Effect of electric field intensity and exposing time on some physiological properties of maize seed

In this research, some physiological properties of maize were investigated as a function of electric field intensity and exposing duration. Maize seeds with initial 28%germination percentage were selected and exposed to electric fields under different time durations. The experiments were conducted with four levels of electric fields (namely, 2, 4, 9 and 14 kv) and four levels of time durations (including 15, 45, 80 and 150 s) in the form of complete randomized block design. After exposing the seeds to electric field, the physiological properties of seeds and seedlings at the first stage of growth were evaluated in terms of seedling dry and wet weight, length of seedling, length of leaf, length of stem, length of root, coefficient of uniformity, germination rate, mean germination time, and germination percentage. At each test, three replications were accomplished and the mean values were calculated. The results revealed that the effects of electric field and exposing time duration on all of the physiological properties of maize were statistically significant
