Estimativas de parâmetros genéticos de caracteres relacionados ao vigor de estacas em Lippia alba Bragantia
Rufino,Elcio Rodrigo; Siqueira,Walter José; Marques,Márcia Ortiz Mayo; Colombo,Carlos Augusto; Chiorato,Alisson Fernando; Azevedo Filho,Joaquim Adelino; Lourenção,André Luiz; Yamamoto,Paula Yuri; Martins,Antônio Lúcio Mello.
A espécie Lippia alba da família Verbenaceae, aromática e medicinal, é um arbusto nativo com muito vigor e variabilidade genética. O principal interesse dos estudos com esta espécie são os óleos essenciais, cujas funções têm sido comprovadas cientificamente para aplicações nas indústrias de fármacos, cosmética, perfumaria e alimentícia. Apesar desta importância potencial, inexistem pesquisas sobre estimativas de parâmetros genéticos nesta espécie como forma de subsidiar o melhoramento que até o presente momento é incipiente. Este trabalho teve como objetivo, avaliar o potencial genético de Lippia alba, estimando parâmetros genéticos inicialmente em caracteres obtidos em nível de estacas, uma vez que é a forma tradicional de multiplicação da espécie. Os...

Heterogeneity of linalool chemotypes of Lippia alba (Mill.) N.E.Br., based on clonal half-sib progenies Scientia Agricola
Bottignon,Marcos Ribeiro; Rufino,Elcio Rodrigo; Marques,Márcia Ortiz Mayo; Colombo,Carlos Augusto; Azevedo Filho,Joaquim Adelino de; Lourenção,André Luiz; Martins,Antônio Lúcio Mello; Siqueira,Walter José.
Lippia alba (Mill.) N.E.Br. is an aromatic and medicinal shrub native to the American continent. Despite its potential as a source of essential oil for the pharmaceutical and cosmetics industries, few selection and genetic improvement studies have been carried out. The aim of this study was to provide genetic information on this species for breeding programs, showing its selection potential, by investigating clonal half-sib progenies. The following characteristics were evaluated per plant: leaf dry mass (LDM), total dry mass (TDM), leaf yield (LY), essential oil yield (EOY) and oil production (OP). Estimates were made for the several genetic parameters including absolute genetic gain at 30% selection intensity, correlations and relative contribution of...

Interference of heating on the antimicrobial activity and chemical composition of Origanum vulgare L. (Lamiaceae) essential oil Ciênc. Tecnol. Aliment.
Souza,Evandro Leite de; Stamford,Tânia Lúcia Montenegro; Lima,Edeltrudes de Oliveira; Barbosa Filho,José Maria; Marques,Márcia Ortiz Mayo.
Origanum vulgare L. (oregano), Lamiaceae, essential oil has a variety of biological properties and its antimicrobial activity has received a renewed interest for use in food conservation. The aim of this study was to evaluate the interference of heating on the antimicrobial activity and chemical composition of O. vulgare essential oil. The antimicrobial activity of the essential oil kept at room temperature and exposed to different heating temperatures (60, 80, 100 and 120 °C during 1 hour) was evaluated by observing antimicrobial effectiveness at absolute concentration and determining MIC values by the solid medium diffusion procedure. The essential oil chemical composition analysis was performed by GC-MS. O. vulgare essential oil showed interesting...

Performance of ginger grass (Lippia alba) for traits related to the production of essential oil Scientia Agricola
Yamamoto,Paula Yuri; Colombo,Carlos Augusto; Azevedo Filho,Joaquim Adelino; Lourenção,André Luiz; Marques,Márcia Ortiz Mayo; Morais,Guilherme Domingues da Silva; Chiorato,Alisson Fernando; Martins,Antônio Lúcio Mello; Siqueira,Walter José.
Lippia alba (Verbenaceae) is a shrub whose essential oil has important biological, pharmacological, and aromatizing properties. To reach the sustained cultivation of new species with economic potential, the present study aimed to evaluate L. alba performance for fresh leaf matter (FM), leaf dry matter (DM), virus symptoms (VS - Cucumber mosaic virus, CMV), oil yield (OY), and oil chemical composition (OC), and to evaluate DM stability and adaptability. Ten genotypes of four chemical groups (chemotypes) were evaluated in six experiments designed as randomized blocks with two plants per plot, over the whole State of São Paulo, Brazil. A 2.0 x 0.4 x 1.6 m spacing was used in Monte Alegre do Sul and Pindorama, while a 1.0 x 0.4 x 0.6 m spacing was used in...

Shade level effects on yield and chemical composition of the leaf essential oil of Pothomorphe umbellata (L.) Miquel Scientia Agricola
Mattana,Raquel Souza; Vieira,Maria Aparecida Ribeiro; Marchese,José Abramo; Ming,Lin Chau; Marques,Márcia Ortiz Mayo.
Pothomorphe umbellata (L.) Miquel, is a medicinal species that belong to the Piperaceae family and commonly called "pariparoba" and "caapeba". It grows in regions rich in humus, humidity and under the shade of trees, which contribute for its best growth as it is considered a species sciophyte. The effect of shade on the yield and chemical composition of essential oil of Pothomorphe umbellata (Piperaceae) leaves was evaluated. Nine-month-old seedlings were planted in October 2002 and subjected to three shade levels (30%, 50%, 70%) and full sun; the experimental design was in randomized blocks, with four treatments and six replications, in split-plot in time scheme. Two harvests of aerial part were made (05/2003 and 05/2004). Essential oil was extracted by...

Yield and composition of the essential oil of Mentha piperita L. (Lamiaceae) grown with biosolid Braz. J. Plant Physiol.
Scavroni,Joseane; Boaro,Carmen Sílvia Fernandes; Marques,Márcia Ortiz Mayo; Ferreira,Leonardo Cesar.
This research evaluated the effects of biosolid levels on yield and chemical composition of Mentha piperita L. essential oil. Mint plants were grown in a greenhouse in pots containing the equivalent to 0, 28, 56, and 112 t.ha-1 biosolid. Three evaluations were made at 90, 110, and 120 days after planting (DAP). The oil was extracted from the dry matter of shoots by hydrodistillation, and composition was determined by GC/MS. Oil production was slightly affected by the biosolid, increasing when plants were grown with 28 t.ha-1, a condition which did not result in quality improvement. Menthyl acetate was the component obtained at the highest percentage in all treatments. At 90 DAP, plants showed a higher percentage of menthol, the second-highest oil...
