“…Similar effect of hormesis (adaptive reaction) is observed during many stresses (UV light, heavy metals, herbicides, etc.) and was published by other authors [20,21]. They observed that plants can cope with different stressful conditions to a certain extent (depending of plant species and genotype), after which the ability of defense declines (β-shaped hermetic response).…”

Effects of γ-irradiation on antioxidant activity in soybean seeds

2009

There are some reports that low doses of γ-irradiation could induce antioxidant activities in plant material, including soybean. Irradiation, required for the inactivation of some pathogens and induction of mutations, may have adverse effects on sensorial, nutritional and antioxidant qualities. The effects of different γ-irradiation doses (100-200 Gy) on antioxidant properties of soybean seeds was investigated. In this study, we report the results obtained by analysis of antioxidant enzyme activities, reduced glutathione, malonyldialdehyde (MDA) and hydroxyl (HO˙) radical quantities, soluble protein content, and total antioxidant activity in irradiated soybean seeds. Antioxidant enzyme activities were affected due to high irradiation intensity. Significant changes of total antioxidant activity and MDA and HO˙quantities were observed only under the highest irradiation dose, with a 15.7% reduction in total antioxidant activity, MDA quantity increase of 21.6%, and HO˙ radical quantity increase of 79.3% compared to the non-irradiated control. The total soluble protein content increased slightly.

“…The TSS value of blueberry samples was enhanced post plasma treatment with the highest value of 14.10° brix was found in samples treated at 80 kV for 5 min. might also increase the activity of phenylalanine ammonialyase which would in turn result in increase in phenolic compounds (Stevens, et al, 1996). The increase in the phenolic and flavonoid content of blueberries have also been attributed to depolymerization and dissolution of cell wall polysaccharides, which facilitates higher extraction of the conjugated phenolic compounds (Alothman, Kaur, Fazilah, Bhat, & Karim, 2010;Grzegorzewski, Ehlbeck, Schlüter, Kroh, & Rohn, 2011;Sarangapani, Thirumdas, et al, 2016).…”

“…According to Nigro et al (1998) stored dessert grapes irradiated with UV-C exhibited less fruit rot caused by Botrytis cinerea. Stevens et al (1996; observed the useful effects of UV-C irradiation against fungal pathogens causing rot in various fruit species. Marquenie et al (2002) applied UV-C and heat treatment, and found that Monilinia fructigena reacted more sensitively to these treatments than Botrytis cinerea.…”

The effects of UV-C radiation on the germination rate and fungal contamination of tall fescue seeds were investigated. Samples from the same seed lot were irradiated in two different ways in two consecutive years. The seeds were irradiated with a Hg vapour lamp using different doses. In the first trial one side of the seeds was irradiated, while in the second trial a mirror was used to irradiate the whole seed surface. The results showed that various doses of UV-C irradiation had an effect on the germination rate, but there were no significant differences in germination percentage between the treatments. Differences in fungal contamination rates were observed when the seeds were irradiated on all sides. The presence of 21 fungal genera was identified on the seeds, the saprotrophic fungi Alternaria, Rhizopus and Penicillium being dominant.
