Resumo

The objective of this work was to evaluate seed germination and the initial development of soybean plants with low physiological quality seeds submitted to different doses of phytoregulator. The experiment was carried out from March to April 2018 in Campo Novo do Parecis, MT, Brazil. The experimental design was of completely randomized blocks, in a 3x4 factorial scheme, being three soybean cultivars: Monsoy 7739, Desafio and Monsoy 8372, and four doses of phytoregulator: 0.0; 0.5; 0.75 and 1.0 L ha-1 of Stimulate® composed of cytokinin, indole butyl acid and giberelic acid. Totaling 12 treatments with four replicates. The evaluated variables were: initial germination, final germination, plant height, dry shoot mass, dry root mass and total dry mass. The cultivars responded differently to the phytoregulator doses. The cultivar Monsoy 7739 responded positively to the use of phytoregulator, as it increased germination, presented higher plant height, dry root mass and total dry mass, at the maximum dose of 1.0 L ha-1.The cultivar Desafio responded negatively to the phytoregulator, as germination presented significant differences compared the other evaluated variables. Monsoy 8372 did not conclusively respond to the use of the phytoregulator conclusively.
