Abstract
Certain growth and metabolic indices of stress induced by visible light and UV radiation in broad bean seedlings. Phyton.(Horn, Austria) 52 (2): 203-218. The effects of either visible light or UV-radiation on growth and metabolism of broad bean (Vicia faba) seedlings were investigated. Exposure of seedlings to low and high visible light and UV-radiation, either alone or in combination, induced variable significant decreases in the levels of growth parameters throughout the experimental period, as compared with values of control seedlings grown in darkness or ambient visible light. In addition, induced pronounced significant changes in the total amount and in the relative composition of pigment fraction contents, associated with significant variable decreases in photosystem II (PSII) activity were observed. In relation to controls, direct exposure of broad bean seedlings to visible light and UV-radiation, induced significant variable changes in the total amount and in the relative composition of the carbohydrate pool. Concurrently with carbohydrate changes, significant variable increases in the activities of both invertase and a-amylase of broad bean seedlings were maintained throughout the entire period of the experiment.
