Resumo: In the present research, the effect of spectral control of light was evaluated on anatomical characteristics of Ocimum gratissimum L. leaves. The plants were cultivated during four months under black, red and blue nets with 50% of shade, and full sunlight. Plants grown under full sunlight showed higher leaf thickness, higher stomatal density and higher density of no-glandular and glandular trichomes on the adaxial epidermis. Plants cultivated under colored nets did not show differences in leaf thickness or leaf area. Plants maintained under red net had the lowest stomatal density in adaxial epidermis, as the plants cultivated under blue and red nets exhibited the largest leaf area. The plants maintained under red net showed the smallest stomatal density and the smallest non-glandular and glandular trichomes density in the adaxial epidermis. Such results show that the spectral quality and intensity of light can be modulated during the cultivation of Ocimum gratissimum L. plants in order to obtain desirable anatomical characteristics.

As plantas foram cultivadas por quatro meses sob malhas de 50% de sombreamento nas cores preta, vermelha e azul e a pleno sol. Plantas submetidas a pleno sol apresentaram maior espessura foliar, maior densidade estomática e maior densidade de tricomas tectores e glandulares na face adaxial. As plantas cultivadas sob malhas coloridas não exibiram diferenças quanto à espessura e à área foliar. As plantas mantidas sob malha vermelha tiveram a menor densidade estomática na face adaxial, já as plantas mantidas sob malhas azul e vermelha exibiram maior área foliar total. As plantas mantidas sob malha vermelha apresentaram a menor densidade estomática e as menores densidades de tricomas tectores e glandulares na face adaxial. Tais resultados mostram que tanto a intensidade como a qualidade espectral da luz pode ser modulada durante o cultivo de Ocimum gratissimum L. a fim de serem obtidas características anatômicas desejáveis.Universidade Federal de Santa Maria2018-01-26T12:38:11Z2018-01-26T12:38:11Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMARTINS, J.
