Stomatal responsiveness to evaporative demand (air vapour pressure deficit (VPD)) ranges widely between species and cultivars, and mechanisms for stomatal control in response to VPD remain obscure. The interaction of irrigation and soil moisture with VPD on stomatal conductance is particularly difficult to predict, but nevertheless is critical to instantaneous transpiration and vulnerability to desiccation. Stomatal sensitivity to VPD and soil moisture was investigated in Semillon, an…

Abscisic Acid Down-Regulates Hydraulic Conductance of Grapevine Leaves in Isohydric Genotypes Only1[OPEN]
TLDR
It is proposed that the observed response of Kleaf to ABA may be part of the overall ABA regulation of leaf water status, and variation between isohydry and anisohydry correlated with Kleaf sensitivity to A BA.
A comparison of root and shoot hydraulics, aquaporin expression and leaf gas exchange between two grapevine cultivars reveals differences in hydraulic control mediated by aquaporins
TLDR
The results reinforce the hypothesis that both hydraulic and chemical signals significantly contribute to the differences in water conservation behaviours of the two cultivars.
Differences in osmotic adjustment, foliar abscisic acid dynamics, and stomatal regulation between an isohydric and anisohydric woody angiosperm during drought.
TLDR
It is concluded that a large range in ΨTLP and biphasic ABA dynamics are indicative of anisohydric species, and these traits are associated with exposure to low minimum foliar water potential, dense sapwood and large resistance to xylem embolism.
Adaptive strategies of two Mediterranean grapevines varieties (Aragonez syn. Tempranillo and Trincadeira) face drought: physiological and structural responses
TLDR
It is suggested that there is variation among the genotypes and the main physiological parameters for variety selection, for drought, were leaf water potential, stomatal conductance and reflectance indexes.
Response of grapevine (Vitis vinifera L.) leaves to different leaf fertilizers under a semi-arid condition
TLDR
Leaf chlorophyll content had a significant positive correlation with leaf protein content when all the observations were pooled, and the organic leaf fertilizers can be considered as a safe, sustainable and innovative strategies to support plants to cope with drought.

TLDR
There was a strong, but negative correlation be- tween leaf temperature and air humidity for all the cultivars, and tleaf showed a strong rela- tionship with Tair for allThe cultivars.

Does night-time transpiration contribute to anisohydric behaviour in a Vitis vinifera cultivar?
TLDR
Night-time and daytime water loss and insufficient stomatal regulation therefore account for the tendency to anisohydric behaviour shown by Semillon.
Variability among species of stomatal control under fluctuating soil water status and evaporative demand: modelling isohydric and anisohydric behaviours
TLDR
Stomatal conductance of well-watered plants had no response to VPD when plants were grown in natural soils, suggesting that the opposite result observed in many laboratory experiments might be linked to the low unsaturated hydraulic conductivity of usual potting substrates.
Partial rootzone drying and deficit irrigation increase stomatal sensitivity to vapour pressure deficit in anisohydric grapevines
TLDR
Application of PRD and DI increased stomatal closure in response to conditions of high evaporative demand making the vines behave in a more isohydric-like manner, suggesting that a long distance root-based chemical signal such as ABA may be responsible for the changes inStomatal behaviour.

TLDR
This unusual pattern of hydraulic regulation, referred to here as isohydrodynamic, is explained by a hydromechanical stomatal control model where plant hydraulic conductance is dependent on transpiration rate.
DIURNAL CHANGES IN WATER RELATIONS AND ABSCISIC ACID IN FIELD‐GROWN VITIS VINIFERA CULTIVARS
TLDR
It is suggested that ABA uptake from the xylem causes partial stomatal closure during the afternoon and plays a key role in the control ofStomatal conductance in field grown vines by optimizing the relationship between CO2 uptake and water loss.
Hydraulic and chemical signalling in the regulation of stomatal conductance and plant water use in field grapevines growing under deficit irrigation.
TLDR
The data suggest that hydraulic feedback and feed-forward root-to-shoot chemical signalling mechanisms might be involved in the control of stomata in response to decreased soil water availability, hydraulic signals playing the dominant role.
Early stomatal closure in waterlogged pea plants is mediated by abscisic acid in the absence of foliar water deficits
TLDR
The results provide an example of stomatal closure brought about by stress in the root environment in the absence of water deficiency, and appear to be an inhibition of ABA transport out of the shoots of flooded plants, causing the hormone to accumulate in the leaves.
