Physiological Responses of Cotton Genotypes to Water-Deficit Stress during Reproductive Development
… of leaves, which consequently would result in osmotic adjustment through accumulation of compatible solutes, increased activity of enzymes, and perturbation of carbohydrates metabolism in leaves and flowers of cotton plants, and differences in drought tolerance among the genotypes would exist. …

Water relations and cutting management of switchgrass
… were measured daily. Leaf water potential (Ψ), osmotic potential (Π), relative water content, and concentrations of K, Na, Ca, and total free sugars were measured at the end of each water-stress cycle. Osmotic potential at full turgor (Π<sub>100</sub>), symplastic water content (SYM) , and …

Evaluation of physiological traits and identification of QTLs for drought tolerance in hexaploid wheat (Triticum aestivum L.).
… ABA content, water status traits (e.g. osmotic adjustment, RWC and leaf water potential), water soluble carbohydrates (WSC) and carbon isotope discrimination (Δ¹ ³C) were measured during experiments. Through these experiments, the drought responses of the three cultivars were …

The influence of low moisture stress on the gas exchange and thylakoid activity of loblolly pine (pinus taeda) and aleppo pine (pinus halepensis)
… electron transport capacity, and needle osmotic potentials were measured. Seedlings of both species were watered only when their needle water potential fell below -1.8 and -2.2 MPa respectively (water stress conditioning) or were kept well watered (controls). After 10 weeks of water …

The effects of exogenous application of abscisic acid and α,α'-dipyridyl on cold acclimation and physical characteristics of Pisum sativum 'Alaska' seedlings
… entails changes in membrane composition, osmotic adjustment, alterations in the cell wall-plasma membrane interface, sugar deposition, and changes in cell wall proteins. There is evidence that a rigid cell wall may be necessary for cold acclimation. Difficulties arise in studying plant …

Physiological response of loblolly pine seedlings to moisture-stress conditioning and their subsequent performance during water stress
… evaluated. Significant decreases in needle osmotic potential occurred in moisture stress conditioned seedlings. As a result, turgor in conditioned seedlings was equal to or greater than control seedlings even at lower needle water potentials. Photosynthesis vas decreased greatly with reduced …

Coordinated Tree Responses to Drought -Vulnerability and Sustainable Production: Hypotheses on Arid Ecosystem Adjustments to Limitations in Water Resources
… increasing soil drought. Q. suber trees adjusted osmotically by a magnitude of 0.7 MPa, while bulk modulus of elasticity (epsilon) increased by a magnitude of 17 MPa. Osmotic adjustment of 0.48 MPa was observed in greenhouse plants of A. tortilis while epsilon declined by a magnitude of 7 MPa in …

Purple nutsedge (Cyperus rotundus L.) competition with cotton: Species biology and effects of proportion, density, and moisture
… photosynthesis in cotton was probably due to the osmotic adjustment that occurred in cotton leaves that protected enzymes and other cellular components during water stress. In additive field experiments, seed cotton yield was reduced because the number of harvestable bolls m⁻¹ was reduced as …

Moisture stress conditioning, potassium nutrition, and tolerance of Salvia splendens 'Bonfire' to moisture stress
… to MSC. MSC and increasing K rate resulted in osmotic adjustment and increased cellular turgor potentials. Foliar K content increased as osmotic potentials decreased due to treatment. Although there was no interaction, MSC and high K rates both reduced transpiration (E), leaf conductance (g₁), …

QUERIES IN QUERCUS: FROM THE DEVELOPMENT OF A TISSUE CULTURE CLONAL PROPAGATION SYSTEM TO THE EVALUATION OF STRESS TOLERANT HYBRID WHITE OAKS FOR THE URBAN ENVIRONMENT
… Q. bicolor reduced its turgor loss point (osmotic adjustment) and maintained gas exchange rates. In contrast, B. pendula shed its leaves, did not reduce turgor loss point, and had varied gas exchange responses. Both species displayed contrasting physiological strategies to cope with drought …

Diferenciación adaptativa entre poblaciones de Pinus canariensis Chr. Sm. ex DC
… in arid environments. Among these responses, osmotic adjustment of dry populations and changes in biomass allocation were remarkable. A longer juvenile stage in Canary Island pine compared with the rest of Mediterranean pines was assessed. In the provenance trials in the Canary Islands and …

Thermo and drought tolerance markers and regulation of heat stress proteins for chickpea (Cicer arietinum L.; Fabaceae) production in NE South Africa
… acclimated to drought than Acc#8 associated with osmotic adjustment on leaf relative water content (RWC) and higher capacity to protect photosynthetic activity, making Acc#7 potentially ideal for areas associated with intermittent drought spells. This observation, however, disapproved the …
