Sexual reproduction traits of Holcus lanatus L. and Parnassia palustris L. in response to absolute and relative supply of nitrogen and phosphorus

摘要

Plant investment in sexual reproduction is affected by absolute and relative nitrogen (N) and phosphorus (P) supply. Reduced investment in reproductive traits has been suggested as an important adaptation to strong P-limitation. We experimentally tested how absolute and relative nutrient supply affected sexual reproduction traits of two grassland species.
