Biomass and Carbon Partitioning in Switchgrass

Crop Science, 2004
Grasslands have an underground biomass component that serves as a carbon (C) storage sink. Switchgrass (Panicum virgatum L.) has potential as a biofuel crop. Our objectives were to determine biomass and C partitioning in aboveground and belowground plant components and changes in soil organic C in switchgrass.

Simulation of Biomass Partitioning and Production in Elephantgrass

Communications in Soil Science and Plant Analysis, 2006
Abstract The expanded growth model has been used to simulate biomass accumulation with time by elephantgrass (Pennisetum purpureum Schum.) grown in Florida. It has been used to describe partitioning of biomass between stem and leaf components of the plant as well as total biomass accumulation with time.

Modelling optimal plant biomass partitioning

Ecological Modelling, 1994
Abstract A theoretical framework is presented to quantitatively describe the dynamics of biomass partitioning in plants. The approach is based on the assumption that nitrogen supply is limiting plant growth, and hence the nitrogen concentration of leaves is adjusted in such a way that the relative growth rate of the plant is maximized.

Modeling of biomasse acquisition and partitioning in the architecture of sunflower [PDF]

, 2003
A mathematical sunflower growth model is presented that simulates interactions between plant structure and function. Dual-scale automaton is used to simulate plant organogenesis from germination to maturity on the basis of organogenetic growth cycles that have constant thermal time.

Pattern of Biomass Partitioning into Fractions of Boreal Trees

Biology Bulletin, 2017
Ratios between above- and underground phytomass of tree organs were studied for different forest types. The partitioning of phytomass into tree fractions was described using rank distributions characterizing the relationships between the resource volume available for each tree organ and the ranks of biomass fractions.

A dynamic model of crop growth and partitioning of biomass

Field Crops Research, 1999
A model is presented of growth and partitioning to leaves, stems and roots in herbaceous, vegetative crops in response to atmospheric conditions and water supply. It comprises 12 state variables and 33 parameters (including four functional relationships), all of direct physiological significance.

Modelling Biomass Accumulation and Partitioning in Chickpea (Cicer arietinum L.)

Journal of Agronomy and Crop Science, 2006
Quantitative information regarding biomass accumulation and partitioning in chickpea (Cicer arietinum L.) is limited or inconclusive. The objective of this study was to obtain baseline values for extinction coefficient (K), radiation use efficiency (RUE,

On the Vegetative Biomass Partitioning of Seed Plant Leaves, Stems, and Roots

The American Naturalist, 2002
A central goal of comparative life-history theory is to derive the general rules governing growth, metabolic allocation, and biomass partitioning. Here, we use allometric theory to predict the relationships among annual leaf, stem, and root growth rates (GL, GS, and GR, respectively) across a broad spectrum of seed plant species.

Canonical rules for plant organ biomass partitioning and annual allocation

American Journal of Botany, 2002
Here we review a general allometric model for the allometric relationships among standing leaf, stem, and root biomass (ML, MS, and MR, respectively) and the exponents for the relationships among annual leaf, stem, and root biomass production or “growth rates” (GL, GS, and GR, respectively). This model predicts that ML ∝ MS3/4 ∝ MR3/4 such that MS ∝ MR
