Resumo: | Mentha x gracilis Sole (Lamiaceae), known as gingermint, is a medicinal species of great importance, whose pharmacological properties are associated with the production of essential oil, with is rich in monoterpenes. This study aimed at evaluating the impact of different light regimes on a M. x gracilis clone. The plants were cultivated under shading (30% and 60%) and in full sunlight for 105 days. Subsequently, the leaf samples were submitted to morphometric analysis (leaf area, thickness, hardness, stomatal index and trichome density). The different conditions of light intensity promoted distinct changes in leaf morphology and anatomy. Plants cultivated in full sunlight were harder, thicker and presented a higher density of trichomes while plants grown under 30%-60% shade presented higher stomata density and leaf area. |

O presente estudo objetivou avaliar o impacto de diferentes regimes de luz em um clone de M. x gracilis. As plantas foram cultivadas por 105 dias sob sombreamento (30% e 60%) e sol pleno. Durante 90 dias de cultivo, o comprimento do caule foi avaliado quinzenalmente. Posteriormente, amostras de folhas foram submetidas a análises morfométricas (área, espessura, dureza, índice estomático e densidade de tricomas) e comprimento dos entrenós. As diferentes condições de intensidade luminosa promoveram alterações morfológicas e anatômicas. As plantas cultivadas em pleno sol apresentaram maior dureza, espessura e densidade de tricomas enquanto as plantas cultivadas a 30% e 60% de sombreamento obtiveram maiores índices estomáticos, área foliar e comprimentos caulinares e dos entrenós.Universidade Federal de Santa Catarina (UFSC)2020-05-01T22:21:51Z2020-05-01T22:21:51Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPEGORARO, R.
