Resumo: | Elicitors are substances with the ability to induce the production of specific secondary metabolites. The objective of this study was to evaluate the effect of chitosan on growth, photosynthetic pigment production and volatile compounds of Mentha arvensison culture medium. Nodal segments of M. arvensiswere inoculated in MS medium supplemented with five chitosan concentrations (0, 50, 100, 150 and 200 mg L-1). After 30 days of cultivation, shoot length, leaf, shoot, root and total biomass were evaluated. In addition, analyzes of volatile compounds and photosynthetic pigments were investigated. The addition of chitosan in 100 mg L-1promoted greater accumulation of dry biomass in all evaluated organs. On the other hand, high concentrations (150 e 200 mg L-1)showed phytotoxic effect on plantlets. Higher levels of chlorophyll aand carotenoids were observed without chitosan and chlorophyll bsupplementation with 200 mg L-1. Chitosan influenced the concentration of volatile constituents in vitro. At the lowest concentration of chitosan (50 mg L-1) there was greater accumulation of pulegone, 100 mg L-1limonene and 200 mg L-1menthol and mentone. |

Objetivou-se avaliar o efeito de quitosana suplementada no meio de cultura no crescimento, produção de pigmentos fotossintéticos e compostos voláteis de Mentha arvensis.Segmentos nodais de M. arvensisforam inoculados em meio MS suplementados com cinco concentrações de quitosana (0, 50, 100, 150 e 200 mg L-1). Após 30 dias de cultivo, avaliou-se o comprimento de brotos, as biomassas secas de folha, caule, raiz e total. Além disso, as análises dos compostos voláteis e pigmentos fotossintéticos foram investigados. A adição de quitosana em 100 mg L-1promoveu maiores acúmulos de biomassas secas em todos os órgãos avaliados. Por outro lado, maiores concentrações de quitosana(150 e 200 mg L-1) apresentaram efeito fitotóxico nas plântulas. Maiores teores de clorofila ae carotenoides foram observados sem a suplementação com quitosana e clorofila bcom 200mg L-1. A quitosanainfluenciou a concentração dos constituintes voláteisin vitro.Na menor concentração de quitosana (50 mg L-1) houve maior acúmulo de pulegona, 100 mg L-1de limoneno e 200 mg L-1de mentol e mentona.Scientia Plena2021-07-13T16:43:48Z2021-07-13T16:43:48Z2020info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfOLIVEIRA, T. de et al.
