Heavy Metal Allocation to Pea Plant Organs (Pisum sativum L.) from Soil during Different Development Stages and Years

The incorporation of heavy metals contained in soils into the food chain is mediated by plants. Plants show varying abilities to take up and accumulate these elements during vegetative growth. In this study, changes content, rate uptake, accumulation, translocation six stages development pea plants were determined. field experiments, two cultivars cultivated consecutive growing seasons. harvested divided roots aerial parts, at full maturity seeds separated additionally. Significant content parts on average entire plant, as well their bioaccumulation factors (BAFs), most often noted flowering stage plants, after which values usually did not change significantly. highest uptake per day growth was between when 50% pods typical length. Their factor (TF) three-internode stage. BAF, TF varied years but significantly depend cultivar. BAF indicates potential hyperaccumulate lead zinc moderate accumulation other parts. Excessive concentrations cadmium disqualified pea’s be used human food, whereas excessive prevented use fodder. Green mass can animal fodder according EU directives.
