ABSTRACT - The production and consumption of organic food has increased significantly worldwide in recent decades, as organic food seems to be a healthy alternative to foods from conventional agricultural systems. Although scientific evidence is still scarce and divergent, there may be greater synthesis of bioactive organic compounds and nutrients in organic cultivation than in conventional cultivation. To gather quantitative evidence demonstrating how agricultural crop systems influence the profile of bioactive compounds, an integrative review was conducted to determine differences in the contents of these substances in vegetables. Of the 270 studies selected, 30 were eligible. Studies have shown that the cultivation system impacts the synthesis of bioactive compounds, with organic crops being those that had the highest concentrations of these substances, in addition to greater oxidative stability. The most significant results were in relation to the concentrations of carotenoids and phenolic acids, and antioxidant activity, which were, on average, 60.57%, 123.28% and 31.29% higher in foods grown in organic systems, respectively, which can be one argument to justify the greater functional potential and health benefits of organic foods. It is also worth noting the importance of encouraging the production and consumption of organic foods, as one of the pillars for building healthy and sustainable food practices as opposed to agriculture based on the agribusiness model and dependence on the use of pesticides. RESUMO - A produção e o consumo de alimentos orgânicos aumentaram significativamente em todo o mundo nas últimas décadas, pois os alimentos orgânicos parecem ser uma alternativa saudável em comparação aos alimentos dos sistemas agrícolas convencionais. Embora as evidências científicas ainda sejam escassas e divergentes, no cultivo orgânico pode haver maior síntese de compostos orgânicos bioativos e de nutrientes do que no cultivo tradicional. Buscando reunir evidências que demonstrem de forma quantitativa como os sistemas de cultivos agrícolas influenciam no perfil de compostos bioativos, uma revisão integrativa foi conduzida para determinar diferenças nos teores dessas substâncias em vegetais. Dos 270 estudos selecionados, 30 foram elegíveis. Os estudos demonstraram que o sistema de cultivo tem impacto na síntese de compostos bioativos, sendo cultivos orgânicos os que apresentaram maiores concentrações dessas substâncias, além de maior estabilidade oxidativa. Os resultados mais significativos foram em relação às concentrações de carotenoides, ácidos fenólicos, e atividade antioxidante, que foram, em média, 60,57%, 123,28% e 31,29% maiores nos alimentos cultivados em sistemas orgânicos, respectivamente, o que justifica o maior potencial funcional e grandes benefícios à saúde de alimentos orgânicos. Cabe destacar também a importância do estímulo à produção e consumo de alimentos orgânicos como um dos pilares para a construção de práticas alimentares saudáveis e sustentáveis em oposição à agricultura pautada no modelo do agronegócio e na dependência no uso de agrotóxicos.

Hancornia speciosa Gomes belongs to the family Apocynaceae and is distributed across different regions of Brazil. The objective of this study was to evaluate callus induction and histodifferentiation in five mangaba accessions under different in vitro culture conditions. Five acessions from the Active Germplasm Bank of Mangaba (Embrapa, Brazil) were evaluated. In vitro-germinated plant seedlings were used for the excision of different explants (internode and node segments, and foliar section). These segments were inoculated in a culture medium containing different concentrations of 6-Benzylaminopurine (BA) and 2,4- Dichlorophenoxyacetic acid (2,4-D). There was a significant effect of accessions, treatments, and time on the callus mass (g). There was no callus induction in the absence of regulators. After 60 days of in vitro culture, all treatments exhibited a linear positive cellular growth. The highest callus mass was observed in the BI accession, in the presence of 22.62 µM 2,4-D and 11.10 µM BA. Hancornia speciosa Gomes pertenece a la familia Apocynaceae, distribuida en diferentes regiones de Brasil. El objetivo de este trabajo fue evaluar la callogénesis y la histodiferenciación en cinco accesiones de mangaba bajo diferentes condiciones de cultivo in vitro. Se evaluaron cinco accesiones del Banco de Germoplasma Activo de Mangaba (Embrapa, Brasil). Las plántulas germinadas in vitro se utilizaron para la escisión de explantes (segmentos nodales e internodales y secciones foliares). Estos segmentos fueron inoculados en un medio de cultivo que contenía diferentes concentraciones de 6-benzilaminopurina (BA) y ácido 2,4-diclorofenoxiacético (2,4-D). Hubo un efecto significativo de las accesiones, los tratamientos y el tiempo del cultivo en la masa de los callos. No hubo inducción de callos en ausencia de reguladores. A los 60 días de cultivo in vitro, los otros tratamientos presentaron un crecimiento celular linear positivo. La mayor masa de callo se observó en la accesión BI, en presencia de 22,62 μM 2,4-D y 11,10 μM BA.
