Carbon partitioning mechanisms in POTATO under drought stress

Plant Physiology and Biochemistry, 2020
Potato (Solanum tuberosum) is an important food crop consumed all over the world, but it is generally sensitive to drought conditions. One of the major physiological processes affected by drought stress is carbon partitioning: the plant's choice of where

Influence of carbon partitioning kinetics on final austenite fraction during quenching and partitioning [PDF]

Scripta Materialia, 2009
The quenching and partitioning (Q&P) process is a two-stage heat-treatment procedure proposed for producing steel microstructures that contain carbon-enriched retained austenite.

Carbon partitioning to cellulose synthesis

Plant Molecular Biology, 2001
This article discusses the importance and implications of regulating carbon partitioning to cellulose synthesis, the characteristics of cells that serve as major sinks for cellulose deposition, and enzymes that participate in the conversion of supplied carbon to cellulose.

PARTITIONING OF METALS TO SEDIMENT ORGANIC CARBON

Environmental Toxicology and Chemistry, 1996
AbstractThe partition coefficients and sorption capacities for cadmium, copper, and lead in freshwater sediments are derived from fitting a Langmuir isotherm to data from 14 sediments. The metal activity in the solution phase was measured using specific ion electrodes. The metal sorption due to acid-volatile sulfide was subtracted from the total sorbed

Stability of the thin partitioned carbon nanotubes

Journal of Molecular Modeling, 2013
We report on the research of the stability of partitioned (bamboo-like) carbon nanotubes with different diameters. The stability of the partitioned carbon nanotubes of the smallest diameter were determined by the tight-binding method. For the prediction of the destruction regions of the bamboo-like nanotubes atomic framework subjected to strain the new

Carbon partitioning in forage crops

Acta Biotheoretica, 1991
The paper describes the conceptual models used to understand the processes determining plant growth rates in response to environmental changes. A series of experiments and growth models were used at three organizational levels: the specific plant organs, the whole plant and the plant canopy.

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.

Carbon assimilation, partitioning and budget modelling.

2008
Abstract In this chapter, the uptake and metabolism of carbon by specific sink tissues of peach, and broader aspects of carbon partitioning and utilization at the whole-plant level are discussed. Topics covered consisted of: carbon assimilation, leaf photosynthetic characteristics, fruit photosynthesis, canopy carbon assimilation, carbon ...
