AB Seed germination and seedling establishment are the stages most sensitive to abiotic stress in the plant life cycle.We analyzed the effects of copper, zinc and nickel on seed germination and early seedling growth of nativeSpartina maritima and invasive S. densiflora from polluted and non-polluted estuaries. Germination percentagesfor either species were not affected by any metal at any tested concentration (up to 2000 μM). However, theincrease in metal concentration had negative effects on S. densiflora seedlings. The primary effect was on radicledevelopment, representing initial seedling emergence. Spartina densiflora seedlings emerging from seeds fromTinto Estuary, characterized by high bioavailable metal loads, showed higher tolerance to metals than thosefrom less polluted Odiel and Piedras Estuaries. Comparing our results to metal concentrations in the field, weexpect S. densiflora seedling development would be negatively impacted in the most metal-polluted areas inOdiel and Tinto Estuaries.
