An indicator of the water-use efficiency of C3 plants is their natural abundance of the carbon isotope. When enough water is available, the plants can keep their stomata open, enabling them to use a large pool of carbon dioxide. Thus, they can fractionate more against the heavier 13C, leading to a depletion of the plant material. When less water is available, they need to use more 13C because of the smaller C pool available with the shorter opening times of the stomata. This causes an enrichment of the plant material. We have used this principle to investigate the water-use efficiency of grassland differing in diversity. Sods of grassland with or without forbs were cut and incubated in pots with normal water application or experimental drought. Differences between water treatments were clearly visible in 13C values. However, there were no differences between differently diverse swards. This was probably due to the cutting of the sods, which destroyed deep roots."],["dc.identifier.gro","3148071"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5416"],["dc.language.iso","en"],["dc.notes.status","fcwi"],["dc.notes.submitter","chake"],["dc.publisher","EGF"],["dc.relation.conference","15th European Grassland Federation Symposium"],["dc.relation.crisseries","Grassland Science in Europe"],["dc.relation.eventend","2009-09-09"],["dc.relation.eventlocation","Brno, Czech Republic"],["dc.relation.eventstart","2009-09-07"],["dc.relation.isbn","978-80-86908-15-1"],["dc.relation.ispartof","Alternative Functions of Grassland.
