Título: Chemical composition and functional properties of chocolate cakes formulated with yacon tube roots (Smallanthus sonchifolius)
Fonte: Rev. Inst. Adolfo Lutz;71(2):301-307, abr.-jun. 2012. tab.
Idioma: en.
Resumo: This present work aimed at developing a cake using yacon flour (20% and 40%), for replacing partially thew heat flour. The products were characterized on the nutritional composition, glycemic index, glycemic charge and in vitro prebiotic effect. The physico chemical analyses showed a high fiber concentration in the experimental cakes, in compliance with the legislation in force, being 7.49g% for the cake A (yacon 20%)and 10.75g% for the cake B (yacon 40%). Low concentrations of available carbohydrates of 11.22g% and 9.35g% were found in both cake A and B, respectively. Glicemic index lower than 55 and glycemic chargelo wer than 10 were detected. The prebiotic effect was observed by keeping the lactic bacteria above 106UFC/g of substrate. On that account, cakes containing high fiber concentrations were achieved. Regard lessof the added amounts of yacon flour to the experimental cakes, they were classified as of low glycemic index and glycemic charges products, besides their in vitro prebiotic effect.

Título: Propagação vegetativa por miniestacas de preciosa (Aniba canellila (HBK) MEZ) / Vegetative propagation by mini-cuttings of preciosa (Aniba canelilla (HBK) Mez)
Fonte: Acta amaz;40(4):687-692, dez. 2010. ilus, graf, tab.
Idioma: pt.
Resumo: Este trabalho teve como objetivo o enraizamento de miniestacas de material juvenil da preciosa (Aniba canelilla (H.B.K) Mez), tratadas com diferentes concentrações de ácido indol-3-butirico (AIB) na forma líquida. As miniestacas foram obtidas de mudas de regeneração natural com aproximadamente um ano de idade e modeladas com 5 cm de comprimento e 0,4 - 0,6 mm de diâmetro. O experimento foi conduzido em casa de vegetação, com sistema de nebulização intermitente regulada em 20 segundos para aspersões com intervalos de 20 minutos. Como substrato foi utilizado areia lavada. Semanalmente foram feitas aplicações de fertilizante foliar e fungicida. O experimento foi delineado em cinco blocos inteiramente ao acaso, com cinco tratamentos (0, 300 ppm, 600 ppm, 1200 ppm e 2000 ppm de AIB) com 25 miniestacas/tratamento, totalizando 125 miniestacas no experimento. Após 180 dias do plantio, as miniestacas foram retiradas do substrato e avaliados os seguintes parâmetros: porcentagem de enraizamento, porcentagem de sobrevivência, porcentagem de calo; porcentagem de brotos; número de raízes principais, comprimento médio das raízes; peso da matéria seca dos brotos e peso da matéria seca das raízes. Os resultados indicam que a emissão de raízes das estacas de material juvenil da preciosa independe do uso do AIB. Entretanto, o uso desta auxina na concentração de 2000 ppm estimulou o enraizamento (79,04 por cento); sobrevivência (89,43 por cento) e brotação (64 por cento) das miniestacas.

This study aimed to the rooting of minicuttings of juvenile material of preciosa (Aniba canelilla (H.B.K) Mez), through the use of concentrations of 0, 300 ppm, 600 ppm, 1200 ppm and 2000 ppm of acid indole-3-butirico (IBA) in liquid form. The cuttings were obtained from seedlings of natural regeneration with approximately one years of age and shaped with 5 cm long and 0.4 - 0.6 mm in diameter. The experiment was conducted in a greenhouse, with intermittent mist system governed by 20 seconds to mist at intervals of 20 minutes. As substrate was used sand washed. Weekly applications were made from fertilizer and foliar fungicide. The design used was completely randomized with five treatments and twenty-five repetitions, totaling 125 minicuttings. After 180 days after planting, the minicuttings were taken from the substrate and evaluated the following parameters: percentage of rooting, percentage of survival, percentage of calluses, dry weight of the sprouts, number, size and dry weight of roots. The results indicate that the rooting of minicuttings of juvenile material of preciosa independent of the use of the IBA. However, the use of auxin in the concentration of 2000 ppm stimulated rooting (79.04 percent), survival (89.43 percent) and sprouted (64 percent) of minicuttings.

