Above‐ and belowground biomass allocation in Tibetan grasslands
Journal of Vegetation Science, 2009AbstractQuestion: Optimal partitioning and isometric allocation are two important hypotheses in plant biomass allocation. We tested these two hypotheses at the community level, using field observations from Tibetan grasslands.Location: Qinghai‐Tibetan Plateau, China.Methods: We investigated allocation between above‐ and belowground biomass in alpine

Effect of temperature on biomass allocation in tomato (Lycopersicon esculentum)
Physiologia Plantarum, 1995Temperature may influence dry matter partitioning between fruits and vegetative plant parts either directly or indirectly through its influence on development, flower and/or fruit abortion. The objective of the present work was to investigate whether there is any direct effect of temperature on dry matter partitioning between fruits and vegetative ...

Climate‐driven changes in biomass allocation in pines
Global Change Biology, 2000SummaryFuture increases in air temperature resulting from human activities may increase the water vapour pressure deficit (VPD) of the atmosphere. Understanding the responses of trees to spatial variation in VPD can strengthen our ability to predict how trees will respond to temporal changes in this important variable. Using published values, we tested

Global Allocation Rules for Patterns of Biomass Partitioning in Seed Plants
Science, 2002A general allometric model has been derived to predict intraspecific and interspecific scaling relationships among seed plant leaf, stem, and root biomass. Analysis of a large compendium of standing organ biomass sampled across a broad sampling of taxa inhabiting diverse ecological habitats supports the relations predicted by the model and defines the ...

Biomass and Nutrient Allocation of Tipularia Discolor (Orchidaceae)
Oikos, 1984Tipularia discolor (Orchidaceae) plants were sampled in a deciduous forest in Maryland to determine how biomass and nutrients were allocated to different plant structures during an annual cycle. Corms older than 1 year lose weight gradually during the year and most vegetative growth goes into current year corms.

Effects of fire on sandhill herbs: nutrients, mycorrhizae, and biomass allocation
American Journal of Botany, 1997Differences in growth responses, tissue and soil inorganic nutrients, and mycorrhizal relationships of four herbaceous species were studied on burned and unburned sandhill sites in south‐central Florida, USA. Three species, (Aristida stricta, Liatris tenuifolia var. laevigata, and Pityopsis graminifolia) responded positively to conditions following the

Allocation of Organ Biomass in Perfect and Imperfect Flowers
Annals of Botany, 1993Abstract Perianth MP, gynoecium MG, and androecium MA dry-weight biomass (in g) of 39 species of perfect flowers was measured. These data were pooled with published data from an additional 51 species and used to determine size-dependent variations in (MG and MA) in terms of the hypothesis that the quotient of MG and MA exceeds 1·0 for out-breeding ...
