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.

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 ...

Modeling the influence of rhizodeposits on root water uptake
Vadose Zone JournalThe 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.

Vadose Zone JournalWater 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 ...

Root water uptake patterns are controlled by tree species interactions and soil water variability [PDF]
Hydrology and Earth System SciencesRoot 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.

A root is a root is a root? Water uptake rates of Citrus root orders [PDF]
Plant, Cell & Environment, 2010 ABSTRACTKnowledge about the physiological function of root orders is scant. In this study, a system to monitor the water flux among root orders was developed using miniaturized chambers. Different root orders of 4‐year‐old Citrus volkameriana trees were analysed with respect to root morphology and water flux.
