Produção de mudas de Aloysia gratissima (Gillies & Hook.) Tronc. por meio da propagação sexuada e assexuada

Abstract: RESUMO:A alfazema-do-Brasil é planta de importância medicinal, como produtora de terpenos. A principal descrição etnofarmaco-botânica aponta como sendo eficaz para infecções brônquicas, pulmonares e da bexiga. O objetivo do trabalho foi estudar a propagação de A. gratissima visando a obtenção de mudas. Na propagação sexuada estudou-se a influência da temperatura na presença e ausência de luz e três épocas de coleta das sementes (março, junho e setembro). Na propagação via semente foram testados três diferentes… Show more

“…In cuttings of Aloysia gratissima (Gillies and Hook.) Tronc., a higher rooting percentage was observed in herbaceous cuttings, as they showed higher retention of leaves when compared to semi-woody cuttings, with leaves being an endogenous source of auxin (SANTOS et al, 2009). As in this work, the same amount of buds and leaves per cutting was kept, and so this may explain the fact that there was no difference in the rooting percentage, even with the supply of exogenous auxin, probably because the species has this phytohormone in sufficient levels, since it presented rooting without the need of IBA.…”

“…It is a bush used in folk medicine for the treatment of bronchial infections, lung diseases, bladder disorders, and as an antispasmodic. It is also used as an antimicrobial agent and as a flavoring for infusions and meat (Pinto et al, 2007;Santos et al, 2009). It grows spontaneously and is commonly pollinated by insects, especially bees, during its flowering.…”

“…Resultados semelhantes ao presente ensaio, também foram observados por Lima et al (2011) e Santos et al (2009) em que, o uso de estacas mais lignificadas apresentaram maior dificuldade na formação de raízes quando comparadas com estacas menos lignificadas. Segundo Fachinello et al (2005), este comportamento está relacionado ao tipo de tecido presente nas regiões menos lignificados, menos diferenciados, maior concentração de promotores e proximidade das regiões de síntese de auxinas.…”
