Of all environmental factors that influence plant growth and development, light and other regions of the electromagnetic spectrum are most essential. In the present study, the effects of ultraviolet-C (UV-C) irradiation on two cultivars, Victor and Glacis, of pot grown geranium (Pelargonium x hortotum) plants were evaluated. Two-year experimental data showed that low doses of UV-C (i.e. 0.5–5.0 kJ m−2) irradiation led to photomorphogenic changes recorded as increases of fresh and dry weight… CONTINUE READING
