Design and implementation of a low-cost device for measuring sap flow in woody species

open access: yesDyna, 2019
Transpiration is a key variable in water balance. Sap flow measurement methods allow to estimate transpiration at plant level, but scalable at the stand, river basin or ecosystem level.

Using the sensitivity of biomass production to soil water for physiological drought evaluation

open access: yesSoil and Water Research, 2008
The analysis of drought as a phenomenon and the proposal of how to define and quantify the deficiency of water in soil for plants, so called physiological drought, are described. The presented approach is based on the theoretical considerations supported

The potential of a confined closed greenhouse in terms of sustainable production, crop growth, yield and valuable plant compounds of tomatoes

open access: yesJournal of Applied Botany and Food Quality, 2014
A confined closed greenhouse (CGH) was applied to save energy and to investigate how tomatoes respond to specific microclimatic conditions. As such, new dynamic set-points for precise climate control were used in the CGH compared to those applied in a ...

Predicting Tree Sap Flux and Stomatal Conductance from Drone-Recorded Surface Temperatures in a Mixed Agroforestry System—A Machine Learning Approach

open access: yesRemote Sensing, 2020
Plant transpiration is a key element in the hydrological cycle. Widely used methods for its assessment comprise sap flux techniques for whole-plant transpiration and porometry for leaf stomatal conductance.

ROOT CONTRACTION IN TRANSPIRING PLANTS [PDF]

open access: yesNew Phytologist, 1982
SUMMARYExperimental data published previously (Faiz and Weatherley, 1977) emphasized the existence of considerable hydraulic resistance in the perirhizal soil of rapidly transpiring plants. This was evident when soil water potential (Ψs in the root zone was as high as −2 or −3 bars.

Growth and gas exchange of corn under salt stress and nitrogen doses [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2021
The excess of salts can affect several processes in the crops, and nitrogen (N) can attenuate the depressive effect of salinity. The objective was to evaluate the influence of nitrogen doses on the growth and gas exchange of corn crop irrigated with ...

On the transpiration current in plants [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1907
Abstract In a paper published in 1905, professor Ewart investigates the question as to what force is required to move water through the waterways of plants at the same velocity as the transpiration current. His general conclusion is that the resistance is so great that neither are sufficient forces generated in the leaves o raise the ...

Research advances in nighttime transpiration and its eco-hydrological implications

open access: yesShui kexue jinzhan, 2014
It is generally assumed that transpiration does not occur at night because leaf stomata are opened during the day and closed at night. Nonetheless,there is increasing evidence that the stomata are opening in many species and in a range of habitats at ...

Evapotranspiration and components of corn (Zea mays L.) under micro irrigation systems in a semi-arid environment

open access: yesSpanish Journal of Agricultural Research, 2020
Aim of study: This work summarizes the influence of surface drip irrigation (DI) and subsurface drip irrigation (SDI) systems on corn growth indices and actual evapotranspiration (ETc-act) and its components of plant transpiration (Tp) and soil ...
