“…In contrast, Musil et al (1998) have found that UV radiation slowed seed germination. This depression has increased with increased UV exposure and was most pronounced at shorter UV-B wavelengths.…”

This study was carried out on the effects of different exposures of UV-C irradiation (253.2 nm) (5, 10, 15, 20 and 25 mins) on the mortality of stored product pests: Sitophilus granarius L. (Coleoptera: Curculionidae) as a primary pest, Tribolium castaneum (Herbst) (Col.: Tenebrionidae) and Cryptolestes ferrugineus (Stephens) (Col.: Laemophloeidae) and Oryzaephilus surinamensis (Ganglbauer) (Col.: Silvanidae) as secondary pests. Besides, the viability of treated maize and wheat seed items influenced by UV-C irradiation was analysed by tetrazolium test. Our results confirmed the treatment that leads to total mortality is inversely proportional to the exposure to UV-C radiation. The time of total mortality during the post-treatment period as a function of radiation exposure can be characterised by a power-like trend line for each examined insect species. Our results confirmed the insecticidal efficacy and the sensitivity of pest species with different ecological functions to UV-C irradiation. The primary species in the crop treated by shorter exposure (10 mins of UV-C at a distance of 22 cm) may prevent the introduction of secondary stored product pests enter later. The tetrazolium test showed that the wheat seeds were more sensitive to this physical stress than maize seeds in a similar condition. Values of the recorded viabilities fluctuated highly. The effects of UV radiation on treated wheat and maize seeds are somewhat controversial. However, this pest elimination technique is primarily recommended in environments exempt from viable stored seeds because the intactness of treated seeds cannot be demonstrated.

“…But also, exposure to UV radiation acting on seed coats could improve germination and seedling emergence in many species. Different studies reported that seed irradiation with UV-B radiation promoted the germination of a wide range of species from arid environments (Musil et al, 1998), mesic ecosystems and crop species (Tosserams et al, 1997;van de Staaij, 1994). In those cases, the promotion of germination by UV radiation was attributed to the photodegradation of pericarps by UV-B rays reducing their physical and chemical resistance throughout the facilitation of gas and water penetration from the outside to the embryo and the photochemical modification of pericarp inhibitors inducing dormancy (Beneke et al, 1993).…”

“…Moreover, the exposure of seeds and seedlings to UV radiation in open patches without litter protection could affect emergence processes and seedling growth depending on the intrinsic protection mechanisms of seeds and plants (Musil et al, 1998;Tosserams et al, 1997). There is evidence that long-lived perennial plants with low growth rates, such as evergreen shrubs, have high concentration of secondary compounds in tissues protecting them from herbivore damage, water shortage or exposure to high UV radiation.…”
