The alien status and distribution of C. moschata together with its relatives C. ficifolia C. pepo and C. maxima are reviewed for the Spanish references. This study outlines the first record of a naturalized population of C. moschata in Spain, well supported by the stability of the population along the years and ecological conditions. Finally, the detailed ecological data indicate that the agricultural activities together with riparian habitats, respectively, are starting points and corridors for seed dispersal for the process of invasion of alien plants in the southeastern Iberian Peninsula.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49661311","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}

The effects of EB on the growth, free, semi-bound, and bound boron (B) concentrations, and macromolecules of the Solanum lycopersicum L. cultivar Castle Rock, were investigated in this study. Seedlings were exposed to four levels of EB using boric acid. The results manifested that EB inhibited tomato growth, total water content, and photosynthetic pigments. EB harmed the membrane stability, as seen by increased potassium (K) leakage, UV absorbance metabolites, and electrolyte conductivity (EC) in leaf disc solution. EB raised concentrations of free, semi-bound, and bound forms of B in seedlings. Fourier transform infrared spectroscopy (FTIR) data revealed that EB induced uneven wax deposition, altered the shape of cell walls, and lowered cellulose synthesis in seedlings. EB affected the amide I and amide II indicating damage to the protein pools. These results provide new insights into understanding the specific effects of EB on the functional groups of different macromolecules of tomato seedlings.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42144707","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}

The survey included 507 plant taxa, belonging to 95 plant families. The results show that most plant species depend on insect pollination (73.6%), followed by self-pollination (30%), wind (25%) and water pollination (0.6%). For some plant species there are one, two or more modes of pollination; the largest group consists of pure insect pollination (43%), followed by both insect and self-pollination (27%), pure wind pollination (22%), insect and wind pollination (2.6%), and so on. Overall, 54% of plant species useful to European honey bees were found, of which 51% provide pollen and 47% nectar. These results suggest that A. mellifera could be a potential pollinator for about half of the flora. Analysis shows significant differences in pollination patterns among habitat types and that most entomophilous plant taxa are found in grassland, forest and ruderal sites, indicating that these habitats are most important for pollinators. Other characteristics of plant species, such as flowering time, plant family, life form and origin, were also analysed to determine a possible relationship with pollination.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44511814","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}

Despite higher levels of lipid peroxidation, lower membrane stability index (MSI), decreased pigment content and phenolic compounds, and reduced activity of antioxidant enzymes observed under salinity, seedling growth indices, including plant height and biomass, increased significantly, and some protective and antioxidant molecules such as proline and flavonoids accumulated. Soluble protein level increased at the low salt concentration (200 mM) but decreased at other doses. Exogenous Arg treatment alone had less or no effect on plant biomass and other metabolites, but in combination with salt, further enhanced growth parameters, MSI and accumulation of soluble protein, phenolic compounds and proline. Arg-induced changes under salinity were associated with decreased lipid peroxidation, flavonoids content and antioxidant enzymes activity. These results show that S. europaea seedlings are well tolerant to applied salt doses. The treatment with exogenous Arg alone affects plant growth slightly, but in combination with salt, synergistically increases growth and salt tolerance of these plants by enhancing the accumulation of proline and antioxidant molecules instead of enzymatic antioxidant.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46107717","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}

Eight localities were processed, each containing two 1m2 plots. The floristic composition of each quadrat was analysed and the presence of two vegetation communities, Festuco-Brometea and Molinio-Arrhenatheretea, was determined. Although indigenous taxa dominate, two invasive plants: Echinocystis lobata (Michx.) Torr. et A. Gray and Erigeron annuus (L.) Desf. have been recorded. Based on the functional traits of taxa, the functional diversity of plots was calculated and compared with the number of taxa and the weight of plant biomass collected within the plots. Functional diversity values ranged from 1.121 to 2.060 and dry biomass from 251.4 to 586.8 g m-2 per quadrat. Correlation analyses linked a decrease in the number of taxa and functional diversity with an increase in biomass and specific leaf area. Functional diversity is positively correlated with the number of taxa, plant dry matter content and leaf dry matter content. It is necessary to conduct this type of research in other grassland communities in Croatia to obtain more detailed insights into the relations of these parameters.","PeriodicalId":6967,"journal":{"name":"Acta Botanica Croatica","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46389100","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}

The morphological investigations carried out on both the types, as well as on several living and dried material collected in southern Sicily, Lampedusa, and Malta (loci classici included), allowed to individuate reliable diagnostic characters that can be used for a correct identification of the two species. The most relevant differential features are: ratio petal/sepal, size and shape of the seed\u0000testa pits, and their arrangement in row number. According to our results, only E. macropoda occurs in the Hyblaean territory (Sicily), which is the locus classicus, whereas E. gussonei occurs on Lampedusa and Maltese islands only.
