Abstract
The present study was aimed to investigate the effect of different ultraviolet radiation doses on the growth, and antioxidant enzymes of three cultivars of soybean ( Glycine max L.) (‘Giza-22’, ‘Giza-35’ and ‘Giza-111’). The seeds were grown in plastic pots equally filled with a mixture of pre-sieved sandy loam soil, peat-moss and vermiculite (2: 1: 1) for two weeks. The planted pots were divided into four groups and exposed to white light (1,100 Lux) (control), 3.2, 6.4 and 12.8 KJ m −2 d −1 UV A+B radiation, respectively, for 30 days and then harvested. The results indicated that shoot dry weight was decreased with increasing UV A+B radiation doses; it was found that supplementation of UV A+B radiation increased root dry weight in all studied cultivars of soybean plants. With referring to oxidative stress, it was found that increasing UV radiation induced significant increases in H 2 O 2 concentration, lipid peroxidation and cell death (as ion leakage) in soybean cultivars. Increasing supplemental doses of ultraviolet radiations significantly induced reductions in all studied antioxidants (catalase, peroxidase and superoxide dismutase (SOD) activities and glutathione content).
