Increased incident ultraviolet (UV) radiation due to ozone depletion has heightened interest in plant responses to UV because solar UV wavelengths, particularly UV-8 (280-320 nm) can affect plant growth, and productivity. Where crops are grown in protected environments such as glasshouses and polytunnels, there is now significant scope to exploit the fundamental light responses by manipulating the light environment reaching the crop. The recent advances in polymer chemistry and manufacturing methods have produced a range of novel films that selectively filter specific radiation wavelengths, and so provide the opportunity to exploit plant light responses for crop production. This project aimed to study the effects of UV manipulating crop covers on aspects of yield and quality of crops of economic importance to the Egyptian horticultural industry. The project focuses also on the understanding of the mechanism of plant responses to manipulating UV-8 radiation in controlled environment conditions at Lancaster University in terms of the cell expansion and cell division as well as photosynthesis of carbon fixation. Crops used in this PhD project were sweet pepper (Capsicum annuum) and lettuce (Lactuca sativa). Most of the findings of these studies are applied in the horticultural cultivation. The novelty of the results here is that exploiting plant exposure to UV-8 radiation to improve the long-term performance of growth and increase yield of fruit crop under high standard of commercial practice and to understand the mechanism(s) which responsible for such plant responses.
