PARTITIONING OF GRAPEVINE BIOMASS IN THINNED SHOOTS

Acta Horticulturae, 2000
In the viticultural areas where appreciated wines are produced, it is very important to keep quantity production under control if better quality is to be achieved. The main cultivation techniques used to control the production are pruning and cluster or berry thinning.

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.

Global Allocation Rules for Patterns of Biomass Partitioning in Seed Plants

Science, 2002
A 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 ...

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

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.
