A thermodynamic formulation of root water uptake [PDF]

Hydrology and Earth System Sciences, 2016
By extracting bound water from the soil and lifting it to the canopy, root systems of vegetation perform work. Here we describe how root water uptake can be evaluated thermodynamically and demonstrate that this evaluation provides additional insights ...

Evaluation of the applicability of the root water uptake model on alpine meadows and analysis of root water uptake characteristics

Frontiers in Earth Science, 2022
It is essential to quantify the rate of root water uptake (RWU) and characterize the variability of RWU, which benefits understanding the water use of alpine meadows and its response to environmental changes.

Modeling the influence of rhizodeposits on root water uptake

Vadose Zone Journal
The chemical compounds that plant roots release into the soil, referred to as rhizodeposits, affect soil hydraulic properties like the surface tension and viscosity of soil water, and the contact angle between menisci and the pore surface.

Mechanistically derived macroscopic root water uptake functions: The α and ω of root water uptake functions

Vadose Zone Journal
Water uptake by plant roots is an important component of the soil water balance. Predicting to what extent potential transpiration from the canopy, that is, transpiration demand, can be met by supply of water from the soil through the root system is ...

The Role of Aquaporins in Root Water Uptake [PDF]

Annals of Botany, 2002
The capacity of roots to take up water is determined in part by the resistance of living tissues to radial water flow. Both the apoplastic and cell-to-cell paths mediate water transport in these tissues but the contribution of cell membranes to the latter path has long been difficult to estimate. Aquaporins are water channel proteins that are expressed

A model for water uptake by plant roots [PDF]

Journal of Theoretical Biology, 2004
We present a model for water uptake by plant roots from unsaturated soil. The model includes the simultaneous flow of water inside the root network and in the soil. It is constructed by considering first the water uptake by a single root, and then using the parameterized results thereby obtained to build a model for water uptake by the developing root ...

Nitrogen forms affect root structure and water uptake in the hybrid poplar [PDF]

, 2011
The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field experiment.

Root water uptake patterns are controlled by tree species interactions and soil water variability [PDF]

Hydrology and Earth System Sciences
Root water uptake depends on soil moisture which is primarily fed by throughfall in forests. Several biotic and abiotic elements shape the spatial distribution of throughfall.

Label-free quantitative proteomics of maize roots from different root zones provides insight into proteins associated with enhance water uptake

BMC Genomics, 2022
Background Maize is one of the most important food crops worldwide. Roots play important role in maize productivity through water and nutrient uptake from the soil.

Stochastic soil water dynamics of phreatophyte vegetation with dimorphic root systems [PDF]

, 2009
As the direct uptake of deep groundwater by vegetation may be essential in semiarid regions, we incorporated this process in stochastic root zone water balance models.
