The aim of the present study was to evaluate the effect of osmotic stress caused by polyethylene glycol (PEG) 6000 in hydroponic culture on wheat seedlings of drought-resistant Chinese Spring (CS) and drought-susceptible SQ1 cultivar, and to examine the alleviative role of exogenous polyamines (PAs) applied to the medium. The assessment was based on physiological (chlorophyll a fluorescence kinetics, chlorophyll and water content) as well as biochemical (content of carbohydrates, phenols…

Sodium Nitroprusside and Putrescine Mitigate PEG-Induced Drought Stress in Seedlings of Solanum lycopersicum
Crop plants all over the world face an array of environmental threats among which drought is found to be the most deleterious. The present investigation was carried to test the efficacy of
Effect of Acetaminophen (APAP) on Physiological Indicators in Lactuca sativa
Pronounced correlation was described between chlorophyll fluorescence parameters and yield mainly under APAP conditions, and plants are more sensitive to chronic contamination compared to acute.


Alleviation of Osmotic Stress Effects by Exogenous Application of Salicylic or Abscisic Acid on Wheat Seedlings
SA and ABA ameliorate, particularly in the tolerant wheat cultivar, the harmful effects and after effects of osmotic stress induced by PEG in hydroponics through better osmosis adjustment achieved by an increase in proline and carbohydrate content as well as by a increase in antioxidant activity.
Impact of osmotic stress on physiological and biochemical characteristics in drought-susceptible and drought-resistant wheat genotypes
The level of osmotic stress defined in this study as most suitable for differentiating drought resistance of wheat genotypes will be used in further research for genetic characterization of this trait in wheat through QTL analysis of mapping population of doubled haploid lines derived from CS and SQ1.
Interaction of polyamines, abscisic acid and proline under osmotic stress in the leaves of wheat plants
Results suggest that the connection, which exists between polyamine metabolism and abscisic acid signalling leads to the controlled regulation and maintenance of polyamine and proline levels under osmotic stress conditions in wheat seedlings.
Modulation of the polyamine biosynthetic pathway in transgenic rice confers tolerance to drought stress.
It is demonstrated clearly that the manipulation of polyamine biosynthesis in plants can produce drought-tolerant germplasm, and a model consistent with the role of polyamines in the protection of plants against abiotic stress is proposed.
Polyamine biosynthesis of apple callus under salt stress: importance of the arginine decarboxylase pathway in stress response.
Results indicated that the ADC pathway was tightly involved in the salt stress response and the possible physiological role of putrescine in alleviating stress damage.
Effects of exogenous putrescine on gas-exchange characteristics and chlorophyll fluorescence of NaCl-stressed cucumber seedlings
Non-photochemical quenching of the singlet excited state of chlorophyll a (NPQ) showed quite different manner from the others, namely, continued to enhance during the experiment, and the reduction was alleviated till the control level by treatment with Put.
Spermine accumulation under salt stress.
The data presented suggest that spermine accumulation is not a salt tolerance trait and no reduction in leaf injury associated with salt stress in both cultivars.
