Impact of elevated CO2 on mycorrhizal associations and implications for plant growth

摘要: The impact of increasing concentrations atmospheric CO2 upon plant physiology has been widely investigated. Plant, and in particular root, growth is nearly always enhanced as a direct consequence enrichment, with C3 species generally more responsive than C4 species. Such alterations productivity will have for below-ground processes increased carbon allocation to the roots may favour symbiotic relationships. This paper discusses current information available consequences these changes mycorrhizal Generally plants grown under enrichment show phosphorus uptake but nitrogen unaffected. nutrient not correlated colonization roots. Similarly root exudation does increase qualitative differences yet be assessed. However, it predicted that total rhizodeposition materials litter inputs, although mineral biochemical derived inputs occur. such within rhizosphere are discussed future research
