The decoupling factor (Ω) reflects the leading mechanisms responsible for canopy transpiration and allows to know relevance of control stomatal or conductance on (T). Ω is strongly dependent water availability can be a good approach describe how plants minimize excessive loss by increasing dominance biotic factors that controls evapotranspiration under deficit conditions. We provided an overvie...

Growing conditions such as water supply and soil fertility influence oregano morphological development physiological responses. Our study aimed to analyse the responses of plants grown under different bokashi application rates. The experiment was carried out in a greenhouse randomized block design 3 x 4 factorial scheme. Treatments encompassed three replacement levels (60, 80, 100% crop evapotr...

Following planting, western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings experience water stress and declining xylem pressure potential (Psi(x)). Low Psi(x) can result in xylem cavitation and embolism formation, causing a decline in hydraulic conductance. This study focused on the relationship between Psi(x), xylem cavitation and transpiration (E) of newly planted seedlings. Leaf specifi...

erophylla (Raf.) Sarg.) seedlings experience water stress and declining xylem pressure potential (Ψx). Low Ψx can result in xylem cavitation and embolism formation, causing a decline in hydraulic conductance. This study focused on the relationship between Ψx, xylem cavitation and transpiration (E) of newly planted seedlings. Leaf specific hydraulic conductance (kAB) declined from 0.56 to 0.09 m...

Leaf conductance, water relations, growth, and abscisic acid (ABA) concentrations in xylem sap, root apices and leaves were assessed in oak seedlings (Quercus robur L.) grown with a root system divided between two compartments and subjected to one of four treatments: (a) well watered, WW; (b) half of root system exposed to soil drying and half kept well watered, WD; (c) whole root system expose...

Long-term hydraulic acclimation to resource availability was explored in 3-year-old Populus deltoides Bartr. ex Marsh. clones by examining transpiration, leaf-specific hydraulic conductance (G(L)), canopy stomatal conductance (G(S)) and leaf to sapwood area ratio (A(L):A(S)) in response to irrigation (13 and 551 mm year(-1) in addition to ambient precipitation) and fertilization (0 and 120 kg N...

The fact that silicon application alleviates water deficit stress has been widely reported, but the underlying mechanism remains unclear. Here the effects of silicon on water uptake and transport of sorghum seedlings (Sorghum bicolor L.) growing under polyethylene glycol-simulated osmotic stress in hydroponic culture and water deficit stress in sand culture were investigated. Osmotic stress dra...
