Exploring aquaporin functions during changes in leaf water potential. [PDF]
Front Plant Sci, 2023 Maintenance of optimal leaf tissue humidity is important for plant productivity and food security. Leaf humidity is influenced by soil and atmospheric water availability, by transpiration and by the coordination of water flux across cell membranes throughout the plant.

Revista Brasileira de Engenharia de Biossistemas, 2022 For grasses and other crops in general, soil water potential has been widely studied to determine if there is a deficit or excess of water content in the soil. However, the plant water absorption process is not only modulated by soil water potential but also by the combination of meteorological, soil depth, and crop canopy factors, which could be ...

Should we delay leaf water potential measurements after excision? Dehydration or equilibration? [PDF]
BMC Plant BiolBackground Accurate leaf water potential (Ψw) determination is crucial in studying plant responses to water deficit. After excision, water potential decreases, even under low evaporative demand conditions, which has been recently attributed to the ...

Leaf water potential of coffee estimated by landsat-8 images. [PDF]
PLoS One, 2020 Traditionally, water conditions of coffee areas are monitored by measuring the leaf water potential (ΨW) throughout a pressure pump. However, there is a demand for the development of technologies that can estimate large areas or regions. In this context, the objective of this study was to estimate the ΨW by surface reflectance values and vegetation ...

A few words on grapevine leaf water potential
IVES Technical Reviews, vine and wine, 2020 The majority of vineyards are grown under limiting water supply, with consequences on grapevine physiology, berry growth and composition/quality versus wine styles. Assessing vine water status is crucial to understand vine function and to optimize drought mitigation strategies, such as irrigation.

Soil moisture and soybean physiology affected by drought in an integrated crop-livestock system [PDF]
Pesquisa Agropecuária Brasileira, 2016 : The objective of this work was to evaluate the impact of grazing intensities after 11 years of an integrated crop-livestock system, under no-tillage, on soil moisture and soybean physiological parameters during a summer season affected by drought.

Chloroplast Response to Low Leaf Water Potentials [PDF]
Plant Physiology, 1973 Electron transport in chloroplasts isolated from desiccated sunflower (Helianthus annuus L. cv. Russian Mammoth) leaves was compared with electron transport in sunflower chloroplasts in sorbitol-containing media having various osmotic potentials. In media having low osmotic potentials and dichloroindophenol as electron acceptor, the activity for ...
