“…Other studies demonstrated that a UV‐C dose of 34.5 kJ m −2 was effective in reducing soft rot caused by Pectobacterium carotovorum subsp. carotovorum in infected potato tubers (Rocha et al ., ). The present study found that 57.6 kJ m −2 reduced incidence by around 90% on artificially and 91% on naturally infected seed, and in most cases 86.4 kJ m −2 reduced infection to an undetectable level.…”

“…Among these, UV-C radiation is used as an effective biocide agent against microorganisms in water, on surfaces and in air (Chevrefils et al, 2006). Furthermore, several studies have demonstrated that UV-C radiation is an alternative treatment for reducing postharvest bacterial infections and promotes synthesis of antioxidant molecules (Rocha et al, 2015). The effectiveness of UV-C treatment has been successfully applied to reduce root infections of groundnut, mung bean (Siddiqui et al, 2011;Neelamegam & Sutha, 2015), tall fescue (Varga & Nagy, 2008) and cabbage (Brown et al, 2001) seeds.…”

The potential of UV‐C radiation of Andean lupin (Lupinus mutabilis) seeds to eradicate seedborne infections of anthracnose caused by Colletotrichum acutatum was investigated. UV‐C doses from 0 to 691.2 kJ m−2 (resulting from 0 to 96 h of exposure time) on disease incidence reduction and germination on artificially and naturally infected seed were evaluated. The degree of incidence reduction and seed germination was dependent on the dose of UV‐C. The UV‐C doses of 86.4 kJ m−2 and higher reduced incidence from 6% to 7% to undetectable levels, but these UV‐C doses also reduced seed germination. UV‐C can deleteriously affect physiological processes and overall growth. To assess its impact, L. mutabilis seeds irradiated with UV‐C doses of 57.6 and 86.4 kJ m−2 were grown. Seedlings grown from noninfected seed and UV‐C treated seed showed an increased concentration of chlorophyll and protein contents, as well as an increase in the activation of defence enzymes peroxidase and catalase, in comparison with plants grown from infected seed. UV‐C doses resulted in seed emergence and seedling dry weight rates that were similar to the noninfected control or better than the fungicide control. Moreover, 57.6 kJ m−2 reduced transmission of the pathogen from seed to the plantlets by 80%, while 86.4 kJ m−2 apparently eradicated the pathogen, under greenhouse conditions. The use of UV‐C, first reported here, is advantageous for controlling anthracnose in lupin.

“…In general, the use of UV-C is beneficial in treatments against bacteria, fungi, and diseases, occurring during storage of crops and foods. For instance, the UV-C radiation and fluorescent light was useful to control postharvest soft rot in potato seed tubers [32].…”

Alpinia zerumbet (Pers.) B.L. Burtt. & R.M. Sm is an important perennial ginger plant in the tropics with various uses as foods, dietary supplement, cosmetics, essential oil production and traditional medicines. In this study, essential oils, phenolic acids, fatty acids, kavains, total phenols and antioxidant activity in A. zerumbet plants exposed to UV-C were investigated. Number and weights of essential oils increased rapidly from 1 to 3 days of exposure. Major extend of essential oils was recorded in methyl cinnamate and followed by benzyl acetone. The correspondence to the accumulation of palmitic acid was 15 folds, in contrast to the strong reduction of stearic quantity was 10 folds at 3 days of treatment. Changes in chemical components and antioxidant capacity in A. zerumbet are differed reversely between the exposure of UV-C and heavy toxic chemicals. The exposure of UV-C is beneficial for the increasing of essential oil production in A. zerumbet.

“…However, different results have been reported in other species, showing, for example, that the use of UV-C and fluorescent light are advantageous for controlling soft rot in potato plants without adversely affecting sprouting [49]. Seed treatments with low doses of UV-C (3.6 kJ/m 2 /day) were used to elicit host resistance to black rot in cabbage (Brassica oleracea L.), improving the quality and growth response of cabbages under greenhouse conditions [19].…”

Light is the only key factor essential for plant growth, and ultraviolet (UV) rays, the harmful part of solar radiation, have the ability to decrease the metabolic rate in photosynthesis, causing deterioration in their growth. Accurate handling of the ultraviolet light that reaches the crops allows the improvement of different aspects of production, such as the shape and color of the plants, the precocity of the crops, and an improvement in the control of pests and diseases. The present study was carried out with the purpose of studying the responses in terms of germination and growth of four plant species—Glycine max, Triticum aestivum, Helianthus annuus, and Pinus maximartinezii—exposed to different doses of UV-C and UV-B radiation, for evaluation through the standard germination and accelerated aging tests, registering the germination rate (GR) and vigor (V), the number of normal seedlings (NS), and the average lengths of radicle (ALR) and plumule (ALP). Seeds treated with UV-C radiation showed a significant difference (p <0.05) between treatments (doses) and species, both in the standard germination and accelerated aging tests for the ALR and ALP variables. Seeds of G. max showed low sensitivity in both tests, with the dose 43.20 kJ/m2/day. The seeds of H. annuus and P. maximartinezii showed high sensitivity in both tests under UV-C radiation, with the doses 8.64 kJ/m2/day and 0.864 kJ/m2/day, respectively. Both tests under UV-B radiation showed a significant difference (p < 0.01) between species and treatments in the variables NS and ALP, with the minimum dose (T2).
