Seed morphometry and fatty acid profile in oilseed and non-oilseed sunflower cultivars
Sunflowers are a globally cultivated crop, valued for their oil-rich seeds and diverse nutrient content. 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.
期刊介绍：
Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology).
In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
