Estimation of water use of Pinus tabulaeformis Carr. in Loess Plateau of Northwest China

open access: yesJournal of Hydrology and Hydromechanics, 2019
Tree transpiration plays a determining role in the water balance of forest stands and in seepage water yields from forested catchments, especially in arid and semiarid regions where climatic conditions are dry with severe water shortage, forestry ...

Changes in Transpiration and Evapotranspiration of Grapevines (Vitis vinifera L.) in Arid Oasis in Northwestern China

open access: yesGuan'gai paishui xuebao, 2021
【Objective】 The ratio of transpiration (T) to evapotranspiration (ET) varies with plants and their growth stages. The aim of this paper is to experimentally study T and ET, as well as their temporal variations.

Continuous increase in evaporative demand shortened the growing season of European ecosystems in the last decade

open access: yesCommunications Earth & Environment, 2023
Despite previous reports on European growing seasons lengthening due to global warming, evidence shows that this trend has been reversing in the past decade due to increased transpiration needs.

Measurement of sap flow dynamics through the tomato peduncle using a non-invasive sensor based on the heat field deformation method [PDF]

open access: yes, 2013
Recent contradicting evidence on the contributions of xylem and phloem to tomato fruit growth highlights the need for a more thorough insight into the dynamics of sap flow through the tomato peduncle. In fact, knowledge on sap flow dynamics through small

Transpiration rates from mature Eucalyptus grandis  ×  E. nitens clonal hybrid and Pinus elliottii plantations near the Two Streams Research Catchment, South Africa [PDF]

open access: yesHydrology and Earth System Sciences, 2023
Pine plantations are the dominant species currently planted within the South African commercial forestry industry. Improvements in bio-economy markets for dissolving wood pulp products have seen an expansion in fast-growing Eucalyptus plantations due to ...

Self-potential signals related to tree transpiration in a Mediterranean climate [PDF]

open access: yesHydrology and Earth System Sciences
Plant transpiration is a crucial process in the water cycle, and its quantification is essential for understanding terrestrial ecosystem dynamics. While sap flow measurements offer a direct method for estimating individual tree transpiration, their ...

Comparing actual transpiration fluxes as measured at leaf-scale and calculated by a physically based agro-hydrological model

open access: yesJournal of Agricultural Engineering, 2023
The main purpose of this paper is to compare the actual transpiration rates from tomato crop, as measured at leaf scale and estimated by a macroscopic approach in an agro-hydrological model, named FLOWS-HAGES, under variable soil properties and water ...

Simple Methods of Measuring the Transpiration of Plants [PDF]

open access: yesNature, 1884
THE “potetometre” described in NATURE, May 22, p. 79, appears to be an ingenious but a rather complicated instrument. Experience has, however, taught me that the extremest simplicity is most desirable. Mr. Ward hints at difficulties of manipulation which are quite conceivable. The plan I have adopted, and find to answer, as far as it goes, is to insert

Flux Measurements in Trees: Methodological Approach and Application to Vineyards

open access: yesItalian Journal of Agronomy, 2008
In this paper a review of two sap flow methods for measuring the transpiration in vineyards is presented. The objective of this work is to examine the potential of detecting transpiration in trees in response to environmental stresses, particularly the ...
