Abstract
Objetivou-se realizar a caracterização de quatro acessos e duas cultivares de manjericão por características fitoquímicas do óleo essencial e botânico-agronômicas em diferentes épocas de colheita. O experimento foi instalado utilizando-se um delineamento inteiramente casualizado em esquema de parcela subdivida, com quatro repetições. As parcelas consistiram de quatro acessos e duas cultivares de manjericão e as subparcelas por cinco épocas de amostragem. A análise de agrupamento por meio do método Tocher, utilizando as características botânico-agronômicas e fitoquímicas do óleo essencial, promoveu o agrupamento dos acessos silvestres no mesmo grupo evidenciando similaridade entre eles. Os acessos coletados na mesma região formaram grupo conjuntos. Observou-se variação na constituição dos grupos pelos acessos nas diferentes épocas de avaliação por características botânico-agronômicas. A divergência genética entre acessos e cultivares de manjericão, avaliada por características botânico-agronômicas, foi influenciada pelo estádio de desenvolvimento da espécie. A localização geográfica teve influência na caracterização e avaliação da divergência genética entre os acessos. Os constituintes majoritários presentes no óleo essencial das amostras avaliadas foram o linalol, nas cultivares, e o (E)- cinamato de metila, nos acessos silvestres.
Characterization botanical-agronomic and essential oil of basil accessions
Abstract: The objective of this study was to characterize four accessions and two basil cultivars by phytochemical characteristics of essential oil and botanical-agronomic in different harvest times. The experiment was installed in a completely randomized design in a subdivided plot scheme with four repetitions. The plots consisted of four accessions and two basil cultivars and the subplots for five sampling times. The grouping analysis by the method Tocher use botanical-agronomic and phytochemicals of essential oil traits, was efficient in the evaluation of genetic divergence between the accessions and cultivars of basil, as promoted the grouping of the wild accessions in the same group evidencing similarity between them. The accessions collected in the same region formed group together. Variation was observed for the group constitutions by accessions in the different sampling times by botanical-agronomical traits. The genetic divergence among basil accessions and cultivars, evaluated by botanical-agronomical traits, was influenced by development stage of specie. The geographical location influenced the characterization and evaluation of genetic divergence among accessions. The major constituents present in the essential oil of the samples were linalool, in cultivars, and (E) - methyl cinnamate in wild accessions.
