This study delved into the morphological traits and fatty acid profiles of 14 oilseed and non-oilseed sunflower cultivars from Iran. We assessed 10 qualitative and quantitative seed characteristics and analyzed the seed oil using gas chromatography after n-hexane extraction. Statistical analyses were conducted using SPSS and PAST software. The study revealed significant variations in seed morphological characteristics among the cultivars, with certain traits exhibiting strong correlations. Non-oilseed cultivars displayed larger dimensions and weight compared to oilseed cultivars. The seed oils were primarily composed of unsaturated fatty acids (UFAs), with linoleic (C18:2(9c, 12c)) and oleic (C18:1(9c)) acids being the dominant polyunsaturated and monounsaturated fatty acids, respectively, in all cultivars except Diamantis, which showed an inverse pattern. The total saturated fatty acids (SFAs) content was below 18%, with palmitic acid (C16:0) as the primary SFA and stearic acid (C18:0) as the secondary compound in all cultivars, except for Ghassem, which exhibited a reverse pattern. Notable correlations between various fatty acids and morphological traits highlighted the influence of phenotype on oil chemical composition. Using the UPGMA tree, the cultivars were categorized into five chemotype groups. The PCA-biplot revealed distinct chemical compound characteristics for some groups, aligning with an earlier classification of sunflower cultivars based on C18:1(9c) content. Overall, the findings of this study provide valuable insights into the seed morphological, chemical characteristics and significant correlations between quantitative traits and fatty acid composition. Moreover, highlight their potentials for targeted breeding programs to develop sunflower cultivars with desirable traits for both the food and oil industries. However, these results suggest that these oils possess varying potential for culinary or industrial applications, emphasizing the importance of considering fatty acid composition when selecting oil for specific purposes.</p></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139935459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mountain tea (<em>Stachys lavandulifolia</em> Vahl) is a perennial plant in the Lamiaceae family, having prominent medicinal properties due to its unique chemical composition. The current research evaluated effective traits that shape the content of essential oil (EO) and phytochemical compounds in <em>S. lavandulifolia</em> populations (P). Samples were collected from 20 different habitats located in the west and northwest of Iran. The results indicated that the Heris (P3) and Sarab (P7) populations exhibited high levels of EOs and phytochemical properties. In the studied areas, principal component and cluster analyses considered environmental factors like climate and soil, thus revealing significant findings. Soil characteristics, including organic matter content, total nitrogen (N), potassium (K), and soil phosphorus (P) content, were identified as the most influential factors, with average annual rainfall following closely. The highest average annual temperatures largely contributed to distinguishing the areas, thus categorizing the habitats into three distinct groups. EO from 20 populations analyzed using GC/MS showed 41 compounds, the most important of which were α-pinene (1.21–33.29 %), α-bisabolol (0.71–53.05 %), and spathulenol (2.8–18.8 %), germacrene-D (1.13–12.18 %), β-phellandrene (0.09–16.72 %), myrcene (1.01–13.34 %), phytol (1.19–10.14 %), and viridiflorol (0.93–6.19 %). Grouping the <em>S. lavandulifolia</em> populations based on their main compounds in the EO divided them into two distinct habitats. The first habitat had eleven <em>S</em>. <em>lavandulifolia</em> populations, whereas the second had nine. Comparison of mean values among habitats showed that the first habitat was superior to the second, regarding sesquiterpene chemical compounds such as spathulenol, viridiflorol, α-muurolol, α-cadinol, and valeranone. The second habitat was more suitable than the first because of higher amounts of monoterpene chemical compounds, such as α-pinene, myrcene, and β-phellandrene. Overall, in this study, Heris (P3), Azarshahr (P4), and Sarab (P7) populations were favorable because of their EO yield and compounds.
