“…The importance of a shift in the partitioning of recently assimilated carbon and nutrients to leaves, stems and roots in relation to growth and productivity is also widely acknowledged (Jackson, 1993;Thornley, 1995;Van der Werf et al, 1993;Wilson, 1988). Already in the twenties of this century it was recognised that shoots and roots act interdependently (Crist and Stout, 1929;Turner, 1922). Approximately 40 years later, Brouwer (1962Brouwer ( , 1963 introduced the concept of the "functional equilibrium".…”

“…The most important biotic factors are the innate patterns of C allocation of the plant species and degree of competitiveness in the environment (Hunt and Lloyd 1987;Farrar 1992;Wilson and Tilman 1995), while abiotic factors that affect C allocation include resource availability and environmental stresses (Norby 1994;Ericsson 1995;Poorter and Nagel 2000;BassiriRad et al 2001;Luo et al 2006;Maestre and Reynolds 2006). Plant shoots and roots, although complementary and interdependent, do not respond to environmental changes at the same rate or by the same magnitude (Crist and Stout 1929;Brouwer 1962;Brouwer 1983). Among the many global changes projected for the future, the most prominent and best documented is the gradual but steady rise of CO 2 concentration in the atmosphere (Keeling et al 1995;IPCC 2007).…”

“…Effects of an environmental change such as elevated CO 2 on biomass allocation may be obscured due to additional factors that influence shoot and root production. For example, biomass allocation has been found to depend on the innate growth potentials of the species (Crist and Stout 1929;Hunt and Nicholls 1986;, the ontogenetic stages when plants were harvested for biomass measurement (Wilson 1988;Eamus and Jarvis 1989;Shipley and Meziane 2002) and different experimental protocols that have been used in the numerous CO 2 studies (Ericsson 1995;BassiriRad et al 2001). To further complicate the assessment of the interaction of CO 2 and other factors, quantification of fertility and water in the soil used for growing plants is mostly relative.…”

Rising atmospheric CO(2) greatly enhances plant production, but its effect on biomass allocation, particularly in the presence of environmental stresses, is not well understood. Here, we used meta-analysis combined with pairwise techniques to examine root mass fraction (RMF; i.e., the fraction of root to total biomass) as affected by elevated CO(2) and environmental stresses. Our results showed that lower soil fertility increased RMF and the magnitude was similar for ambient and elevated CO(2)-grown plants. Lower soil water also increased RMF, but to a greater extent at elevated than at ambient CO(2). While CO(2) enrichment had little effect on the magnitude of O(3)-caused reduction in RMF in herbaceous species, it alleviated the adverse effect of higher O(3) on root production in woody species. These results demonstrate that CO(2) has less pronounced effects on RMF than other environmental factors. Under abiotic stresses, e.g., drought and higher O(3), elevated CO(2)-grown plants will likely increase biomass allocation below-ground. Because of the non-uniform changes in drought and O(3) projected for different parts of the world, we conclude that elevated CO(2) will have regional, but not global, effects on biomass allocation under various global change scenarios.

Innate growth potential and innate patterns of allocation to different plant parts are both subject to physiological limitations. Yet the ways in which these attributes not only vary between species but also exhibit plasticity in response to environmental change are important determinants of ecological behaviour and contribute strands to Plant Strategy Theory. In this paper, we review the evidence for innate variation in growth potential and partitioning and consider the implications of this variation for the development of high-level ecological syntheses.
