Boaventura Filho,Marco Aurélio; Leite,Marco Aurélio; Leod,Lelia Mc; Santos,Breno Régis; Santos Filho,Plinio Rodrigues dosABSTRACT Bowdichia virgilioides Kunth is a medium size tree used in folk medicine and in furniture manufacturing which makes it a target of extractive processes. The aim of this work was to evaluate the endogenous content of polyamines, amino acids, and sugars in seedlings of Bowdichia virgilioides that presented or not the development of spontaneously differentiated vegetative propagules in their roots. An ave...
Tomato production in hydroponic system using different agrofilms as greenhouse ...
Marques,Douglas José; Matheus Filho,Edmur; Bianchini,Hudson C; Veroneze Junior,Valdir; Santos,Breno Régis; Carlos,Lanamar de A; Silva,Ernani Clarete daABSTRACT Protected cultivation has increased over the years. More studies on the benefits of using photoselective agrofilms are necessary. The choice of material to cover the greenhouse is a decisive factor for crop development and production. The aim of this study was to evaluate the effect of diffuser and blue-colored agrofilms on the production of different tomato cultivars of indeterminate growth habit unde...
Multiplication and in vitro rooting of Handroanthus impetiginosus (Mart. Ex DC....
Máximo,Wesley Pires Flausino; Santos,Breno Régis; Martins,João Paulo Rodrigues; Beijo,Luiz Alberto; Barbosa,SandroAbstract This study aimed to evaluate cytokinin influence during in vitro multiplication stage and activated charcoal in combination with indole-3-butyric acid (IBA) during in vitro rooting of Handroanthus impetiginosus. For in vitro multiplication, nodal segments of shoots obtained from in vitro seedlings establishment were inoculated in Woody Plant Medium (WPM), with and without the following concentrations o...
Effect of Salicylic Acid, 2,4-D and 2i-P on the Production of Secondary Metabol...
Teixeira,Maria Gessi; Carvalho,Marília; Leite,Marco Aurélio; Barbosa,Sandro; Santos filho,Plinio Rodrigues dos; Santos,Breno RégisAbstract The aim of this work was to evaluate the effect of Salicylic acid, 2,4-D and 2-iP on the production of total phenolic and flavonoids as well in the levels of fukugetin and 7-epiclusianone in callus of Garcinia brasiliensis zygotic embryos. For this, Bacupari callus were exposed to different concentrations (0.0; 0.1; 1; 10; 100 µM) of Salicylic acid (SA) in the presence or in the absence of 72 μM 2-iP a...
Water Erosion in Oxisols under Coffee Cultivation
Mendes Júnior,Henrique; Tavares,André Silva; Reis dos Santos Júnior,Walbert; Silva,Marx Leandro Naves; Santos,Breno Régis; Mincato,Ronaldo LuizABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication of water bodies. Estimation of soil losses due to water...
Soil microbial activity and hairy beggarticks’ germination after application of...
Caixeta,Matheus Ramos; Carvalho,Saul Jorge Pinto de; Colpa,Poliana Coste e; Andrade,Márcio Donizetti de; Santos,Breno RégisABSTRACT Biodiesel stands out as an alternative for petroleum-based products, but its production generates a large amount of by-products. This study was carried out at the Instituto Federal de Educação, Ciência e Tecnologia do Sul de Minas Gerais, Campus Machado, with the objective of evaluating the impacts of the disposal of crude glycerin on agricultural soil and its microbial activity as well as in plant dev...
USO DE BIORREATORES DE IMERSÃO CONTINUA, TEMPORÁRIA E MEIO DE CULTURA SEMISSÓLI...
Mendonça,Evânia Galvão; Stein,Vanessa Cristina; Carvalho,Humberto Henrique de; Santos,Breno Régis; Beijo,Luiz Alberto; Paiva,Luciano VilelaRESUMO A micropropagação em sistemas de biorreatores é considerada como uma forma de reduzir os custos de produção por meio do escalonamento de automatização do processo. O objetivo desse trabalho foi desenvolver um protocolo eficiente de produção de mudas de Eucalyptus camaldulensis em diferentes tipos de sistema, incluindo biorreator de imersão continua e temporária. Para isso, meristemas apicais (1 mm) e mer...
Teor de nutrientes e trocas gasosas em plantas de copo-de-leite cultivadas em s...
Landgraf,Paulo Roberto Corrêa; Marques,Douglas José; Mantovani,José Ricardo; Silva,Adriano Bortolotti da; Santos,Breno RégisResumo: O objetivo deste trabalho foi avaliar o efeito do cultivo de plantas de copo-de-leite (Zantedeschia aethiopica) em sistema hidropônico, no crescimento vegetativo, no teor de nutrientes na parte aérea e nas trocas gasosas. Utilizou-se o delineamento experimental inteiramente casualizado, em arranjo fatorial triplo (2x2x2), com oito tratamentos, três repetições e oito plantas por parcela. Os tratamentos c...
Growth curve, biochemical profile and phytochemical analyses in calli obtained ...
Santos Filho,Plinio Rodrigues dos; Santos,Breno Régis; Barbosa,Sandro; Vieira,Letícia Rios; Freitas,Natália Chagas de; Dias,Daniele FerreiraGarcinia brasiliensis, popularly known as Bacupari, is native to the Amazon and commonly used in folk medicine for its therapeutic properties. This plant is rich in bioactive compounds like benzophenones. However, there are no works about the in vitro establishment and achievement of secondary metabolites in this plant. Thus, the aim of this work was to determine the growth curve and to perform the biochemical ...
Heavy metals availability and soil fertility after land application of sewage s...
Moreira,Rodrigo Santos; Mincato,Ronaldo Luiz; Santos,Breno RégisSewage sludge is the solid residue obtained from urban sewage treatment plants. It is possible to use the sludge in a sustainable way as fertilizer and as soil conditioner due to its high levels of organic matter and nutrients. Besides pathogens and volatile organic compounds, the residue may also contain heavy metals which may accumulate and contaminate crops and the food chain. The aim of this study was evalu...
