Nevertheless, einkorn oil is little studied. Given a renewed interest in this crop, the purpose of the study was to investigate the lipid contents and fatty acid composition of oil from diploid wheat grain. Oil was extracted from dried whole wheat kernels by Soxhlet procedure. Fatty acid composition was determined by gas chromatography. The oil yield from the diploid wheat grain varied from 2.830.27% dry basis in Triticum monococcum var. sofianum Stranski to 4.460.49% in Triticum sinskayae A.Filat. et Kurk. Six major fatty acids were detected in all the wheat species under investigation. They are ranked in order of decreasing levels as follows: linoleic > oleic > palmitic > linolenic > stearic > palmitoleic. Ploidy doubling brought no significant alterations in fatty acid composition of T. monococcum grain. T. monococcum var. sofianum had the most beneficial unsaturated/saturated ratio (5.3) and the lowest the ratio of omega-6/omega-3 (9:1). Triticum boeoticum Boiss. (wild progenitor of einkorn) was inferior to domestic diploid wheat in terms of unsaturated fatty acid amounts, despite the very high total oil content (4.190.48%). As wheat oil is used in the cosmetics industry and given the surprisingly high oil yields from the diploid wheat grain, the collection accessions are worth considering through the lens of this trend in wheat products. However, none of the studied accessions can be recommended as breakthrough advantageous because of the ratios of omega-6/omega-3 of not lower than 9:1.","PeriodicalId":37521,"journal":{"name":"Contributii Botanice","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49609885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the last decade this territory has been subjected to increasing anthropogenic pressures, and specific concerns on biodiversity have been raised after the construction of a wind farm in 2011. Starting from a concern expressed by a scientist, our study aims to provide current data on plant species with conservation value and to assess the conservation status of orchid-rich grasslands around wind turbines after ten years of wind farm operation. During the operation period we identified 19 plant taxa with conservation value, eight of which which are orchid species. Four of them are new reports for this territory: Gymnadenia conopsea, Neotinea ustulata, Neottia nidus-avis and Orchis simia, as well other rare taxa such as Cirsium grecescui, Lathyrus sphaericus, Linum hologynum and Rumex thyrsiflorus, are mentioned for the first time. The orchid-rich grasslands in the wind farm area correspond to the Natura 2000 habitat 6210* whose structure and floristic composition are within the acceptable limits of Favourable conservation status. The conservation status of plant species is directly dependent on the quality of their habitat, as well as the variety of pressure and threat factors in the area.","PeriodicalId":37521,"journal":{"name":"Contributii Botanice","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69190366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present data of biodiversity research in the Republic of Mordovia (European Russia). The obtained results are reflected in six vascular plant found for the first time in the studied region. Of them, four alien taxa (Philadelphus coronarius, Rosa x majorugosa, Spiraea japonica, Syringa josikaea) are known only in the Mordovia State Nature Reserve now. This underlines the need paying our attention to alien plants that escape into the wild (naturalize) in the least disturbed ecosystems of this Protected Area. The Urtica galeopsiifolia distribution needs to be clarified in more details because of its similarity to the widely known Urtica dioica. Thus, a majority of the species under discussion are alien plants considered as cultivated plants escaping in the wild. Taking into account the newly revealed species, the vascular plant flora of the Republic of Mordovia currently includes 1,472 species. In this study, we propose the continuing the study of man-made habitats in terms of accidentally or intentionally introduced alien species, as well as the searching of hidden taxa, such as Urtica galeopsiifolia found in this study.","PeriodicalId":37521,"journal":{"name":"Contributii Botanice","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69191332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Branch canker and dieback of citrus is an ongoing problem for citrus growers located in these areas and has imposed irreparable damage to the citrus production in this region in recent years. Disease symptoms consisted of the blight of vigorously growing shoots and dieback of the branches and rootstock trunks. This study aimed to characterize the citrus dieback pathogen morphologically and phylogenetically, and the species Neodidymelliopsis iranensis Soleimani & Goudarzi, sp. nov., is described and illustrated here. Isolates were derived from collected citrus samples with dieback symptoms. After preparing pure cultures from single spores on oatmeal agar and malt agar, the morphological features of the species were described and their pathogenicity was confirmed on lime (Citrus aurantifolia). Morphologically N. iranensis is easily separated from the other species of Neodidymelliopsis by the size of pycnidia, conidia septation, and NaOH test results. The morphological differences between our isolates and the other known species of Neodidymelliopsis were strongly supported by a multi-locus phylogenetic analysis based on the ITS region, and LSU, RPB2, and TUB2 genes. In the reconstructed phylogenetic tree, N. iranensis formed a well-supported clade with other Neodiddymelliopsis species in the Didymellaceae family, but was separated from all other Neodiddymelliopsis species. The distinct phylogenetic position is supported by differences in morphological features. Consequently, the specificity of the morphological and phylogenetical features of the collected isolates has convinced us to describe Neodidymelliopsis iranensis as a new species.","PeriodicalId":37521,"journal":{"name":"Contributii Botanice","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47163799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
