Resumo
The airing of fungicides, insecticides and growth
regulators through the fi lm coating tomato seed can be promising
in the context of the production of seedlings. However, fi rst there is
a need to understand the dynamics of polymers in the germination
and vigor of seeds. In this way, it was determined the effects of
fi lm coating on the physiological potential of tomato seeds and
seedling growth. To this end, it was used a completely randomized
design in factorial scheme 2x4, being two cultivars (‘Santa
Clara’ and ‘Kada Gigante’) with four concentrations of polymer
I
Disc AG Red L-203 ® (0, 50, 100 and 150mL kg -1 of seed), and
four replications. The interaction among the factors (cultivar x
polymer concentrations) ocurred only for variables germination
and fi rst count. Concentrations 100 and 150mL kg -1 harmed the
germination of seeds of tomato cultivate ‘Santa Clara’. The ‘Kada
Gigante’ cultivar obtained a better performance when compared
to ‘Santa Clara’ regarding the emergence of seedlings. The effect
of fi lm coating on the seeds germination of tomato depends on the
cultivar. The physiological potential of tomato seeds is not changed
by the use of coating polymers.
