“…Figure 1. Number of leaves of yellow passion fruit, produced with microalgae biomass at different doses of application, at 60 days after sowing Silva et al (2015) observed in Annona glabra seedlings that the largest leaf numbers were obtained with the 2.0 ml/L dose of Ascophyllum nodosum extract, and the use of larger doses showed a reduction in the expression of the growth variables evaluated. Authors associate the reduction of the phytotechnical characteristics to the condition of saline stress caused by the solutions when applied in higher doses.…”

“…These microalgae present important nutrients essential for the plant growth (nitrogen, phosphorus and potassium), favoring the accumulation of phytomass through the use of mineral nutrients by the plants and improving soil structure and aeration, stimulating the growth of the root system (Calvo et al, 2014;Marich et al, 2014). According to Silva et al (2015), studying the application of Ascophyllum nodosum seaweed extracts in the production of araticum-do-brejo rootstocks, the use of doses above 4 ml/L negatively influences the vegetative growth of the plants, due to the solutions.…”

Seedlings production is one of the most important stages of the production system and directly influences the performance of the plant in the field. In this sense, the present work aims to evaluate the use of biomass doses of Spirulina platensis and Scenedesmus sp. via root system on the production of yellow passion fruit seedlings. A greenhouse experiment was carried out using a randomized block design in a 2 × 5 factorial scheme (Spirulina platensis and Scenedesmus sp., at the doses 0.0%, 0.2%, 0.4%, 0.8 % and 1% m/v), with four blocks and two experimental units per plot. At 60 days, leaf number, total seedling length, shoot diameter, root system length, shoot length, shoot and root fresh mass, dry mass, root dry mass and total chlorophyll were measured. Spirulina platensis showed superior performance compared to Scenedesmus sp., for the variables stem diameter, shoot length, fresh shoot mass, fresh root mass, dry shoot mass and root dry mass. The doses influenced the number of leaves, root fresh mass, root dry mass, shoot length and fresh shoot mass significantly. The best dose of microalga applied was 0.8% in passion fruit seedlings at 60 days.

Aims: Evaluate the effects of applying biostimulant and micronutrients on Acacia mangium Willd seedlings. Study Design: A randomized complete block design was used in a 2x5 factorial scheme, with four replications. Place and Duration of Study: The experiment was conducted at the Universidade Federal de Mato Grosso do Sul, at the Chapadão do Sul Campus, MS, with the geographical coordinates 18º46’ 44” S and 52º36’ 49” W, in a nursery area from October 2015 to January 2016. Methodology: The treatments consisted of a combination of the presence or absence of a solution containing micronutrients and five doses of biostimulant (0, 7.5, 15.0, 22.5, and 30.0 mL per L of water). The commercial product Stimulate™ was used as the biostimulant, and the micronutrient solution was prepared at the concentration of 1.0%. The micronutrients in the solution were in the following formulations: ZnS04, H3BO3 and CuS04. The seeds were sown in tubes containing the commercial substrate Carolina Soil do Brasil, together with the use of Osmocote Plus™ fertilizer. Results: The use of biostimulant associated with micronutrients favored the rate of emergency speed. The doses of 24.8, 14.0 and 26.1 mL L-1 of biostimulant water provided the highest values for leaf area, plant height and total dry mass, respectively, when associated with the use of micronutrients. The height / diameter ratio decreased with increasing doses of biostimulant, while the Dicson quality index increased in the same condition. Conclusion: The use of micronutrients and biostimulants were favourable for the production of A. mangium seedlings. Only the height/diameter ratio (HDR) reduced for all biostimulant doses.

“…Silva et al (2016) observaram em mudas de Annona glabra, que para o número de folhas e matéria seca da parte aérea os melhores resultados foram obtidos com a dose de 2,0 mL L -1 H2O do extrato de Ascophyllum nodosum, doses maiores apresentaram redução na expressão das variáveis. Os autores associam a redução das características fitotécnicas à condição de estresse salino causada pelas doses superiores.…”

“…Entretanto, Silva et al (2012) De modo geral, no presente estudo a aplicação da dose 0,75 mL planta -1 apresentou melhor desempenho, e conforme o aumento de dose constatou-se redução na expressão fisiológica para as diferentes variáveis. Resultados semelhantes foram encontrados em experimentos com amora-preta e feijão-da-china (KAVIPRIYA et al, 2011;DIAS et al, 2012), em que ao testar diferentes doses de bioestimulantes, foi identificado a existência de uma dose máxima para ganho de crescimento das plantas e que doses superiores a esta causaram prejuízo ao desenvolvimento das espécies.…”

Resumo -A produção de mudas com qualidade é fundamental na exploração das culturas agrícolas, e os bioestimulantes apresentam-se como ferramentas benéficas nessa fase da planta. O estudo objetivou avaliar as diferentes concentrações de bioestimulante composto por extrato de algas, no favorecimento da expansão radicular e desenvolvimento vegetativo inicial de mudas de uva, cultivar Crimson Seedless enxertadas em porta-enxerto SO4. O experimento foi realizado em viveiro comercial na cidade de Petrolina-PE. O delineamento experimental utilizado foi o inteiramente casualizado, com cinco tratamentos e quatro repetições. Os tratamentos foram: (T1) 0; (T2) 0,75; (T3) 1,12; (T4) 1,5 e (T5) 1,87 mL planta -1 do bioestimulante. Aos 45 dias após a enxertia foram analisados o comprimento e diâmetro da brotação do enxerto; área foliar; diâmetro, densidade, área, comprimento e matéria seca das raízes e matéria seca da parte aérea. Os dados foram submetidos à análise de variância e análise de regressão polinomial. Os melhores resultados foram proporcionados pela aplicação da dose 0,75 mL planta -1 . O aumento da dose causou redução na expressão das variáveis. Conclui-se que o bioestimulante é uma ferramenta importante na produção de mudas com qualidade.

The study aimed to evaluate the different concentrations of biostimulant containing algae extract on root expansion and initial vegetative development of grape seedlings cv. Crimson Seedless grafted on SO4 rootstock. The experiment was conducted in commercial nursery in Petrolina county, Pernambuco state, Brazil. The experimental design used was the completely randomized design, with five treatments and four replicates. The treatments were: (T1) 0; (T2) 0.75; (T3) 1.12; (T4) 1.5 and (T5) 1.87 mL plant -1 of the biostimulant. At 45 days after grafting the length and diameter of the graft sprouting; leaf area; diameter, density, area, length, and dry weight of roots and shoots were analyzed. The data were subjected to analysis of variance and polynomial regression. The best results were provided by 0.75 mL plant -1 biostimulant dose. Increasing biostimulant doses caused the reduction of variables expression. It is concluded that the biostimulant is an important tool for production of quality grape seedlings.
