For instance, the link between parental tree traits, such as age and size, and acorn characteristics has seldom been addressed; yet it could be decisive for streamlining acorn selection. In this study, we employed Structural Equation Models (SEM) to examine the relationship between parental tree Diameter at Breast Height (DBH) and acorn traits determinant for seed germination in <em>Quercus</em> species worldwide. Specifically, we measured acorn dry mass (ADM), seed moisture (SM), and pericarp thickness (PT) in a <em>Q. ilex</em> population in central-western Spain. Our results indicate a significant positive influence of parental tree DBH on ADM, with larger acorns associated with higher germination percentages. Similarly, SM positively influenced germination, though it was influenced by acorn size through two contrasting pathways. PT, on the other hand, negatively impacted germination and was also negatively affected by ADM. These findings suggest that acorn selection should prioritize large/old trees to maximize germination via increased ADM. Further research, nonetheless, is needed to progress in the relationships between parental tree traits and acorn characteristics in this and other similar contexts in which large-scale plans for <em>Q. ilex</em> regeneration would be planned.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"583 ","pages":"Article 122587"},"PeriodicalIF":3.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465166","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}
