Physiological potential of green bean seeds treated with Bacillus subtilis

Abstract: The association between beneficial microorganisms and green beans can accelerate establishment in the field. objective of this study was to investigate influence seed treatments different doses Bacillus subtilis on physiological potential beans. Seeds from cultivar Macarrão Baixo were used. used a completely randomized design double factorial scheme with factor A treatments: Pelliculation (PC), Drying (PCD), Pre-Imbibition (PI), Biopriming (BP); B, B. subtilis: 0; 7; 14 28 mL commercial product.kg seed-1, control. following applied: moisture content analysis, first count final germination, electrical conductivity, length, fresh dry seedling weight, speed index, emergence. Analysis variance applied data when significant, it compared using Tukey’s test polynomial regression; for absolute control, orthogonal contrast applied, p < 0.05 all analyses. did not impair viability. Vigor benefited use PI 16 20 p.c.kg seed-1. alone had best performance. Biopriming, associated subtilis, favors vigor
