Variations in progeny of Vicia faba plants differently affected by cobalt

Abstract

Co2+ excess in Vicia faba induced not only chlorophyll morphoses in M1, but also significanlty increased pigmentation variations in M2. The effect depended on plant injury extent expressed by chlorophyll morphosis phenotypes in M1. Superoxide dismutase (SOD) isozyme investigation showed that new types of SOD profiles arose among M2 altered plants. This observation was associated mainly with FeSOD. The observed phenomena need futher investigations. Keywords: Co-stress, variation in M2 generation, chlorophyll morphoses, SOD polymorphism
