Studying these strategies allows explaining the survival of these species in such hostile and stressful conditions. In this study we compared some parameters (morphological, physiological and biochemical) of two Brassicaceae species Matthiola tricuspidata (L.) W.T.Aiton, Cakile maritima Scop., and two Fabaceae species Lotus creticus L. and Ononis variegata L., harvested from their natural environment in coastal dunes of Zemmouri El Bahri (Algeria), with the aim to understand their mechanisms of adaptation. The results revealed that C. maritime showed the highest relative water content, leaf area, leaf mass area, and succulence index. Based on the highest levels of total phenols, flavonoids and anthocyanins as well as high contents of photosynthetic pigments, M. tricuspidata can be classified as \"homoiochlorophyllous\" plant. The dry mass content varied considerably among species, with the highest values observed in L. creticus and the lowest in C. maritima. As both Fabaceae species L. creticus and O. variegata showed high chlorophylls, carotenoids, total phenols and flavonoids could also be classified as \"homoiochlorophyllous\" species. The relatively high levels of total phenols, total flavonoids, anthocyanins and carotenoids implies a biochemical adaptation that allows these plants to maintain necessary photosynthetic activity under a water deficiency condition.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":"0-0"},"PeriodicalIF":1.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.37427/botcro-2021-001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42735214","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}

It usually occurs in synanthopic habitats, represented mainly by urban and suburban roadsides, where it is quite sporadic. Based on current knowledge, it has been hitherto reported only in a few localities of the Mediterranean area, particularly in Morocco, Algeria, Tunisia, Libya, Spain, Portugal, Greece, Turkey, Syria and Crimea. Field observations and herbarium investigations have shown that this species is often mistaken for P. annua, mainly due to its morphological similarities, as well as for the same ecological needs, therefore its real geographical distribution has yet to be verified. Although the two species are both tetraploids (2n = 28), they clearly differ for numerous relevant features concerning the shape and size of ligules, inflorescence, spikelet, glumes, palea, lemma, anthers, lodicules and seed. In order to better clarify the relationships of P. maroccana with P. annua and the other annual species of this genus occurring in the Mediterranean, its carefull a morphological description and iconography is provided, as well as a comparative morphological table of all allied species and also their analytical key for easy identification.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":"80 1","pages":"0-0"},"PeriodicalIF":1.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42336300","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}

A new population with intermediate individuals that share morphological characteristics of both T. montanum and T. polium is found in Croatia (Bisko near Trilj), and most likely represent a hybridogenous taxon. The aim of this study is to compare morpho-anatomical and phytochemical characteristics of two parental species and their putative hybrid, as well as to determine the most important distinguishing characters between these three groups. In order to describe the variability and significance of morpho-anatomical and phytochemical differentiation of analysed groups several multivariate statistical analysis were conducted (PCA, CDA, DFA, UPGMA-clustering). All analyses confirm the separation of two species, T. polium and T. montanum, and reveal intermediate position of their putative hybrid. In this way, data of morphological and anatomical analysis together with data of the composition of the essential oils support the assumption of the hybridogenous origin of intermediate individuals. Based on descriptions and original indication of parental species of previously described hybrids T.  castrense Verg., T.  bogoutdinovae Melinkov and T.  rohlenae K.Malý, we found that intermediate specimens collected in Croatia perfectly match with T.  rohlenae, a hybridogenous taxon discovered by Rohlena in the vicinity of Kotor in Montenegro, and thus prove a presence of a new natural hybrid in the flora of Croatia.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":"0-0"},"PeriodicalIF":1.3,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.37427/botcro-2020-033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42904162","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}
