ABSTRACT:

The time of exposure and mutagenesis effects of X-raJ on the germination, growth and development of maize (Zea mays) seeds have been investigated employing a nuclear source, (Sr as X-ray source; 3mA, 70kv). Five sects of zea mays seeds in different packs were irradiated in different times of exposure and later planted separately with another 61h non-irradiated  sects (control experiment) on an open fertile land. Measurements at eight days interval were carried out on the plants' heights, its leaves widths, days to another and silk for six consecutive times after planting. Results revealed, the day to anther (42) days and day to silk (35) days after planting respectively for the irradiated sects were delayed. A comparative study carried out on all the sects in terms of the plants' height and leaves' width indicated that 83 percent of the plants examined showing consistent mutation in both heights and leaves width as a function of time of exposure.
