“…Although literature shows that aluminum and iron toxicity at low pH can directly influence plant development (Lopes and Cox, 1977;Haridasan, 2008), leading to the development of scleromorphic characters in cerrado plants (Goodland, 1971), the levels of iron and aluminum in the soil did not harm the development of Aldama grandiflora plants. Furthermore, A. grandiflora showed an anatomical stem development very similar to other species of the group already described (Bombo et al, 2012(Bombo et al, , 2014Oliveira et al, 2013;Silva et al, 2014;Bombo et al, 2016), indicating a consistency within the genus and that this species is well adapted to these soil conditions. In this study, A. grandiflora showed considerably consistency in leaf and stem anatomical characteristics since only slight morphometric differences were found among the populations analyzed.…”

“…This species is characterized by intraspecific structural variations and high degree of polymorphisms in color and shape of the leaf blade since its representatives are tolerant to different light intensities (Magenta and Pirani, 2014). Several taxonomic studies have been conducted on Brazilian Aldama species (Bombo et al, 2012(Bombo et al, , 2014Oliveira et al, 2013;Silva et al, 2014); however, such studies have addressed only the qualitative anatomical characters of these species, but not the quantitative traits.…”

Vegetative aerial organs are considerably more exposed to environmental conditions and can reflect the specific adaptations of plants to their local environment. Aldama grandiflora species are known to be widely distributed in Brazil; therefore, individuals from different populations of this species are thought to be exposed to different abiotic and biotic conditions. Several anatomical studies conducted on Brazilian Aldama species have mainly focused on the qualitative anatomical characters or traits of these species, but not on their quantitative traits. In this study, we evaluated whether climate and soil conditions can change the morphometry among individuals of A. grandiflora collected from six sites in the Goiás State, Brazil, by assessing their anatomical characters. Further, soil sampling was performed, and climate data were collected from all the six sites. The analysis indicated few statistical differences among the populations evaluated, showing that A. grandiflora presented consistent leaf and stem anatomical characteristics. The small morpho-anatomical differences found among individuals of the different populations evaluated, reflected the soil conditions in which these populations were grown. Therefore, environmental factors have a significant influence on the morpho-anatomy of Aldama grandiflora.Keywords: cerrado, Compositae, morphometry, phenotypic plasticity, leaf anatomy. Condições climáticas e de solo podem alterar a morfo-anatomia entre indivíduos de diferentes localidades? Um estudo de caso emAldama grandiflora (Asteraceae) ResumoOs órgãos vegetativos aéreos estão consideravelmente mais expostos às condições ambientais e podem refletir as adaptações específicas das plantas ao seu habitat. A espécie Aldama grandiflora é amplamente distribuída no Brasil e, dessa forma, indivíduos de diferentes populações podem estar expostos a diferentes condições ambientais. Vários estudos anatômicos realizados com espécies brasileiras do gênero Aldama têm abordado, principalmente, as características anatômicas qualitativas dessas espécies, mas não em suas características quantitativas. Neste estudo avaliamos se as condições climáticas e do solo podem alterar a morfometria entre os indivíduos de A. grandiflora coletados em seis populações do Estado de Goiás. Foram avaliados os caracteres anatômicos foliares e caulinares, além da amostragem do solo e coleta de dados climáticos, para os seis locais. A análise indicou algumas diferenças estatísticas entre as populações avaliadas, mostrando que A. grandiflora apresentou características anatômicas foliares e caulinares bastante consistentes.As pequenas diferenças morfo-anatômicas encontradas entre indivíduos das diferentes populações avaliadas, refletiram as condições do solo nos quais essas populações se desenvolveram. Assim sendo, fatores ambientais relacionados ao clima e condições do solo têm uma influência significativa sobre a morfo-anatomia de Aldama grandiflora.

“…For A. robusta, ten compounds were exclusive, and germacrene D, one of the major sesquiterpenes in the EOs from this species, exhibits antimicrobial activity (Murari et al 2008). Exclusive compounds, as presented here for A. arenaria and A. robusta, along with the common compounds to each species, provide a characteristic chemical profile that can help in solving taxonomic problems among Aldama species (Bombo et al 2012(Bombo et al , 2014.…”

“…Thus, the increase in monoterpenes in EOs during the dormant stage of the species studied herein may be interpreted as a chemical defence mechanism in a plant that not only survives in conditions unfavorable to growth but also has only an underground system to maintain itself until the next growth stage (Bombo et al 2014).…”

Aldama arenaria and A. robusta are morphologically similar aromatic species that have seasonal development. The yield and chemical composition of essential oils from aerial and underground vegetative organs of these species were compared to verify the production of volatile metabolites in flowering and dormant phases of development and to identify if there are unique compounds for either species. The major compound in the essential oils from A. arenaria leaves was palustrol (16.22%) and for aerial stems was limonene (15.3%), whereas limonene (11.16%) and α-pinene (19.64%) were the major compounds for leaves and aerial stems from A. robusta, respectively. The major compound for the underground organs was α-pinene, in both species and phenological stages. High amounts of diterpenes were found especially for A. arenaria essential oils. Each analyzed species presented unique compounds, which can provide a characteristic chemical profile for both species helping to solve their taxonomic problems. This study characterized for the first time the yield and essential oil composition of A. arenaria and A. robusta, which have medicinal potential, and some of the compounds in their essential oils are unique to each one and may be useful in helping the correct identification of them.
