“…As for the essential oil of basil, studies by Alves et al (2015) and Fattahi et al (2019) in pots with soil, Alcantara et al (2018) in the field, and Gondim Filho et al (2018) with the DFT hydroponic system in PVC tubes, found that the essential oil content of basil (Ocimum basilicum L.) did not exceed 1% using supply water for either irrigation or nutrient solution preparation. These values are lower than those recorded in the present study (Table 3).…”

Considering the growing water crisis, using wastewater helps reduce the pressure on good-quality water consumption. In this context, this study aimed to evaluate the growth, production, and essential oil content of Alfavaca Basilicão and Grecco a Palla basil genotypes with a DFT (deep flow technique) hydroponic system adapted to PVC tubes at different recirculation intervals of nutrient solutions prepared with treated domestic effluents. The experiment was performed in a greenhouse with Alfavaca Basilicão and Grecco a Palla basil genotypes analyzed individually. It was a completely randomized design with four replicates in a 2 x 3 factorial scheme: two types of water (public-supply water and wastewater) and three recirculation intervals of nutrient solutions (2, 4, and 6 hours). At 35 days after transplanting, the study evaluated plant height, stem diameter, shoot fresh mass, shoot dry mass, water consumption, water use efficiency, and essential oil content and yield. The types of water did not significantly influence the variables of growth, production, and essential oil content of the basil genotypes. Basil cultivation with the DFT system in tubes is technically feasible with nutrient solutions prepared with treated domestic effluents and recirculation every 2 and 6 hours for Grecco a Palla and Alfavaca Basilicão genotypes, respectively. The means of essential oil content were 1.6 and 1.7% (v/m) for Alfavaca Basilicão and Grecco a Palla genotypes, respectively.

“…Essential oils are active principles activated by the secondary metabolism as a consequence of some stress suffered by the plant [14], common in crops in the conventional system. The biosynthesis of essential oils can be influenced by several factors, such as plant development stage and climatic factors related to temperature, humidity, precipitation, solar radiation and photoperiod [15], whereas the chemical composition of essential oils is determined by genetic factors, development stage, plant age and the interactions among the plant, microorganisms and insects [16]. Due to this diversity, it is important to know the content and composition of the essential oil of the basil variety worked.…”

Basil (Ocimum basilicum L.) is one of the main condiments for fresh consumption and essential oil production. The aim of the present work was to assess the agronomic characterization and analyze the essential oil of 63 basil accessions. The experiment was conducted in two stages in a greenhouse using vases and a hydroponic cultivation system. Oil extraction was performed employing the Soxhlet method. There was a significant variation in the agronomic characteristics among the evaluated accessions. The estimated total contents of essential oils ranged from 0.05 to 0.40%, and the major volatile fraction was methyl-eugenol. In the present study, accessions with superior performance compared to commercial varieties were found. Accession BL11 presented agronomic characteristics suitable for cultivation in a hydroponic system due to its better plant structure and late flowering. Accession BL24 stood out for essential oil extraction, producing 17.6% of linalool and a high intensity of color and odor. Accessions BL11 and BL24 presented market potential, given their higher mass productivity and higher essential oil yield, respectively. These accessions can be made available as new varieties in addition to being used in genetic improvement programs for this species.

“…O manjericão é uma das plantas medicinais e aromáticas mais consumidas no mundo, sendo seu óleo essencial amplamente utilizado nas indústrias químicas, farmacêuticas e de flavorizantes (ALCANTARA et al, 2018). Esta erva medicinal polivalente é conhecida por suas atividades antioxidante, antimicrobiana, anticâncer, antiinflamatória, antinociceptiva, antiúlcera, analgésica, cardiovascular, imunomoduladora, repelente e inseticida, entre outras (PANDEY et al, 2014).…”

RESUMOA luz é um dos fatores que exerce grande influência na morfologia e na fisiologia das plantas aromáticas, pois afeta de forma complexa pela irradiância todas as etapas do crescimento. Neste trabalho, avaliou-se a influência dos diferentes ambientes de cultivo no crescimento vegetativo e na qualidade da muda de manjericão (Ocimum basilicum L.). O delineamento experimental utilizado foi o inteiramente casualizado, com cinco repetições, os quais constituíram-se de diferentes situações de luminosidade por meio de três malhas fotoconversoras (malha vermelha, malha preta e malha aluminizada) e um tratamento a pleno sol (testemunha). Após 30 dias de cultivo foram avaliadas as seguintes características: a altura da planta, número de folhas, massa da matéria seca das folhas, hastes, parte aérea e raiz e suas relações e o índice de qualidade de Dickson. Os resultados foram submetidos à análise de variância e as médias foram comparadas pelo teste de Tukey (p < 0,05). As plantas cultivadas sob as malha termorrefletora, vermelha e preta tiveram incrementos no índice de clorofila a. Plantas de manjericão cultivados a pleno sol tiveram ganhos de 30,55% e 60,27% respectivamente, na massa seca das folhas e raízes em relação aos demais ambientes de luz. Conclui-se que a produção de biomassa e a qualidade das mudas de manjericão são influenciados por diferentes ambientes de luz. Plantas crescidas em condições de pleno sol apresentam maiores incremento na produção de biomassa das plantas de manjericão.Palavras-Chaves: Manjericão, teores de clorofila, sombreamento, ambientes de luz.
