WebApr 12, 2010 · Reduction of root metabolic costs permits more carbon resources to be allocated to greater root growth and water acquisition. Reduced root costs may also be beneficial by increasing carbohydrate availability during reproductive growth, since reproduction and roots are competing sinks for current photosynthate. ...

We assessed effects of natural seasonal drying, and a rainfall reduction experiment, on soil CO 2 fluxes (i.e., carbon losses via respiration) from four distinct tropical forests in Panama.
Webcontrol of C acquisition by roots (Farrar and Jones 2000). We concluded that each of the fluxes that contributes to the net acquisition of C exerts some degree of control over the … WebWe review four hypotheses for the control of carbon acquisition by roots, and conclude that the functional equilibrium hypothesis can offer a good description of C acquisition by roots relative to shoots, but is deficient mechanistically. The hypothesis that import into roots is solely dependent on export from the shoot, itself determined by ...
