Abstract Water deficit in the soil leads to osmotic stress in plants. The type of stress affects plant water relations, osmolyte accumulation and oxidative stress balance. The present study aimed to investigate the effects of osmotic stress on the Croatian perennial species Fibigia triquetra (DC.) Boiss, adapted to a hot and dry habitat. Plants grown in culture conditions were subjected to isoosmotic concentrations of mannitol and polyethylene glycol (PEG) and certain physiological and… Expand

Physiological Attributes of Peg Induced Water Stress in Pearl Millet Hybrid(SKNAU)
Seven hybrids of Pearl millet have been taken for the investigation of growth and physiological attributes of PEG induced water stress. The observations were taken at two stages i.e. 10 and 20 DAS. AExpand
Physiological responses of two halophytic grass species under drought stress environment
TLDR
Comparative physiological performance and antioxidant enzymes activity of both halophytic grasses under drought stress showed considerable sensitivity to a water deficit condition, more so in C. ciliaris than in H. mucronatum. Expand

Influence of NaCl and mannitol on peroxidase activity and lipid peroxidation in Centaurea ragusina L. roots and shoots.
TLDR
Several POD isoforms (P3, P4 and P9) were specifically induced by salinity and drought and change in the POD isoenzyme pattern of treated plants was in accordance with the activity change in time. Expand
Response of the cherry rootstock to water stress induced in vitro
The in vitro response of sweet cherry (Prunus cerasus × P. canescens) rootstock Gisela 5 to increasing water deficit in the culture medium was studied. Water stress induced by the incorporation of 1,Expand
Salt tolerance of Centaurea ragusina L. is associated with efficient osmotic adjustment and increased antioxidative capacity
TLDR
The results suggest that the major reason for the particular threshold of salinity tolerance in C. ragusina can be attributed to limited dilution capacity of succulent tissue and osmotic adjustment achieved through salt ions uptake as a dominant strategy but also highly inducible antioxidative defense.

Osmotic stress-induced alterations in rice (Oryza sativa L.) and recovery on stress release
TLDR
It is inferred that the duration and magnitude of stress applied in the present experiments did not cause major permanent alterations in the rice cultivar ‘Kranti’, and the significant basic information gathered in such experiments, particularly on recovery potential, can be utilised for varietal screening.

Comparative study of the effects of mannitol and PEG osmotic stress on growth and solute accumulation in Sesuvium portulacastrum
Abstract Responses to osmotic stress were studied in Sesuvium portulacastrum , a halophyte potentially usable for saline soil stabilization and covering. Cuttings were multiplicated and cultivated inExpand
Alterations in Photochemical and Physiological Activities of Chickpea (Cicer arietinum L.) Cultivars under Drought Stress
TLDR
Although Canitez recovered quickly from drought stress and exhibited a good ability to overcome drought stress, via activation of many protection mechanisms such as increasing antioxidant enzymes and proline and anthocyanin accumulation during vegetative stage, the results show that canitez is less drought tolerant than Gokce.

Influence of drought on some physiological parameters symptomatic for oxidative stress in leaves of chives (Allium schoenoprasum)
Abstract Drought, created by withholding water, led to significant reductions in the absolute (−3.6%) and relative (−24.8%) water content of chives ( Allium schoenoprasum ) leaves, a significant riseExpand
Drought-induced responses of photosynthesis and antioxidant metabolism in higher plants.
TLDR
This review focuses on the ability and strategies of higher plants to respond and adapt to drought stress, including proline and glycine-betaine, as well as the role of abscisic acid under drought stress conditions. Expand
Dissecting the roles of osmolyte accumulation during stress
TLDR
In re-assessing the functional significance of compatible solute accumulation, it is suggested that proline and glycine betaine synthesis may buffer cellular redox potential and contribute to stress-tolerant phenotypes observed. Expand
Role of proline under changing environments
TLDR
Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species within normal ranges, thus preventing oxidative burst in plants.
