In the present work effect of UV-C radiation was observed on the seed germination and seedling growth of Brassica campestris L. An exposure of B. campestris seeds to enhanced levels of UV-C radiation (05, 10 and 20 minutes) altered the germination and growth pattern. Indeed, high UV-C doses in this experiment (20 min.) determined irreversible growth at morphological levels. The UV-C exposure to dry seeds of B. campestris was found to be stimulatory. The higher doses of UV-C not only increased the seed germination percentage but also root shoot ratio, total length of seedling, seedling vigour index and seedling tolerance index. The R/S of control set was found to be 0.6 in control, 0.9 in dose 05 min., 0.7 in dose 10 min., and 1.1 in dose 20 min. treatment. The total length of the seedling on 5th day was found to be 2.5, 4.0, 3.9 and 4.1cms in control, 05 min., 10 min. and 20 min. respectively. The SVI was found to be 235, 399, 381 and 410 in control, 05 min. 10 min. and 20 min. respectively. The STI values were observed to be 162, 157 and 166 in treatments 05 min., 10 min. and 20 min. respectively.
