The effects of zinc on germination, survival and growth of Betula seed
The effects of increasing zinc concentration on germination, survival and growth of birch seed collected from sites showing varying degrees of zinc contamination were investigated. Germination decreased with elevated zinc levels but differences between different seedlots were not found. Distinct differences were found for percentage survival and growth. Radicle elongation was more adversely affected than hypocotyl extension. The nutrient status of the culture media influenced the toxicity of zinc. Tolerance indices at different developmental stages are compared.
