Abstract Over the past century, agricultural landscapes worldwide have increasingly been managed for primary purpose of producing food, while other diverse ecosystem services potentially available from these often undervalued and diminished. The incorporation relatively small amounts perennial vegetation in strategic locations within dominated by annual crops—or perennialization—creates an opportunity enhancing provision a wide range goods to society, such as water purification, hydrologic...
Abstract. Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, carbon budgets at the land–atmosphere interface. However, despite being main land evaporative flux global scale, its response environmental drivers are currently not well constrained by observations. Here we introduce first compilation whole-plant data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized...

Abstract Reduced stomatal conductance ( g s ) during soil drought in angiosperms may result from effects of leaf turgor on stomata and/or factors that do not directly depend turgor, including root‐derived abscisic acid (ABA) signals. To quantify the roles turgor‐mediated and turgor‐independent mechanisms decline drought, we measured responses water relations three woody species (almond, grapevine olive) under a range conditions designed to generate independent variation root diurnal...
The control of plant transpiration by stomata under water stress and recovery conditions is paramount importance for performance survival. Although both chemical hydraulic signals emitted within a are considered to play major role in controlling stomatal dynamics, they have rarely been assessed together. aims this study were evaluate (i) the dynamics at leaf, stem root level, (ii) their effect on regulation conductance (gs) during recovery. Measurements gs, potential, abscisic acid (ABA)...
The decrease of stomatal conductance (gs) is one the prime responses to water shortage and main determinant yield limitation in fruit trees. Understanding mechanisms related closure response imposed stress crucial for correct irrigation management. loss leaf hydraulic functioning considered as major factors triggering closure. Thus, we conducted an experiment quantify dehydration (Kleaf) its impact on gs two Mediterranean tree species, deciduous (almond) evergreen (olive). Our hypothesis was...
1. Some plant functional traits evolved with high temporal resource variability and disturbance in ecosystems where these factors are prevalent. Persistence of characteristics may depend on continued disturbance, which turn promote diversity. In Mediterranean ecosystems, experiments that eliminate needed to detect trait dependence factors. 2. The purpose this study was experimentally assess how interannual rainfall variability, summer drought seasonal grazing modify the (life span, flowering...
A major challenge in studies estimating stand water use mixed-species forests is how to effectively scale data from individual trees the stand. This case for forest ecosystems northeastern USA where differences among species and across different size classes have not been extensively studied, despite their relevance a wide range of ecosystem services. Our objectives were assess importance sources variability on transpiration upscaling explore potential impacts future shifts composition...
Despite the importance of understanding plant growth, mechanisms underlying how and fruit growth declines during drought remain poorly understood. Specifically, it remains unresolved whether carbon or water factors are responsible for limiting as progresses. We examine questions regarding relative to depending on deficit level stage by measuring diameter, leaf photosynthesis, a proxy cell turgor in olive (Olea europaea). Flow cytometry was also applied determine division stage. found that...
Effective study and management of crops forests would benefit greatly from useful plant-based indicators the biological controls on evapotranspiration, particularly stomatal conductance (gs). Given strong influence gs bulk leaf water potential turgor pressure (P), in vivo measurement P may provide information about diurnal or seasonal dynamics gs. Moderate plant stress affects as leaf-to-air vapour deficit (D) varies, these correlate to Here, we explored relative changes response D under...
The differential stomatal regulation of transpiration among plant species in response to water deficit is not fully understood, although several hydraulic traits have been reported influence it. This knowledge gap partly due a lack direct and concomitant experimental data on transpiration, conductance, traits. We measured sap flux density (Js), conductance (gs), different five crop species. Our aim was contribute establishing the causal relationship between consumption its using trait-based...
