“…Results from literature on the effect of shading on the production of essential oil showed that each species reacts differently. Reduced levels of solar radiation increase essential oil yield in basil plants (Ocimum gratissimum) (Ade-Ademilua et al, 2013) and pariparoba (Pothomorphe umbellate) (Mattana et al, 2010) while decrease in peppermint (Mentha arvensis) (Chagas et al, 2013) and herb-copaiba (Otacanthus azureus) (Serudo et al, 2013). The results of this work indicate that Lavandula dentata can be included in the second group.…”

The objective of this research was to evaluate the effect of successive harvesting times and shading on the production of biomass, yield and phytochemical composition of essential oil in leaves and inflorescences of soilless grown Lavandula dentata. Plants were grown in pots filled with sand, inside a polyethylene greenhouse, in a closed system at UFSM. Plants were harvested at 150, 213 and 320 days after planting date (DAP) in winter, spring and summer, respectively. At 150 DAP, a 50% shading screen was installed. The experimental design was a randomized 3x2 factorial in subdivided plots with 36 plants per subplot. Fresh (FM) and dry mass (DM), yield and chemical composition of essential oil in leaves and inflorescences were determined after each harvest date. The essential oil was extracted, using 70 g fresh mass of leaves and of inflorescences, respectively. Identification and quantification of compounds in the essential oil were determined by gas chromatography/mass spectrometry (GC/MS). The FM of inflorescences was higher on plants harvested 213 DAP grown without shading while of leaves it was higher on plants harvested 320 DAP grown without shading. The yield of the essential oil was higher in the leaves of plants harvested 320 DAP grown without shading. Thirty-one compounds were identified and quantified, being the major ones 1.8 cineol, camphor and linalool, without significant difference among treatments. Three consecutive harvests can be made in August (150 DAP), October (213 DAP) and February (320 DAP) without replacing plants.

“…According to Taiz and Zeiger (2015), plants grown under shading develop thinner leaf blades than plants grown under full sun conditions, and this can be a mechanism of protection of plants against high solar radiations. Similarly, Chagas et al (2013) found that Mentha arvensis L. plants grown under 50% shade screens had changes in leaf and growth characteristics, denoting their phenotypical plasticity when they were grown in environments under different lights; the greater effect of light intensity than light quality on these plants; and that synthesis and accumulation of essential oil can occur under shaded, highly lit environments; however the plants in the treatments under shading had grater leaves with lower oil concentration. Gomes et al (2009) found that Lippia citriodora plants grown under full sun conditions had greater biomass production, and those under 70% shading had higher number of trichomes.…”

Growth Environment and Pot Volume Affect Biomass and Essential Oil Production of Basil1

2020

The objective of this work was to evaluate the effect of pot volume and growth environment on the productions of biomass and essential oil of basil plants (Ocimum basilicum L.). A completely randomized experimental design was used, with five replications, in a 6×2 factorial arrangement consisting of 6 growth environments (full sun; 50% black shade screen; 50% silver shade screen; 50% red shade screen; 35% green shade screen; 150 µm low density polyethylene film - LDPE) and two pot volumes (3.5 L and 5.0 L). The plants were cut and evaluated for variables related to growth, root system, and extraction of essential oil. The growth environments and pot volumes affected the production of biomass and essential oil of the basil plants evaluated. Plants grown under red and silver shade screens had 36.03% and 31.31% higher plant height than those grown at full sun, respectively. Basil plants grown in 5.0-liter pots under black shade screen produced higher essential oil contents. The biomass production of basil plants grown in 5.0-liter pots was affected by the red and green shade screens and LDPE film. The growth of basil plants in 5.0-liter pots under 50% black shade screen is recommended when the crop is intended for essential oil extraction; and their growth in 5.0-liter pots under red shade screen, green shade screen, or LDPE film is recommended when the crop is intended for fresh biomass production.

“…PAULUS et al (2016), verificaram que a massa de matéria seca de plantas de manjericão sob pleno sol foi maior e estatisticamente diferente das plantas dos demais ambientes de luz, resultado diferente do encontrado nesse trabalho. Já CHAGAS et al (2013) em trabalho com hortelã-japonesa, concluíram que isso se deve ao fato desta espécie ter maior sensibilidade à intensidade da luz no que tange ao rendimento de fitomassa das folhas, pois o sombreamento fornecido pelas malhas (50%) foi prejudicial às plantas, qualquer que fosse a cor, não beneficiando quando comparadas às plantas sob pleno sol.…”

“…Devido a capacidade que a luz tem em influenciar no desempenho dos vegetais, surgiu no mercado novo conceito de cultivo, as malhas fotoconversoras, as mesmas alteraram a quantidade e qualidade espectral da radiação solar difundida, gerando variações óticas da luz (CHAGAS et al, 2013). Tais malhas, para chegarem ao mesmo efeito de sombreamento (50%), são unidas mais densamente.…”

RESUMOO manjericão é uma das ervas mais populares e úteis na culinária devido ao seu aroma e sabor, e além disso possui elevados conteúdos de princípios ativos, que apresentam propriedades farmacológicas presentes em inúmeros medicamentos. Avaliou-se diferentes ambientes de luz no rendimento de fitomassa de plantas de Ocimun basilicum L. O trabalho foi realizado entre junho e julho de 2015, na área de experimentos da UFRB, em Cruz das Almas/BA. O delineamento foi o inteiramente casualizado com três tratamentos, os quais constituíram-se de diferentes situações de luminosidade: pleno sol, malha fotoconversora vermelha e malha termo-refletora aluminizada, com dez repetições. Foram avaliadas as seguintes características de fitomassa: a altura da planta, diâmetro do caule, comprimento da raiz, número de folhas, massa da matéria seca das folhas, hastes, parte aérea e raiz, e os índices de clorofila. Houve efeito significativo (p<0,05) através do teste F da ANOVA para o número de folhas, massa da matéria seca das folhas, da parte aérea, das raízes e massa da matéria seca total. PALAVRAS-CHAVE: malhas coloridas, nutrição mineral de plantas, Ocimum basilicum L. PHYTOMASS BASIL GROWN IN DIFFERENT LIGHT ENVIRONMENTS ABSTRACTBasil is one of the most popular and useful in cooking because of its aroma and flavor, and in addition, it has high contents of health services, which cover pharmaceutical products in numerous medicines. The work was carried out in June 2015, in the area of experiments of UFRB, in Cruz das Almas / BA. The design was completely randomized with three treatments, which consisted of different light conditions: full sun, red photoconverter mesh and aluminized thermo-reflective mesh with ten replications. The following phytomass characteristics were evaluated: plant height, stem diameter, leaf length, number of leaves, leaf dry matter weight, stems, shoot and root, and chlorophyll index. There was a significant effect (p <0.05) through the ANOVA F test for leaf number, leaf dry mass, shoot, root and total dry mass KEYWORDS: colored nets, mineral nutrition of plants, Ocimum basilicum L.
