Test germination of corn seeds in different environments

The germination test aims to determine the maximum potential of germination of the seed lot and estimate the value of sowing in the field. The objective of this study is to assess the germination of maize seeds in different types of germination environments. The experiment was conducted in a completely randomized design, factorial scheme (3 x 2) with eight replicates. For the development of this experiment, the maize seeds were subjected to three environments (treatments) which were used in the germination test: BOD germinator, Thermal Seed Germinator and mini plastic tray. Tests were installed with eight replications of 50 seeds per lot, at a temperature of 25 degrees C. The counting of seeds subjected to the environments was held at four days and seven days after sowing. It was evaluated the characteristics: normal and abnormal seeds. It was observed that the different environments provided significant differences in the germination test of maize seeds. Through the results of the germination test at 4 and 7 days of counting, there was significant difference between the environments, being that the treatment carried out in BOD incubator had a higher germination percentage in relation to the other two treatments, with a percentage of 90,25%. It was verified that the best environment for conducting germination of maize seeds is in the BOD germinator.
