| Abstract | ||||
| The effects of heat, UV-irradiation and salinity on growth and metabolism of broad bean plants were investigated. Exposure of bean plants to these stressful factors induced variable significant decreases in the levels of growth parameters throughout the experimental period, as compared with control plants. In relation to controls, direct exposure of broad bean plants to heat, UV-irradiation and salinity stresses, induced significant variable changes in the soluble carbohydrate components. Concurrently with carbohydrate changes, significant variable increases in the activities of both invertase and α-amylase of broad bean plants were maintained throughout the entire period of the experiment. | ||||
