Effect of UV radiation and artificial acid rain on productivity of wheat

Abstract

Responses of physiological parameters to UV irradiation of seeds and acid spraying of plants grown from them have been studied in several wheat species. It has been shown that, in a given species, presowing UV irradiation alone and combined UV and acid treatment generally produce a similar effect. Moreover, they have no significant influence on the yielding capacity of most species and, in some cases, even improve this parameter. All the species studied may be regarded as tolerant of these stress factors.
