Physiological quality of creole corn seeds produced in Oeste Potiguar

Abstract

The evaluation of seed quality through germination and vigor tests represents an important aid for farmers, in order to select the best quality lots. Thus, the objective was to classify classify and evaluate the physiological quality of corn creole seeds (Zea mays L.) through the germination test and first count (vigor). Fifteen batches of creole corn were purchased in rural communities distributed in seven regions of Oeste Potiguar in the state of RN. The experimental design was completely randomized, with eight replications of 50 seeds. The germination test was installed on towel paper, moistened with distilled and literal water in a germination chamber at 30 ° C with a 12-hour photoperiod. The first count was performed on the fourth day after sowing and the percentage of germination on the seventh day counting the percentage of normal seedlings. Most of the existing lots have physiological quality.
