Resumo
Inserir pesquisas e tecnologias nos ramos de sementes nativas da Mata Atlântica é essencial para a pesquisa atualmente. Uma das tecnologias que pode ser aplicada é o uso de biofertilizantes a base de algas que comprovadamente auxiliam no desenvolvimento e crescimento vegetal das plantas sendo uma alternativa ambientalmente segura. Este estudo teve como objetivo a avaliação do potencial de três extratos biofertilizantes sendo esses o Netuno Bio®, o AMPEP (Acadian Marine Plant Extract) e o biofertilizantes Lemgrow, ambos em 3 concentrações diferenciadas, sendo estas de 0% 1% e 2%. O experimento foi conduzido em uma casa de vegetação localizada no Vale do Ribeira. Os produtos foram obtidos diretamente a partir de colaboração já formalizada com as empresas. Foi utilizado o delineamento experimental com três repetições sendo de esquema fatorial em 4x3, totalizando 12 unidades experimentais Ambos em 3 concentrações diferenciadas, sendo estas de 0% (testemunha, sendo apenas solução de água destilada), 1% e 2%. Não existiu a necessidade de quebra de dormência da semente. Em soluções de 100 mL foram preparadas concentrações respectivas de cada produto citado e 100 sementes serão colocadas em cada solução por 16 horas para que houvesse o processo de embebição. Em relação a porcentagem de germinação das sementes a dose da qual melhor apresentou resultados significativos foi a do biofertilizante Netuno Bio® por Netuno Agro em concentração 1% tendo 39% de germinação, 10% a mais do valor de testemunhas, no geral, as doses de biofertilizantes de concentração de 1% demonstraram maior eficácia independente do biofertilizante utilizado. Em relação ao Índice de Velocidade de Germinação foi expressivo o resultado da dose do biofertilizante Lemgrow por Startup Aguagreen em concentração de 1% do qual obteve o melhor número de 57,390 se melhor diferenciando da testemunha (41,090), obtendo o maior sucesso entre os tratamentos. De uma forma geral o biofertilizante de Extrato de Lemna (Lemgrow por Startup Aguagreen) considerando as condições e metodologia neste experimento, apresentou enorme potencial, sendo tão equivalente para as plântulas quanto os produtos de eficácia comprovada já comercializados por indústrias, sendo uma alternativa viável para a utilização agrícola.
Inserting research in the field of native seeds of the Atlantic Forest is currently a focus of research after the development of technologies. One of these technologies that can be applied is the use of algae-based biostimulants, which have been proven to assist in the development and vegetative growth of plants, providing an environmentally safe alternative. This study aimed to evaluate the potential of three biostimulant extracts: Netuno Bio®, AMPEP (Acadian Marine Plant Extract), and the biostimulant Lemgrow - Startup Aguagreen, at three different concentrations: 0%, 1%, and 2%. The experiment was conducted in a greenhouse located in the Vale do Ribeira. The products were obtained directly through a formal collaboration with the companies. The experimental design consisted of three replications in a 4x3 factorial scheme, totaling 12 experimental units. Each concentration was tested at three different levels: 0% (control, using only a distilled water solution), 1%, and 2%. There was no need for seed dormancy breaking. In 100 mL solutions, respective concentrations of each mentioned product were prepared, and 100 seeds were placed in each solution for 16 hours to undergo the imbibition process. Regarding the percentage of seed germination, the concentration of the biostimulant Netuno Bio® by Netuno Agro at 1% showed the most significant results, with a germination rate of 39%, which was 10% higher than the control. In general, biostimulant concentrations of 1% demonstrated higher efficacy, regardless of the biostimulant used. As for the Germination Speed Index, the concentration of 1% of the biostimulant Lemgrow by Startup Aguagreen yielded the highest value of 57.390, which was significantly different from the control (41.090), and achieved the greatest success among the treatments. Overall, the Lemna Extract Biostimulant (Lemgrow by Startup Aguagreen), considering the conditions and methodology in this experiment, showed enormous potential, being equivalent to commercially available products with proven effectiveness in the industry, thus providing a viable alternative for agricultural use.
