Carbon dioxide enrichment improves growth, water relations and survival of droughted honey mesquite (Prosopis glandulosa) seedlings.
Low water availability reduces the establishment of the invasive shrub Prosopis on some grasslands. Water deficit survival and traits that may contribute to the postponement or tolerance of plant dehydration were measured on seedlings of P. glandulosa Torr. var. glandulosa (honey mesquite) grown at CO(2) concentrations of 370 (ambient), 710, and 1050 micro mol mol(-1). Because elevated CO(2) de...
متن کاملSeedling Growth of Two Honey Mesquite Varieties Under CO2 Enrichment
Seedlings of 2 varieties of honey mesquite (Prosopis glandulosa var. glandulosa and P. glandulosa var. torreyana) were exposed to 2 concentrations of atmospheric carbon dioxide (CO2) (368 and 704 lmol mol ) in environmentally controlled glasshouses under near-optimal temperature and soil water conditions to determine if CO2 enrichment alters aboveand belowground growth responses. CO2 enrichment...
متن کاملNitrogen Fixation
Plant growth is directly dependent upon an adequate supply of fixed nitrogen. Water and fixed nitrogen are the most common limiting factors for plant growth.There is an abundance of nitrogen in the atmosphere, but it is in the form of the relatively inert gas, N2, and this must be converted chemically or biologically into a more active form before plants can utilize it. Chemical fixation most c...
متن کاملNitrogen fixation in ruminants.
The amount of nitrogen gas (N2) available for microbial protein synthesis via nitrogen fixation in the rumen was estimated. Measurements were made of nitrogen fixation by ruminal ingesta from goats fed low protein rations for a prolonged period of time, and by ingesta from sheep fed high protein rations. Nitrogen fixation by rumen microorganisms incubated for 30 or 180 min in vitro was measured...
متن کاملEctomycorrhizal diversity enhances growth and nitrogen fixation of Acacia mangium seedlings
Increasing interest has been given so far to the role of mycorrhizal symbiosis on plant diversity and ecosystem productivity. However much remains unknown about the effect of ectomycorrhizal fungal diversity on plant growth and rhizobial symbiosis. The purpose of this study is to investigate the influence of ectomycorrhizal diversity on root nodulation and plant nutrient uptake during plant gro...
