Bioinput treatments enhance germination and vigor of Mimosa bimucronata seeds1

ABSTRACT Seed treatment with bioinputs can improve the efficiency of direct seeding by enhancing both its establishment and early growth. This study aimed to evaluate the effects of five commercial bioinputs (Acadian®, Asokop®, AURAS®, Trichodermil® and Stimulate®) on the germination and vigor of maricá [Mimosa bimucronata (DC.) Kuntze] seeds. The germination percentage, germination speed index, mean germination time and primary root and shoot lengths were measured. Asokop® and AURAS® promoted a more uniform germination, whereas Asokop®, AURAS® and Acadian® significantly increased the germination speed. AURAS® also promoted the greatest root development.
