Contrasting allocation patterns in wheat and weeds: allometric belowground and reproductive investment versus optimal partitioning adaptations [PDF]
IntroductionModeling differences in biomass allocation between wheat and weeds—specifically to shoots (aboveground biomass), roots (belowground biomass), and seed mass (reproductive biomass)—enhances our understanding of sustainable weeds management ...

Consistency between an allometric approach and optimal partitioning theory in global patterns of plant biomass allocation [PDF]
Summary Optimal partitioning theory (OPT) suggests that plants should allocate biomass to the organ that acquires the most limiting resource. An implied assumption of this is that there are trade‐offs in allocation between leaf, stem and root functions.

Trade-Offs and Partitioning Strategy of Carbon Source-Sink During Fruit Development of Camellia oleifera [PDF]
Non-structural carbohydrates (NSCs), the main substrates and energy carriers of plants, play an important role in mediating the source-sink balance of carbon (C).

Biomass allocation between reproductive and vegetative organs of Artemisia along a large environmental gradient [PDF]
Background Biomass allocation reflects functional tradeoffs among plant organs and thus represents life history strategies. However, little is known about the patterns and drivers of biomass allocation between reproductive and vegetative organs along ...

Shrubland biomass and root-shoot allocation along a climate gradient in China [PDF]
Background – Shrublands are receiving increasing attention because of climate change. However, knowledge about biomass allocation of shrublands at the community level and how this is regulated by climate is of limited availability but critical for ...

Different biomass allocation strategies of geophytes and non-geophytes along an altitude gradient
Biomass allocation strategies among geophytes and non-geophytes generally determine the ecological adaptation and impacts of herbaceous plants. Although geophytes and non-geophytes are key components of the biodiversity of subtropical forest ecosystems ...

Changes in Root–Shoot Allometric Relations in Alpine Norway Spruce Trees After Strip Cutting
Silvicultural interventions such as strip cuttings can change the resource availability of the edge trees. This may alter tree allometry, as light regime, water, and nutrient availability can change at the forest edge.

Water Stress Scatters Nitrogen Dilution Curves in Wheat
Nitrogen dilution curves relate a crop’s critical nitrogen concentration (%Nc) to biomass (W) according to the allometric model %Nc = a W-b. This model has a strong theoretical foundation, and parameters a and b show little variation for well-watered ...

Above- and Belowground Biomass Allocation in Shrub Biomes across the Northeast Tibetan Plateau.
Biomass partitioning has been explored across various biomes. However, the strategies of allocation in plants still remain contentious. This study investigated allocation patterns of above- and belowground biomass at the community level, using biomass ...

Biomass Allocation of Invasive Cenchrus pauciflorus Based on R Package Smatr
Elucidating patterns of plant biomass allocation is an important subject in ecological research. Broadly speaking, two schools of thought are applied to understand it: allometric partitioning theory (APT) and optimal partitioning theory (OPT).
