Abstract Vegetative propagation methods of acerola cherry are important in standardizing orchards and fruit quality, and the cutting process has been investigated as a promising alternative. The present work aimed to propose the best combination of substrate and cutting type (herbaceous and semi-woody) to provide a greater root rate and seedling development. The trial was conducted in a greenhouse at the State University of Maranhão, in São Luís - MA under intermittent nebulization conditions. The cuttings with dimensions of 10 cm were treated with indole butyric acid (IBA) at a concentration of 2,000 mg L-1, and as substrate were used vermiculite (MV), Plantmax ® (PL) (commercial substrate based on decomposed pine bark), agricultural soil + tanned and sieved bovine manure (S + M) (50% + 50%, v / v); and vegetable soil (VS) composed of fresh soil with the remains of decomposed plants (leaves, stems, bark, and tree fern). The experiment was laid out in a randomized complete design in a 2 x 4 factorial arrangement (2 types of cuttings x 4 substrates) with eight replications with five cuttings per plot. At 60 days after the establishment of the trial, it was concluded that the best combination for rooting cuttings was vermiculite with herbaceous cuttings because they favor a higher rooting rate (95.0%). The alternative substrate composed of soil and tanned bovine manure provided promising results in the rate of rooting (72.5%), root formation, and vegetative development of the aerial part. quality semiwoody semi woody semi-woody Maranhão conditions 1 IBA (IBA 2000 000 2,00 L1, L1 L 1, L-1 MV, MV , (MV) PL (PL commercial bark bark) S M 50% 50 (50 v) VS (VS leaves, leaves (leaves stems fern. fern . fern) ( substrates plot 6 95.0%. 950 95.0% 95 0 (95.0%) 72.5%, 725 72.5% 72 5 (72.5%) formation part 200 00 2,0 L- (MV (5 95.0 9 (95.0% 72.5 7 (72.5% 20 2, 95.

Abstract Food supplements commonly present nutritional quality, especially in plant-origin foods, contributing to the population's quality of life. The use of babassu mesocarp flour in the preparation of food supplements contributes to human nutrition as it is a nutritionally balanced food concerning carbohydrates, proteins, lipids, and minerals. Babassu fruits were collected in five municipalities in the state of Maranhão/Brazil, and the mesocarp was extracted to develop four food supplement formulations per municipality. Firstly, babassu mesocarp flour was prepared in a drying and sterilization process and, subsequently, the manufacturing process of the babassu coconut flour food supplement was added with natural soy extract. The samples were subjected to proximate composition analysis to determine the percentages of carbohydrates, lipids, proteins, moisture, lignin, and energy values (kcal/100 g). The study presented a product rich in carbohydrates (86%), protein values above 10% in the composition, and an average of 19% lipids, presenting a nutritional balance suitable for daily use by the population and even high-performance athletes. plantorigin plant origin foods populations s life proteins lipids minerals MaranhãoBrazil Maranhão Brazil Maranhão/Brazil municipality Firstly subsequently extract moisture lignin kcal/100 kcal100 kcal 100 (kcal/10 g. g . g) 86%, 86 86% , (86%) 10 19 highperformance high performance athletes kcal/10 kcal10 (kcal/1 8 (86% 1 kcal/1 kcal1 (kcal/ (86 kcal/ (kcal (8 (

RESUMO O uso de microrganismos benéficos como os fungos micorrízicos arbusculares (FMA) pode favorecer tanto a fase de crescimento quanto a estabilização das mudas de espécies frutíferas após transplante. O objetivo do estudo foi avaliar o efeito da inoculação de diferentes espécies de FMA no desenvolvimento de mudas de acerola oriundas de estacas herbáceas e semilenhosas. Estacas herbáceas e semilenhosas, previamente enraizadas, foram coladas em tubetes de 500 ml com substrato Plantmax® e inoculadas com três espécies de fungos micorrízicos (Gigaspora margarita - Gimarg, Claroideoglomus etunicatum - Claetun e Glomus clarum - Glclar) isoladas e combinadas (Gimarg+Claetun, Gimarg+Glclar, Claetun+Glclar e Gimarg+Claetun+Glclar). O delineamento estatístico utilizado foi inteiramente casualizado, esquema fatorial 2 x 8 (dois tipos de estacas e oito tipos de inoculação, incluindo o controle sem FMA) com dez repetições. As mudas foram mantidas em casa de vegetação por 100 dias e altura foi mensurada a cada 15 dias para determinação da taxa de crescimento absoluta e relativa (TCA e TCR). Ao final do experimento as mudas foram sacrificadas e determinadas massa fresca e seca da parte aérea e raízes e taxa de colonização micorrízica. Os resultados indicam potencial para a produção de mudas de Malpigia emarginata D.C. por estacas inoculadas com FMA com tendência à redução do tempo para transplantio. A combinação Gimarg+Claetun promoveu maiores taxas de crescimento absoluto e altura de mudas oriundas de estacas herbáceas. A espécie Glomus clarum, isolada ou associada com C. etunicatum promovem maiores taxas de colonização em mudas de origem herbácea e semilenhosas, respectivamente.

ABSTRACT The use of beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) may favor both the growth phase and the stabilization of the seedlings after transplantation. The aim of this study was to evaluate the effect of inoculation of different AMF species on the development of Barbados cherry seedlings from herbaceous and semi-hardwood cuttings. Softwood and semi-hardwood cuttings, previously rooted, were planted in 500 ml tubes filled with Plantmax® substrate and inoculated with three species of mycorrhizal fungi (Gigaspora margarita - Gimarg, Claroideoglomus etunicatum - Claetun and Glomus clarum - Glclar) isolated and combined (Gimarg + Claetun, Gimarg + Glclar, Claetun + Glclar and Gimarg + Claetun + Glclar). The statistical design was completely randomized in factorial scheme 2 x 8 (two types of cuttings and eight types of inoculation, including control without AMF inoculation) with ten replications. The seedlings were kept in a greenhouse for 100 days and height was measured every 15 days to determine the absolute and relative growth rate (AGR and RGR). At the end of the experiment the seedlings were sacrificed and determined height, fresh and dry shoot mass and root and mycorrhizal colonization rate. The results indicate potential for production of Malpighia emarginata D.C. seedlings inoculated with AMF with tendency to reduce the time for transplanting. The Gimarg + Claetun combination promoted higher rates of absolute growth and height of seedlings from herbaceous cuttings. The species Glomus clarum, isolated or associated with C. etunicatum, promoted higher colonization rates in herbaceous and semi-hardwood seedlings, respectively.
