Abstract Ilex paraguariensis, commonly known as yerba mate, is a tree species native to South America. Its commercial value is due to the manufacturing of teas, with potential also in the pharmacological and cosmetic industries. Vegetative propagation of yerba mate is considered an innovation to the traditional production systems based on sexual propagation. The present study aimed to evaluate the rhizogenic potential and chemical attributes of mini-cuttings from 15 yerba mate genotypes, as well as to verify the correlation between phytochemical and rooting-related variables. Mini-cuttings were collected from a pre-existing mini-clonal hedge and the experimental design was completely randomized, with 15 treatments (genotypes), four replications and 10 mini-cuttings per plot. After 120 days, mini-cuttings were assessed regarding rooting, mortality, callogenesis and leaf retention percentages, percentage of mini-cuttings with both calluses and roots, number of roots and average root length. At the time of collection, subsamples from each plot were used for phytochemical analyses including total phenolic compounds, protein, caffeine and theobromine contents and antioxidant activity. Rooting percentages ranged from 5 to 72.5%, with significant variation among genotypes. Adventitious rooting and phytochemical profile of yerba mate mini-cuttings are genotype-dependent. Leaf retention is a relevant factor in the rooting of yerba mate mini-cuttings and the levels of total phenolic compounds, antioxidants and theobromine present in mini-cuttings are negatively correlated components to Ilex paraguariensis adventitious rooting.

O controle da broca-da-erva-mate, Hedypathes betulinus, limita-se ao emprego de práticas silviculturais e catação manual dos insetos adultos, não sendo permitido o uso de inseticidas químicos na cultura. Esta pesquisa teve por objetivos verificar a presença natural de Beauveria bassiana no solo de plantio em monocultura de erva-mate, determinar a persistência de B. bassiana no solo após duas e três aplicações do fungo e averiguar a influência de fatores abióticos na estabilidade do fungo no solo. O estudo foi conduzido em um erval no município de Campo Alegre, Santa Catarina, Brasil, onde foram coletadas amostras de solo em duas áreas, para avaliação da presença natural de inóculos do fungo B. bassiana, procedendo-se à contagem, isolamento e identificação.Não foi detectada a ocorrência natural do fungo no solo em nenhuma das duas áreas. Após essa confirmação, foram realizadas pulverizações com B. bassiana em ambas as áreas, sendo que em uma ocorreram duas e na outra três aplicações. Após a última pulverização, realizada em fevereiro/2006, verificou-se que os inóculos do fungo persistiram por 90 dias na área com duas aplicações e 120 dias na área com três aplicações. A temperatura afetou a persistência do fungo no solo em ambas as áreas, mas a umidade relativa não mostrou influência sobre os inóculos em campo.Palavras-chave: Broca-da-erva-mate; controle biológico; epizootia; fungo entomopatogênico. AbstractPersistence in soil of inoculum of Beauveria bassiana used to control Hedypathes betulinus in yerba maté plantation, Ilex paraguariensis. Control measures of Hedypathes betulinus are restricted to agricultural practices and hand picking of adult insects. No chemical control is allowed in yerba maté cultivation areas. The objectives of this research were to verify the natural occurrence of the entomopathogenic fungus Beauveria bassiana in the soil of yerba maté in monoculture; to determine the persistence of inoculums in the soil after applications of the fungus; and to evaluate the influence of abiotic factors on fungus stability in the soil. The soil samples were taken from two experimental areas in a yerba maté plantation in the county of Campo Alegre, Santa Catarina, Brazil. The samples were analyzed in order to count, isolate and identify inoculums of B. bassiana and other fungi. After the confirmation that B. bassiana was not present in the soil, a suspension of the fungus was applied, twice in one of the areas and three times in the other. After the last application in February/2006, the inoculum persisted for 90 and 120 days, in the area with two and three applications, respectively. The temperature affected the persistence of B. bassiana in soil; however, the relative humidity did not.Keywords: Biological control; epizooty; entomopathogenic fungus; wood borer.

AbstractStudies on strategies to generate cardioprotective effects have been on the rise. Previous work by our group with an ex vivo model of ischemia/reperfusion has shown that both the short-term consumption of yerba mate and exercise can each induce protection of cardiac function independently. Surprising, the two strategies together do not, with an apparent loss of their respective cardioprotection activity. To improve our understanding of the mechanisms involved without reperforming the experiments, we have conducted a retrospective data science-analysis that have produced new insights. The analysis shows that yerba mate generated reductive stress. Alone, this stress increased redox damage in the heart that appears to have led to a protective conditioning. In combination with exercise, the effects of mate inhibited the intermittent ROS generation promoted by exercise alone, which diminished the adaptive response in the heart. These results suggest that an understanding of the molecular mechanisms involved with the yerba mate-promoted reductive stress in cardiac tissue could lead to improved strategies to induce cardioprotection.

Yerba Mate

La Yerba Mate (Ilex paraguariensis St. Hil), es un rubro tradicional del Paraguay desarrollado al inicio de forma extractiva de los bosques y con el fin de aumentar la productividad se alteró su hábitat natural y con ello también la incidencia de insectos que se mantenían en equilibrio originalmente; dándose una especial atención a la Gyropsylla spegazziniana, agente causal del rulo de la Yerba Mate. Al no existir un método de control alternativo para esta plaga, se llevó a cabo este trabajo.
