Drought reduces water uptake in beech from the drying topsoil, but no compensatory uptake occurs from deeper soil layers

New Phytologist, 2021
Summary The intensity and frequency of droughts events are projected to increase in future with expected adverse effects for forests. Thus, information on the dynamics of tree water uptake from different soil layers during and after drought is crucial ...

Water Uptake by Artemisia ordosica Roots at Different Topographic Positions in an Alpine Desert Dune on the Northeastern Qinghai–Tibet Plateau

Frontiers in Earth Science, 2022
Different strategies of water uptake by roots in a semi-arid desert are one way that plants adapt to the water-limited environment. In this study, stable isotopes of δ18O were used to analyze the variability in water sources of the native species ...

Water Uptake and Water Diffusivity of Seeds [PDF]

Plant Physiology, 1976
When pea (Pisum sativum) seeds were wetted, a sharp front separated the wet and dry portions, the seeds swelled, and the water content in the wetted portion continued to increase for a long time. A model was proposed and tested that takes into account these three characteristics and in particular does not postulate a constant diffusivity.

Effects of Active and Passive Modified Atmosphere Packaging on the Vase Life and Quality of Narcissus (Narcissus tazetta L.) ‘Shahla’ Cut Flowers

Journal of Horticultural Research, 2023
The production of ornamental flowers in the horticultural sector is costly; therefore, finding treatments to reduce postharvest losses and extend the vase life of cut flower is essential in this industry.

Uncorrected soil water isotopes through cryogenic vacuum distillation may lead to a false estimation on plant water sources

Methods in Ecology and Evolution, 2023
Successful use of stable isotopes (δ2H and δ18O) in ecohydrological studies relies on the accurate extraction of unfractionated water from different types of soil samples.

Defoliation‐induced compensatory transpiration is compromised in SUT4‐RNAi Populus

Plant Direct, 2020
The tonoplast sucrose transporter PtaSUT4 is well expressed in leaves of Populus tremula × Populus alba (INRA 717‐IB4), and its inhibition by RNA‐interference (RNAi) alters leaf sucrose homeostasis.

Bark-Water Interactions Across Ecosystem States and Fluxes

Frontiers in Forests and Global Change, 2021
To date, the perspective of forest ecohydrologists has heavily focused on leaf-water interactions – leaving the ecohydrological roles of bark under-studied, oversimplified, or omitted from the forest water cycle.

Optimizing agricultural water use through simulation of soil water content and water uptake under soil moisture and irrigation water salinity stresses: Case study of corn roots using SWAP model [PDF]

Environmental Resources Research, 2021
In order to evaluate soil water content and water uptake by corn plant roots (Single cross 260) under different soil moisture and water salinity stresses using the agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model, an experiment was conducted in

Water uptake depth is coordinated with leaf water potential, water use efficiency and drought vulnerability in karst vegetation.

New Phytologist, 2020
Root access to bedrock water storage or groundwater is an important trait allowing plant survival in seasonally dry environments. However, the degree of coordination between water uptake depth, leaf-level water use efficiency (WUEi) and water potential ...

Effect of Planting Time and Corms Treatment with Gibberellic Acid on Growth, Flowering, and Vase Life of Freesia hybrida ‘Corona’

Journal of Horticultural Research, 2021
Freesia hybrida is one of the most important cut flowers with a short vase life. The present study was conducted to explain the effect of the two planting dates December 1st and 15th and soaking corms before planting in gibberellic acid at concentrations
