Dynamic modeling of root water uptake using soil moisture data
In this work a dynamic model of water uptake from plants growing in naturally vegetated areas subjected to a rainfall and evaporation time series is described. The model results are compared and contrasted with popular pre-existing models. Also, the effects of the uptake pattern on the movement of water across multiple soil layers are also analyzed. The results showed that contrary to common mo...
متن کاملEvaluation of Macroscopic Root Water Uptake Models Using Lysimeter Data
Three macroscopic root water uptake models (Molz–Remson, Feddes, and Selim–Iskandar) have been widely used in modeling water flow in soil–plant systems. In this article, we use evapotranspiration data and soil water content data obtained from lysimeter measurements and root distribution data obtained in a nearby wheat field to evaluate the accuracy of these root water uptake models in predictin...
متن کاملReconstructing plant root area and water uptake profiles
A major challenge in plant ecology is quantifying how roots interact with the soil to obtain water and nutrients. Stable isotope analysis of hydrogen and oxygen bound in plant and soil water is one of the best and least destructive methods for elucidating plant-soil interactions. Plant roots obtain water from various depths in the soil and the isotopic signature of plant stem water reflects the...
متن کاملRole of a single aquaporin isoform in root water uptake.
Aquaporins are ubiquitous channel proteins that facilitate the transport of water across cell membranes. Aquaporins show a typically high isoform multiplicity in plants, with 35 homologs in Arabidopsis. The integrated function of plant aquaporins and the function of each individual isoform remain poorly understood. Matrix-assisted laser desorption/ionization time-of-flight analyses suggested th...
متن کاملRegulation of root water uptake under abiotic stress conditions.
A common effect of several abiotic stresses is to cause tissue dehydration. Such dehydration is caused by the imbalance between root water uptake and leaf transpiration. Under some specific stress conditions, regulation of root water uptake is more crucial to overcome stress injury than regulation of leaf transpiration. This review first describes present knowledge about how water is taken up b...
