“…The adaptation of yerba mate to tolerate Al can be considered an important evolutionary characteristic because its natural area of distribution is in acidic soils with high Al 3+ saturation (REISSMANN et al, 1999), such as in this study where values higher than 75% was observed (Table 1). The Al 3+ in high concentration in soil solutions could provoke root toxicity; however, Benedetti et al (2017) reported that Al stimulates root growth in yerba mate.…”

“…A number of factors control the elemental composition of yerba mate leaves, for instance, the genetics (BENEDETTI et al, 2017;BARBOSA et al, 2018), leaf age, time between harvesting, index of light (JACQUES et al, 2007), variation between leaves and fruits (BARBOSA et al, 2015), and soil attributes (REISSMANN et al, 1999;CARNEIRO, 2004;BARBOSA et al, 2018). Considering that yerba mate leaves are meant for human consumption, it is necessary to identify its elemental composition and its relationship with soil proprieties, because the soil chemistry can determine the elemental composition and consequently the raw material quality.…”

Yerba mate (Ilex paraguariensis St. Hil.) is a raw material used in making a beverage whose chemical composition can be altered by the growing environment and the management adopted during its cultivation. Thus, it is essential that scientific studies are undertaken to understand the chemical composition of yerba mate related to its growing environment. The aim of this work was to determine the elemental composition in the leaves of yerba mate from native cultivations that had never received fertilization and liming, from the Southern Region of the state of Paraná, Brazil. Soil and leaf samples were collected at 11 sites located in the municipalities of São Mateus do Sul, Mallet, São João do Triunfo, and Lapa. Leaf analyzes were performed in an Optical Emission Spectrometer with Inductively Coupled Plasma. The mean concentrations observed (mg kg -1 ), in decreasing order, were: Ca -7880; K -7310; Mn -2418; -Mg -820; P -720; Al -474; Fe -231; B -78; Zn -62; Ba -62; Cu -8.9; Ni -5.6; Cr -0.82; V -0.53; Co -0.17. The Mn concentrations were directly correlated with Al 3+ saturation and inversely correlated with base saturation, pH, and the available Ca 2+ , demonstrating that changes among these soil components can significantly modify the Mn concentrations in the yerba mate leaves. The high concentrations of Mn and Al in the leaves of yerba mate demonstrate the adaptation of this species to acidic soils with high saturation of Al 3+ . Keywords: Ilex paraguariensis, trace elements, mineral nutrition, soil fertility. Resumo Influência das propriedades químicas do solo na composição elementar das folhas de erva-mate.A ervamate (Ilex paraguariensis St. Hil.) é matéria prima de bebidas cuja composição química pode vir a ser alterada de acordo com o ambiente de cultivo e manejo adotados, tornando-se fundamental trabalhos que discutam a composição química de suas folhas. O objetivo deste trabalho foi determinar a composição elementar de folhas de erva-mate de ervais nativos, que nunca receberam adubação e calagem na região Sul do estado do Paraná. Amostras de solo e folhas de erva-mate in natura foram coletadas em 11 propriedades nos municípios de São Mateus do Sul, Mallet, São João do Triunfo e Lapa. As análises das folhas foram efetuadas em ICP-OES. As concentrações médias observadas em ordem decrescentes em mg kg -1 foram: Ca -7880; K -7310; Mn -2418; -Mg -820; P -720; Al -474; Fe -231; B -78; Zn -62; Ba 62; Cu -8,9; Ni -5,6; Cr -0,82; V -0,53; Co -0,17. Os teores de Mn mostraram-se diretamente correlacionado com a saturação por Al 3+ e inversamente correlacionado com a saturação por base, pH e Ca 2+ disponível no solo, demonstrando que alterações entre estes componentes do solo pode modificar significativamente os teores de Mn nas folhas de erva-mate. Os elevados teores de Mn e Al nas folhas de erva-mate demonstram a adaptação desta espécie para solos ácidos e com elevada saturação por Al 3+ . Palavra-chave: Ilex paraguarienses, elementos-traço, nutrição mineral, fertilidade do solo.

