“…Rodrigues et al (2012), evaluating the chemical composition of the essential oil of the leaves of the species also found α-pinene and β-caryophyllene among the major compounds. In contrast to this work, Paulus et al (2013) observed significant differences in the chemical composition of A. triphylla essential oil, grown at different spacings.…”

“…The height (115.78±12.11 cm) and the diameter (26.79±5.00 mm) were not influenced. Paulus et al (2013) observed significant differences in height of the plants of the Aloysia triphylla specie, when cultivated at larger spacings (1.0 × 1.0 m). According to the authors, with a lower density, there was a uniform distribution of plants per area, facilitating the efficient use of light, water, and soil nutrients.…”

A B S T R A C TThe objective of this study was to evaluate the influence of spacing and mulch on biomass production, chemical composition and production of essential oil of tropical black sage. A randomized block design was used in a 2×2 factorial scheme: two spacings (1.6 × 0.5 m and 1.0 × 0.5 m), with and without mulch, using five replications. In the end, the combination of spacing and presence and absence of mulch did not influence the height and diameter of the stem. However, it has influenced fresh matter: 8765.00 kg ha-1 (1.0 × 0.5 m, with mulch) and 6112.50 kg ha-1 (1.6 × 0.5 m, without mulch). The spacing 1.0 x 0.5 m was what provided higher dry matter (3052.14 kg ha-1). For the production of essential oil, the combination of spacing of 1.0 × 0.5 m, with mulch provided greater production (484.50 kg ha-1). Twenty-seven compounds were detected, of which 23 were identified, most of which were sesquiterpenes and monoterpenes. The α-pinene and the β-caryophyllene showed higher abundances in all samples, regardless of the treatment. The contents of α-humulene was sufficient to meet the requirements of the pharmaceutical industry. Thus, the alteration in soil spacing and mulch influences the production of essential oil and biomass, but it does not influence the relatives amount of the α-humulene and of the β-caryophyllene. Keywords:Varronia curassavica Jacq., α-humulene, β-caryophyllene, mulch, spacing. R E S U M OO objetivo deste estudo foi avaliar a influência do espaçamento e da cobertura morta sobre a produção da biomassa, composição química e produção do óleo essencial de erva-baleeira. Utilizou-se o delineamento de blocos casualizados, em esquema fatorial 2×2: dois espaçamentos (1.6 × 0.5 m e 1.0 × 0.5 m), com e sem cobertura morta, sendo utilizadas cinco repetições. Ao final, a combinação entre espaçamento e presença e ausência de cobertura não influenciaram na altura e diâmetro do caule. No entanto, influenciou na matéria fresca: 8765.00 kg ha-1 (1.0 × 0.5 m, com cobertura) e 6112.50 kg ha-1 (1.6 × 0.5 m, sem cobertura). O espaçamento 1.0 × 0.5 m foi o que proporcionou maior matéria seca (3052.14 kg ha-1). Para a produção de óleo essencial, a combinação do espaçamento de 1.0 × 0.5 m, com cobertura proporcionou maior produção (484.50 kg ha-1). Foram detectados 27 compostos dos quais 23 foram identificados, sendo a maior parte sesquiterpenos e monoterpenos. O α-pineno e o β-cariofileno apresentaram maiores abundâncias em todas as amostras, independente do tratamento. Em todos os tratamentos, o teor de α-humuleno foi suficiente para atender às exigências da indústria farmacêutica. Assim a alteração no espaçamento e na cobertura do solo influencia na produção do óleo essencial, e da biomassa, porém não influencia nos teores do α-humuleno e do β-cariofileno. Palavras-chave:Varronia curassavica Jacq., α-humuleno, β-cariofileno, cobertura vegetal, espaçamento.

