Vine water status is a key factor in grape ripening and vintage quality for red Bordeaux wine. How can it be assessed for vineyard management purposes?

OENO One, 2009
Aims: The impact of water deficit stress on vine shoot growth, berry weight, grape composition and overall vintage quality was investigated in Bordeaux vineyards. Methods for assessing water deficit stress were compared.

Deficit Water Volume in Hnilec River in Slovakia [PDF]

Aerul şi Apa: Componente ale Mediului
In this study, water deficit volumes were determined in the Hnilec River catchment in selected hydrological stations in the period 1961-2020, divided into three twenty-year periods (1961-1980, 1981-2000 and 2001-2020).

Water deficit modifies the carbon isotopic composition of lipids, soluble sugars and leaves of Copaifera langsdorffii Desf. (Fabaceae)

Acta Botânica Brasílica, 2017
Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage caused by water deficiency.

Berry flavonoids are differently modulated by timing and intensities of water deficit in Vitis vinifera L. cv. Sangiovese

Frontiers in Plant Science, 2022
In this work, we tested the effect of different regulated deficit irrigation (RDI) regimes on berry flavonoid content and its relative biosynthetic pathways.

Raman spectroscopy‐based diagnostics of water deficit and salinity stresses in two accessions of peanut

Plant Direct, 2021
Water deficit and salinity are two major abiotic stresses that have tremendous effect on crop yield worldwide. Timely identification of these stresses can help limit associated yield loss. Confirmatory detection and identification of water deficit stress

Impact of water-deficit stress on tritrophic interactions in a wheat-aphid-parasitoid system. [PDF]

PLoS ONE, 2017
Increasing temperature and CO2 concentrations can alter tritrophic interactions in ecosystems, but the impact of increasingly severe drought on such interactions is not well understood.

Developing a Crop Water Production Function for Alfalfa under Deficit Irrigation: A Case Study in Eastern Colorado

Agriculture, 2023
Recent Colorado, USA water law provisions allow a portion of irrigation water to be leased between agricultural and other users. Reducing consumptive use (CU) through deficit irrigation while maintaining some crop production could allow farmers to earn ...

Soil water deficits decrease the internal conductance to CO2 transfer but atmospheric water deficits do not [PDF]

Journal of Experimental Botany, 2008
The internal conductance to CO2 supply from substomatal cavities to sites of carboxylation poses a large limitation to photosynthesis. It is known that internal conductance is decreased by soil water deficits, but it is not known if it is affected by atmospheric water deficits (i.e. leaf to air vapour pressure deficit, VPD).

Drought tolerance of sugarcane propagules is improved when origin material faces water deficit.

PLoS ONE, 2018
Drought stress can imprint marks in plants after a previous exposure, leading to plant acclimation and a permissive state that facilitates a more effective response to subsequent stress events.

Proline and sodium nitroprusside increase the tolerance of Physalis peruviana L. plants to water deficit through chemical priming

Ciência e Agrotecnologia, 2022
Water deficit is the main cause of abiotic stress to which plants are susceptible, whether cultivated or those that are underexploited, such as Physalis peruviana L.
