Resumo
Carrot crop has a great economic importance in Brazil. This crop does not show an
adequate number of plants in its final stand, it is due to low uniformity of the size of seeds. The
quality of a seed lot is also determined by their size. The aim this work was to evaluate the in‐
fluence of the carrot seeds size in vigor, the dry matter accumulation, the productivity and the
market classification. Evaluations used were: first count of germination (vigor test); dry matter
of roots; productivity; and production, based in the market classification required. Experiment
was carried out in randomized block design, with four treatments represented by different sizes
(T 1 : 1.6 to 1.8 mm, T 2 : 1.81 to 2.0 mm, T 3 : 2.01 to 2.2 mm and T 4 : 2.21 to 2.4 mm) and four replica‐
tions. The T 2 treatment showed greatest mean of germination percentage, in the first count.
However there were no significantly statistical differences to the other variables. Thus, the
seeds size neither has influence on the physiological potential of carrot seeds nor increase its
productivity.
