Dietary supplementation is an effective approach to improve human selenium status. However, research on selenium-enriched cultivation techniques for kiwifruit and their effects on fruit quality remains limited. In this study, <em>Actinidia chinensis</em> ‘Jinfeng’ plants were foliar-sprayed with different types and concentrations of selenium fertilizers at various fruit developmental stages to investigate their effects on fruit selenium accumulation and quality and to identify the optimal selenium-enrichment treatment. Subsequently, the accumulation and distribution patterns of selenium, as well as its impacts on fruit developmental quality and storage characteristics, were examined. The results showed that the optimal selenium-enrichment strategies for ‘Jinfeng’ kiwifruit were foliar application of 50 mg/L nano-selenium at the young fruit stage or 75 mg/L selenium-yeast at the fruit expansion stage. Selenium treatment significantly increased fruit selenium content, improved single-fruit weight, and enhanced fruit quality. It also promoted the uptake of mineral elements in leaves and pulp but had no significant effect on flesh cadmium content. During ambient storage, selenium treatment did not significantly affect dry matter or soluble solids content; however, nano-selenium was more effective than selenium yeast in reducing decay rate and weight loss, thereby extending shelf life. These findings provide a theoretical basis and technical support for elucidating the effects of selenium on ‘Jinfeng’ kiwifruit quality, exploring scientific approaches for selenium biofortification in kiwifruit, and promoting efficient production of selenium-enriched kiwifruit.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"359 ","pages":"Article 114790"},"PeriodicalIF":4.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147551236","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}

Results showed that altitude significantly impacted meteorological variables, tree water needs and water status, phenology, and fruit growth. Trees at 1030 m, under cooler, more humid conditions, exhibited a longer fruit development and less negative values of stem and trunk water potential (>-1.3 MPa), resulting in larger fruit (50% of the cherries were larger than 28 mm) compared to those at 480 m (hotter and drier environment), where fruit grew faster and high evaporative demand led to water stress (water potential below -2.0 MPa) and smaller fruit (50% of the cherries had diameters between 24 and 26 mm). RDI maintained better tree water status and enhanced fruit size, particularly at lower altitudes. Soil water content and stomatal conductance varied by altitude and irrigation treatment, with RDI helping to mitigate water deficit stress in both situations.
