Evaluation of the pelletization effect on lettuce seed vigor (Lactuca sativa L.)

Abstract

Seeds of "Veronica", a crisphead lettuce cultivar (Lactuca sativa L.), were submitted to laboratory tests of humidity, germination, velocity of germination, accelerated aging, cold, electrical conductivity and field emergence. Tests did not show any significant difference of the physiological quality between bare and pelleted seeds, except the accelerated aging. Correlations among laboratory tests and the field emergence were not significant. The field emergence was significantly higher from pelleted seeds than seeds without pellets.
