摘要: ABSTRACTCopper (Cu2+) is an essential nutrient for plants but toxic at high concentrations. We subjected seedlings and young of eelgrass Zostera marina to different seawater Cu concentrations (3, 4, 5, 10, 30 50 µg l−1) over days under controlled laboratory conditions. Natural without added (3 µg l−1) was used as reference seawater. measured plant response in terms survivorship, morphology, growth, productivity leaf pigment concentration. Survival analysis combined with morphological, dynamic productive assessment suggested that the optimum concentration establishment Z. 4 μg l−1. The photosynthetic copper enrichment, including increase chlorophyll content low treatment significant decrease when treated Cu, similar those reported other seagrass species. NOEC (no observed effect concentration), LOEC (lowest...
