SEMENTES DE MARACUJÁ AMARELO INOCULADAS COM BACTÉRIAS SOLUBILIZADORAS DE FOSFATO

Abstract

The passion fruit, a native Brazilian fruit, stands out for its economic and social importance, being widely cultivated on small family farms. In addition to being used as food, it has ornamental and medicinal applications, with high potential in both domestic and international markets. This study aimed to evaluate the effect of different doses of biological inoculant on the quality of yellow passion fruit seeds. The experiment applied different doses of inoculant to passion fruit seeds in a randomized block design with five treatments at concentrations of 0, 10, 15, 20, and 25 mL, each with four repetitions. The variables studied were seedling emergence, emergence speed index, seedling height, number of leaves, dry matter weight, and root length. The product, composed of the bacteria Bacillus megaterium and B. subtilis, did not influence the emergence of yellow passion fruit seedlings but promoted growth in the aerial part, number of leaves, and dry matter weight at doses of 10 to 20 mL. However, higher doses reduced root length, suggesting a possible optimization in nutrient absorption. These results highlight the need for further studies to better understand its effectiveness in different contexts.
