Abstract: Number of seed treatments methods are available now days for improving germination and increasing vigor of seedling. Seed invigoration means treating seed before sowing and before storage to get healthy seedlings under favorable and unfavorable condition. There are many types of seed invigoration for seeds but some are rarely used by farmer group to treat the seeds. Physical seed invigoration is recent advances in seed technology for seed treatment Use of radiations for treating plants is adapted from many past years but only few studies reported in seed technology. UV radiations are responsible for causing mutations in living organism present on earth. It was found that the seeds exposed to the UV radiations for longer duration showed marked effect on the germination percent and the probable reason found for the behavior was due to breaking of seed coat, increase in internal temperature of seed. On the part of health seeds behaved in more potent way in tackling the diseases. Probable reason for such kind of behavior may be the mutation in genome of the individual plant seed.