“…These results corroborate with the findings of Paulus et al (2013), which affirmed that the plant Aloysia triphylla, in southern Brazil, begin the loss of its leaves in the months of May and June, arriving at a 40% reduction of total leaf mass. During the months of June and July, at the end of autumn and early winter season, with the occurrence of frost, leaf loss rates can reach 100%.…”

Shading greenhouse may be an effective method to achieve a suitable environment for crop growth in subtropical regions. The aim of this study was to evaluate the production of leaves and branches as well as the morphological parameters of height and leaf area of the species Aloysia triphylla, under different shading levels throughout the seasons of the year. A randomized block design in factorial scheme 3x4x6, i.e., three levels of shading (0%, 30% and 50%), four seasons (summer, autumn, winter and spring) and six collection in each season (15, 30, 45, 60, 75 and 90 days after the beginning of each season), with four replications, was used. All evaluations were performed in 2012, since in the first evaluation (summer) the plants had 65 days after transplanting and the last evaluation (spring) the plants had 315 days after transplanting. The dry matter of leaves and branches, leaf area, and plant height were evaluated. The production of the dry matter of leaves and branches, and height and leaf area for the species Aloysia triphylla is influenced by shading levels and the seasons of the year. The variables are highly dependent on the seasonality of meteorological elements such as temperature, solar radiation, rainfall, and frost. In an environment with 0% shading, the dry matter production of leaves was 60.8 % higher in the spring, than those observed for the 30% and 50 % of shading, while this levels resulted higher production in the summer. We showed that the use of shading screens in order to attenuate the solar radiation in places or seasons where there is high light intensity is an effective method to achieve higher production of leaves, which is important source for the oil production.

RESUMO:A variação nos elementos meteorológicos ao longo do ano, configurando as quatro estações, proporciona diferentes condições de crescimento e desenvolvimento das plantas, alterando o metabolismo e a constituição dos tecidos vegetais. Assim, o presente trabalho teve o objetivo de determinar a influência da sazonalidade em parâmetros fenométricos e na produção de óleo essencial em Aloysia triphylla (L'Hérit) Britton, submetida a diferentes níveis de reposição hídrica cultivada em ambiente protegido. As avaliações foram realizadas no dia que marcou a metade de cada estação do ano (verão, outono, inverno e primavera), sendo coletado todo o material vegetativo 20 cm acima do solo. A reposição hídrica foi baseada na evapotranspiração de referência (ETo) para o ambiente externo em função dos dados de entrada da equação de Penman-Monteith a qual apresenta parametrizações para dados obtidos em estações meteorológicas em padrões oficiais, sendo assim aplicados 125, 100, 75 e 50% da ETo em turno de rega de dois dias. A produção de massa fresca, seca e de parte aérea, bem como a área foliar, apresentaram maiores valores na estação primavera, sendo o inverno e o verão responsáveis pelos menores valores. O maior teor de óleo essencial foi observado nas estações de menor produção de biomassa, ou seja, verão e inverno. A reposição hídrica que proporcionou maior produção de material vegetativo foi a de 125% da ETo; no entanto, o maior teor de óleo foi observado nas menores reposições hídricas (75 e 50 % da ETo, respectivamente). A produção de óleo foi maior na primavera, a qual não sofreu influência da reposição hídrica ao longo do ano. Palavras-chave:Planta medicinal, sazonalidade, déficit hídrico, óleo essencial.ABSTRACT: Biomass and essential oil content in Aloysia triphylla (L'Herit) Britton subjected to different levels of water reposition and season alchanges of environmental conditions. The variation in weather elements throughout the year, setting the four seasons, provides different conditions for growth and development of plants, altering the metabolism and the structure of plants` tissues. This study aimed to determine the influence of seasonality on fenometrics parameters and on the oil production in Aloysia triphylla (L'Herit) Britton, subjected to different levels of water availability cultivated in greenhouse conditions. The evaluations were made on the day that marked the middle of each season (summer, autumn, winter and spring), and all plant material were collected 20 cm above ground. The water reposition was based on the evapotranspiration reference (ETo) to the external environment being applied 125, 100, 75 and 50% of ETo in an irrigation interval of two days. The production of fresh, dry and aerial part mass, as well as leaf areamass, showed higher values in the spring season, while winter and summer were responsible for lower values. The highest content of essential oil was observed at seasons with lower biomass production. The water availability that provided higher production of plant material was t...