Título: Effect of phosphorus on arsenic uptake and metabolism in rice cultivars differing in phosphorus use efficiency and response
Fonte: An. acad. bras. ciênc;89(1):163-174, Jan,-Mar. 2017. graf.
Idioma: en.
Resumo: ABSTRACT A hydroponic experiment was carried out to investigate the effect of phosphorus (P) nutrition on arsenic (As) uptake and translocation within the seedlings of rice cultivars. The experiment occurred in three stages: I 5 days of acclimatization (nutritive solution); II 10 days under P (0.0 and 0.09 mM) and As (0.0 and 100 mM) treatments; III 5 days under recovery. The As exposure had significant effect reducing dry weights of shoots or roots, resulted in elevated concentrations of As in shoot tissues. BR-IRGA 409 showed the highest susceptibility to As in biomass production and root system parameters regardless the P level. This cultivar showed contrasting responses of As translocation to shoot tissue dependent on P levels, with the highest As concentration under low P and lowest under normal P levels. P nutrition was most striking on plants recovery for all cultivars under As exposure. Clearer separation of cultivars for phosphorus use efficiency (PUE) occurred at lower shoot P contents, that was, at higher levels of P deficiency stress. IRGA 424 showed higher PUE as compared to the others cultivars. Our results go some way to understanding the role of P nutrition in controlling the effects of As in rice shoots.

Título: Compatibility of Azospirillum brasilense and Pseudomonas fluorescens in growth promotion of groundnut ( Arachis hypogea L)
Fonte: An. acad. bras. ciênc;89(2):1027-1040, Apr.-June 2017. tab, graf.
Idioma: en.
Resumo: ABSTRACT We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. Among all the bacteria tested, Rhizobium was found to inhibit the growth of other bacteria. From the compatible group of PGPR, we have selected one biofertilizer (Azospirillum brasilense strain TNAU) and one biocontrol agent (Pseudomonas fluorescens strain PF1) for further studies in the pot culture. We have also developed a bioformulation which is talc powder based, for individual bacteria and mixed culture. This formulation was used as seed treatment, soil application, seedling root dip and foliar spray in groundnut crop in vitro germination conditions. A. brasilense was found to enhance the tap root growth and P. fluorescens, the lateral root growth. The other growth parameters like shoot growth, number of leaves were enhanced by the combination of both of the bacteria than their individual formulations. Among the method of application tested in our study, soil application was found to be the best in yielding better results of plant growth promotion.

Título: Shoot and root interference of morning glory on the initial growth of sugarcane
Fonte: An. acad. bras. ciênc;90(1):521-528, Mar. 2018. tab, graf.

Resumo: ABSTRACT Among weeds, morning glories comprise a very important group of climbing plants that infest sugarcane crops. The objective of this study was to evaluate the shoot and root interference of Merremia cissoides on the initial growth of sugarcane cultivar RB 966928. The experiment consisted of five treatment groups: (i) sugarcane monocropping, (ii) morning glory monocropping, (iii) sugarcane intertwined with morning glory but inseparate boxes, (iv) sugarcane intertwined with morning glory in attached boxes and (v) sugarcane with morning glory in attached boxes with morning glory prevented from intertwining with the sugarcane. The experimental design consisted of randomized blocks with four replicates. Merremia cissoides adversely affected the initial growth of the RB 966928 sugarcane starting at 90 days after transplanting (DAT). This effect increased with the time of intercropping, reaching at 180 DAT with a reduction of 57.3% in height,15.5% in stalk diameter, 90.4% in leaf areas, 86.6 and 75.2% in stalk and leaf dry mass, respectively. These reductions primarily due to the weed intertwining with the sugarcane plants because the weed had a physical choking and shading effect. This negative effect of morning glory on the sugarcane plants increased when they shared the substrate (i.e., when they competed for space and water), which also adversely affected weed growth, reducing 50.2% leaf areas and 42.1% shoot dry mass. The leaf area and the stalk and leaf dry mass of sugarcane are the characteristics more sensitive to the weed interference. Thus, both the shoot and root of M. cissoides interferes negatively in the growth of sugarcane, with the effect proportional to the period of coexistence, highlighting the detrimental effect on the stem (greater economic interest), and may also compromise the mechanical harvesting of the crop.

