The aim of this work was to characterize the physiological performance and some of the yield attributes of maize seeds in response to periods of temporary flooding. The study was conducted in an experimental design of randomized blocks, with four treatments composed by four replications, being evaluated the germination, the first count of germination, the germination speed index, the thousand seed weight, the number of seeds per ear, the number of rows per ear, the electrical conductivity in seeds, the length of shoot and primary root and the dry matter of shoot and primary root. Thousand seed weight, number of seeds per ear, number of rows per ear and electrical conductivity in seeds were reduced when plants were exposed to a 72 h flooding period. The flooding period of 72 h adversely affects the growth, the physical characteristics and the vigor of maize seeds.
Key words: Zea mays L., number of seeds, thousand seed weight, electrical conductivity, initial growth.
