Abstract


The aim of this study was to assess the effect of seed treatment at different levels of physiological quality
with amino acids on the performance of seeds and plants in the field. The experimental design was a randomized complete
block design with four replications involving a combination of two factors. Factor A consisted of seed lots of three levels of
physiological quality (high, intermediate, and low) and factor B consisted of five doses of a commercial product based on
amino acids used in seed treatment.Seeds of different levels of physiological quality were treated with a commercial product
(C.P.) at doses of 0, 200, 400, 600, and 800 mL C.P. 100 kg−1 of seeds. After seed treatment, the physiological performance was
assessed in the laboratory and then the seeds were sowed in the field aiming at assessing plant performance, yield components,
and productivity. Seed treatment with amino acids does not promote the physiological performance of seeds and plants in the
field. The productivity of isolated soybean plants from seed lots of a high physiological quality is 15% higher than that of
plants from seed lots of a low physiological quality.