“…Data transformation have been used frequently to approximate the residuals to the normal distribution and to achieve homoscedasticity (Sokal & Rohlf, 2012). For example, in Brazilian Journal of Forestry Research, analysis of variance was one of the most applied statistical test, as can be evidenced in several papers (Amaral et al, 2013;Faria et al, 2013;Freitas et al, 2013;Guareschi & Pereira, 2013;Guimarães Junior et al, 2013;Haliski et al, 2013;Lucena et al, 2013;Maeda & Bognola, 2013;Oliveira & Alixandre, 2013;Pias et al, 2013;Rocha et al, 2013;Rosado et al, 2013;Rossa et al, 2013;Santos et al, 2013;Ataíde et al, 2014;Bastos et al, 2014;Carpanezzi & Gualtieri, 2014;Dias Júnior et al, 2014;Flores et al, 2014;Leite et al, 2014;Medeiros et al, 2014;Mossanek et al, 2014;Oliveira et al, 2014;Prevedello et al, 2014;Protásio et al, 2014;Silva et al, 2014;Souza et al, 2014;Téo et al, 2014;Turchetto & Fortes, 2014;Alves et al, 2017;Benedetti et al, 2017;Boscardin et al, 2017;Cerqueira et al, 2017;Dutra et al, 2017;Freire et al, 2017;Lima & Stap...…”

The analysis of variance is the statistical test most used for comparison of three or more means simultaneously. Its application requires, however, the compliance to some assumptions, with main emphasis on normality of the data and homoscedasticity of variances. When such requirements are not met, one of the alternatives is the data transformation to enable the continuity of the experimental evaluation. With the proposition of the Tukey’s data transformation system, understood as a power transformation system, i.e. the application of nth root on a data set (X⅟n) this statistical procedure has methodologically evolved to ensure such solutions. In the present research we proposed a complement to this system, denominated here as transformation in four steps, with inclusion of two hypothesis tests to evaluate normality and homoscedasticity. This was applied on experimental data to evaluate the amount of radiation available at soil level within stands of Acacia mearnsii De Wild. We have proposed a model for data transformation to simultaneously obtain homoscedasticity and normality. The methodology was appropriate to ensure these two statistical aspects on the experimental data, allowing comparison of eight treatments by conventional analysis of variance. Index terms: Analysis of variance, homoscedasticity, normality.

“…Aluminum toxicity has not been a limiting factor for growth of yerba mate since most plantations do not receive lime to correct soil acidity (Marques et al, 2013). Furthermore, there are indications of greater growth of root systems when Al is used in nutrient solutions (Benedetti et al, 2017). However, the combination of abiotic factors (e.g., high acidity and high Mn concentrations in some soils) with genetic factors of this species, suggests that yerba mate is a species with a high capacity for accumulating metals.…”

Yerba mate (Ilex paraguariensis St. Hill.) has shown a relatively high capacity for metal absorption and accumulation under field conditions. To further evaluate the accumulation capacity of Ni and Zn, yerba mate clonal seedlings were grown in containers under five rates of Ni or Zn (0, 0.5, 2, 10, and 40 mg kg-1) with three soils originating from different parent material (basalt, rhyodacite, and sandstone). After 10 months, plants were harvested, divided into component parts (leaves, branches, and roots), and evaluated for 12 elements. Use of Zn and Ni enhanced seedling growth under rhyodacite-and sandstone-derived soils at the first application rate. Application of Zn and Ni resulted in linear increases based on Mehlich I extractions; recovery of Ni was smaller than Zn. Root Ni concentration increased from approximately 20 to 1000 mg kg-1 in rhyodacite-derived soil and from 20 to 400 mg kg-1 in basalt-and sandstone-derived soils; respective increases in leaf tissue were ~3 to 15 mg kg-1 and 3 to 10 mg kg-1. For Zn, maximum obtained values were close to 2000, 1000, and 800 mg kg-1 for roots, leaves, and branches for rhyodacite-derived soils, respectively. Corresponding values for basalt-and sandstone-derived soils were 500, 400, and 300 mg kg-1, respectively. Although yerba mate is not a hyperaccumulator, this species has a relatively high capacity to accumulate Ni and Zn in young tissue with the highest accumulation occurring in roots.
