Abstract

The sunlight wavelengths between 100 nm and 400 nm are called UV radiation including UV-A (320-390nm), UV-B (280-320 nm) and UV-C (100-280 nm). It is well documented that stratospheric ozone absorbs most of these harmful radiations. However, stratosphere depletion due to human activities has led to UV-B radiation increase on earth. In line with that, this study was carried out to evaluate the Effects of UV-B Radiation on Germination and Seedling Growth of Five Cultivars of Sugar Beet (Beta vulgaris). For this purpose, sugar beet seeds were exposed to UV-B (12 kjm-2d-1) while germination and during developing of seedlings. Results showed that seed germination is not affected by UV radiation, however, seedlings growth in all five cultivars (Ic, Jaam, 7233, Br1 and Sbsi-007) was declined significantly under UV-B radiation. Moreover, UV-B radiation resulted in disfigured seedlings production.