Título: Anatomical and histochemical comparison of the primary and adventitious roots of Attalea microcarpa (Arecaceae) at the initial growth stage
Fonte: Acta amaz;49(4):311-315, out. - dez. 2019.
Idioma: en.
Resumo: We describe the anatomical structure of roots originating from the apocole of Attalea microcarpa compared to the primary root, by means of usual methods for optical microscopy. The adventitious roots are differentiated in the apocole associated to vascular bundles, and can remain as a single structure or branch. They have the basic root structure characteristic of Arecoideae palms, without schizogenous spaces, which are observed in the primary root, in addition to few air spaces. Mucilages, starch and proteins were present in both types of roots. Adventitious roots of the apocole are described for the first time in Arecaceae. (AU)

Título: Effectiveness of Arbuscular Mycorrhizal Fungal Isolates from the Land Uses of Amazon Region in Symbiosis with Cowpea
Fonte: An. acad. bras. ciênc;90(1):357-371, Mar. 2018. tab, graf.
Idioma: en.
Resumo: ABSTRACT Arbuscular mycorrhizal fungi provide several ecosystem services, including increase in plant growth and nutrition. The occurrence, richness, and structure of arbuscular mycorrhizal fungi communities are influenced by human activities, which may affect the functional benefits of these components of the soil biota. In this study, 13 arbuscular mycorrhizal fungi isolates originating from soils with different land uses in the Alto Solimões-Amazon region were evaluated regarding their effect on growth, nutrition, and cowpea yield in controlled conditions using two soils. Comparisons with reference isolates and a mixture of isolates were also performed. Fungal isolates exhibited a wide variability associated with colonization, sporulation, production of aboveground biomass, nitrogen and phosphorus uptake, and grain yield, indicating high functional diversity within and among fungal species. A generalized effect of isolates in promoting phosphorus uptake, increase in biomass, and cowpea yield was observed in both soils. The isolates of Glomus were the most efficient and are promising isolates for practical inoculation programs. No relationship was found between the origin of fungal isolate (i.e. land use) and their symbiotic performance in cowpea.

Título: Phytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae) / Potencial fitotóxico de folhas jovens de Blepharocalyx salicifolius (Kunth) O. Berg

Resumo: Abstract The loss of leaves by plant species found in the Cerrado (Brazilian savanna) is an energetically expensive process due to adverse environmental conditions and predation by herbivory. The mature leaves have adaptations which minimize these events. However, the young individuals lack these structures and produce high leaf concentrations of secondary metabolites as a form of protection. These compounds can be used in bioprospection of natural herbicides. Thus, this study aimed to evaluate the phytotoxicity of hexane, ethyl acetate and aqueous extracts of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg on the elongation of wheat coleoptiles (Triticum aestivum L.) and evaluate the potential phytotoxic of ethyl acetate extract on germination, growth and cell size of metaxylem of sesame (Sesamum indicum L.) seedlings. The hexane and ethyl acetate extracts inhibited the elongation of wheat coleoptiles at all concentrations; however, the most promising results were observed in coleoptile fragments treated with the ethyl acetate extract. This treatment changed the mean germination time and the synchrony of sesame seeds, inhibited the growth of shoots and roots, reduced the dry weight of seedlings, led to abnormalities in the seedlings and reduced the length of the metaxylem cells in the sesame seedlings. These results demonstrated the phytotoxic potential of young leaf extracts of B. salicifolius and the high phytotoxicity of the ethyl acetate extract in the initial development of S. indicum.

Resumo A perda das folhas pelas plantas do Cerrado é um processo energeticamente custoso devido às condições ambientais adversas e intensa predação por herbivoria. As folhas maduras possuem adaptações que minimizam esses eventos. Entretanto, os indivíduos jovens carecem dessas estruturas e produzem elevadas concentrações foliares de metabólitos secundários como forma de proteção. Esses compostos podem ser utilizados na bioprospecção de herbicidas naturais. Dessa forma, objetivamos com este estudo avaliar a fitotoxicidade dos extratos hexânico, acetato etílico e aquoso de folhas jovens de Blepharocalyx salicifolius (Kunth) O. Berg sobre o alongamento de coleóptilos estiolados de Triticum aestivum L. (trigo) e avaliar o potencial fitotóxico do extrato acetato etílico sobre a germinação, crescimento e comprimento das células do metaxilema de Sesamum indicum (gergelim). Os extratos hexânico e acetato etílico inibiram o alongamento dos coleóptilos em todas as concentrações testadas, entretanto os resultados mais promissores foram observados nos fragmentos submetidos ao extrato acetato etílico. Este extrato alterou o tempo médio de germinação e a sincronia das sementes de gergelim, inibiu o crescimento da parte aérea e subterrânea com redução da massa seca das plântulas, levou ao surgimento acentuado de anomalias e causou redução no comprimento médio das células do metaxilema de plântulas de gergelim. Assim, ficou comprovado o potencial fitotóxico dos extratos de folhas jovens de B. salicifolius e a acentuada fitotoxicidade do extrato acetato etílico sobre o desenvolvimento inicial de S. indicum.

