Phenotypical, phytochemical and molecular characterization of "capim-carona" [Elionurus muticus (Spreng.) Kuntze] populations

Abstract

Elionurus muticus naturally occurs in southern Brazil and its economic potential is due to the presence of essential oils. There are few studies about this genus. Thus, the aim of the present study was to characterize native E. muticus populations. The study was performed with five "capim-carona" populations collected in the state of Rio Grande do Sul, totaling 50 plants grown in pots in the Agronomy School. All five E. muticus populations presented variability for phenotypic traits and phenolic compound concentration. The presence of citral was identified in all populations, except in that from the "Morro da Polícia" region. RAPD analysis showed high variability for these populations, allowing the separation of individuals into five groups according to their geographic origin. The highest variability occurred within each population. Based on the results, the populations from São Borja and Agronomy School can be recommended to be used in breeding programs.

Genetic and cytogenetic structure of wild lemon grass (Elionurus muticus ) populations

“…The results indicate that differences in ecosystems may reflect the molecular analysis and that the variation may be attributed to differences in the number of alleles per locus and their distribution within the population. The relationship between genetic variability and geographic distribution has been observed in various aromatic plants (Füller et al 2010, Zhang et al 2013). …”

Elionurus muticus as an Alternative Source of Citral from Pampa biome, Brazil

“…In the central region, the presence of camphene 11.5 , E -caryophyllene 17.9 , and spathulenol 18.6 as major components was verified 19 . In southern Brazil, especially in the border regions with Argentina and Uruguay, geranial and neral are present as major constituents of the essential oil 20 .…”

Biochemical and Molecular Analysis of Some Commercial Samples of Chilli Peppers from Mexico

“…Previously, the content and composition of fatty acids were tested as taxonomic markers in Hippophae rhamnoides L., showing that these substances, such as linoleic acid, can be used as biochemical markers for this species [ 15 ]. On the other hand, Füller et al [ 16 ] analyzed the variability of morphological characteristics as well as the content of phenolic compounds and essential oils in plants from southern Brazil. Moreover, Rotini et al [ 17 ] described the state of preservation of a meadow by comparing the content of phenolic compounds and the RAPDs.…”
