The data had been compared through the test of Tukey with the level of 5% of probability. The used statistical program was the ASSISTAT, developed for Dr. professor Francisco de Assis of the Department of Agricultural Engineering of the Center of Technology and Natural resources of the Federal University of Campina Grande (UFCG), Paraba (HISSES & AZEVEDO, 2006). Gerbox had been divided two stages observing the germination of seeds in boxes and through paper germitest. Germination in boxes gerbox. 400 seeds had been used, being four repetitions totalizing in 80 seeds for each treatment.

The treatments had been: 1) fluorescent light white continuum; 2) dark continuous; 3) blue color; 4) red color and 5) yellow color. For each treatment four boxes had been used gerbox measuring (10 x 10 cm), contend each one of them 20 seeds of maize and having as substratum two humidified sheets of paper germitest and with 10 mL of distilled water esterilizada (ADE). For attainment of the colors the boxes gerbox had been coated with corresponding paper cellophane to each treatment. The dark one was gotten involving the boxes gerbox with paper aluminum. All the set was incubado in estande of steel with two white florescentes lights (40 w), approximately 200 lux, to a distance of 30 cm of the boxes gerbox, under for a period of seven days. The evaluation consisted of making the reading of the number of germinated seeds, length of the aerial part and root (BRAZIL, 1992). Germination in paper germitest Had used 400 seeds, being 80 for each treatment. The treatments had been: 1) fluorescent light white continuum; 2) dark continuous; 3) blue color; 4) red color and 5) yellow color. In each treatment three leves had been used of paper germitest measuring 60 x 60 cm, previously esterilizadas in greenhouse 160oC, perfazendo the total of 20 coils, I contend each one of them 20 seeds of maize.