Resumo: The present study aimed to screen the Rhazya stricta Decne root for its antihyperglycemic and antioxidants potential through invitro assays along with phytochemical and elemental analyses. The crude extract was prepared through maceration and fractionated using solvent-solvent extraction technique. The spectroscopic studies indicated the presence of various phytochemical classes in the extract and its fractions. The antioxidant assays showed notable results along with a good concentration of phenolic and flavonoid contents. Enzyme inhibition assays demonstrated glucose-lowering effects by inhibiting the enzyme activity which could reduce post-prandial blood glucose level. The Dipeptidyl peptidase-IV (DPP-IV) inhibition assay results showed the novel DPP-IV inhibition activity of the plant extract and all fractions showed noteworthy enzyme inhibition and antihyperglycemic activity. Conclusively, the Rhazya stricta root extract displayed its antioxidant and antihyperglycemic potential due to the presence of various classes of phytochemicals and micro-nutrients.

Título: Micropropagation of Calophyllum brasiliense (Cambess) from nodal segments / Micropropagação de Calophyllum brasiliense (Cambess) a partir de segmentos nodais
Fonte: Braz. j. biol;76(3):656-663tab, graf.
Idioma: en.
Resumo: Abstract Micropropagation of Calophyllum brasiliense Cambess. (Clusiaceae) is a way to overcome difficulties in achieving large-scale plant production, given the recalcitrant nature of the seeds, irregular fructification and absence of natural vegetative propagation of the species. Cultures were established using nodal segments 2 cm in length, obtained from 1-2 year old seedlings, maintained in a greenhouse. Mercury chloride and Plant Preservative Mixture™ were used in the surface sterilizing stage, better results being achieved with Plant Preservative Mixture™ incorporation in culture medium, at any concentration. Polyvinylpyrrolidone, activated charcoal, cysteine, ascorbic acid or citric acid were added to the culture medium to avoid oxidation. After 30 days of culture, polyvinylpirrolidone and ascorbic acid gave better results, eliminating oxidation in most explants. For shoot multiplication, benzylaminopurine was used in concentrations of 4.4 and 8.8 µM in Woody Plant Medium, resulting in an average of 4.43 and 4.68 shoots per explant, respectively, after 90 days. Indole-3-butyric acid and α-naphthalene acetic acid were used to induce root formation, reaching a maximum rooting rate of 24% with 20µM α-naphthalene acetic acid. For acclimatization. the rooted plants were transferred to Plantmax® substrate and cultured in a greenhouse, reaching 79% of survival after 30 days and 60% after one year.

Resumo A micropropagação de Calophyllum brasiliense Cambess. (Clusiaceae) é uma maneira de superar dificuldades para sua produção em larga escala, devido à natureza recalcitrante das sementes, frutificação irregular e ausência de propagação vegetativa natural da espécie. Culturas foram estabelecidas utilizando segmentos nodais com 2 cm de comprimento, obtidos de plantas com 1 a 2 anos de idade, mantidas em casa de vegetação. Cloreto de mercúrio e Plant Preservative Mixture™ foram utilizados durante a etapa de desinfestação, com melhores resultados alcançados com a incorporação de Plant Preservative Mixture™ ao meio de cultura. Polivinilpirrolidona, carvão ativado, cisteína, ácido ascórbico ou ácido cítrico foram adicionados ao meio de cultura para evitar a oxidação dos explantes. Após 30 dias de cultivo, o uso de polivinilpirrolidona ou ácido ascórbico proporcionou melhores resultados, eliminando a oxidação na maioria dos explantes. Para multiplicação das brotações, benzilaminopurina foi usada em concentrações de 4.4 e 8.8 µM em meio WPM, resultando em uma média de 4.43 e 4.68 brotações por explante, respectivamente, após 90 dias. Ácido indol-3-butírico e ácido α-naftaleno acético foram usados para a indução de raízes, alcançando um enraizamento máximo de 24% com o uso de 20µM de ácido α-naftaleno acético. As plantas enraizadas foram transferidas para substrato Plantmax® e cultivadas em casa de vegetação, alcançando 79% de sobrevivência após 30 dias e 60% após um ano.
