than those on the PRO5 rootstock. The method of propagation did not affect shoot length, however, cut shoots grown on PRO5 were heavier, especially in May, approximately 30 % than shoots cut from bushes grown on the own roots. Neither the propagation method affects the vase life, which was mainly related to the harvest date, longer in May than in July. Compared to plants growing on their own roots, those on PRO5 were better nourished: they had higher sugar contents (total sugars, reducing sugars and starch) in roots respectively, by 28, 24 and 34 % and flowers (total sugars by 29 and reducing sugars by 19 %), higher by 31 % soluble protein level in flowers and a higher by 27 % chlorophyll content in the leaves. Nor it significantly affected anatomical changes in shoots and petals. The latter were associated with the flower opening process. As the flower development progressed the intense growth of the mesophyll cells and petal epidermis was observed, as well as changes in their shape. During flower bloom, accumulation of starch in the stems was observed, regardless of how the bushes were grown.
