The drought tolerance of canola cultivars viz., Shirale, Oscar, Con-II, Rainbow and 19H was investigated after exposure to drought stress at various growth stages in a pot experiment. Water stress was imposed at flowering and pod filling growth stages. Data of various physiological (leaf chlorophyll a & b, proline and protein contents) and agronomic attributes (number of pods/plant, seeds/pods,...

Drought stress was generated by PEG 6000. Water potentials were: zero as the control, and –0.15, –0.49, –1.03, and –1.76 MPa as treatments. After 24-h treatment the total soluble protein content of 2 maize (Zea mays L.) cultivars (704 and 301) was determined and SDS-PAGE gel electrophoresis in the first dimension was performed. By decreasing water potentials, total soluble protein content first...

Cold shock proteins (CSPs) enhance acclimatization of bacteria to adverse environmental circumstances. The Escherichia coli CSP genes CspA and CspB were modified to plant-preferred codon sequences and named as SeCspA and SeCspB. Overexpression of exogenous SeCspA and SeCspB in transgenic Arabidopsis lines increased germination rates, survival rates, and increased primary root length compared to...

The present study was designed to clarify the effects of salinity and water intercross stresses on the growth and physiobiochemical characteristics of Tamarix chinensis seedlings by pots culture under the artificial simulated conditions. The growth, activities of SOD, POD, and contents of MDA and osmotic adjusting substances of three years old seedlings of T. chinensis were studied under differ...

a major problem of arid and semi-arid regions is environmental stresses like salinity and drought. to study the effect of artichoke germination under different levels of salinity and drought, two separate experiments were performed. the experimental treatments included different salinity levels of nacl (0, 50, 100, 150 mm) and five drought levels by peg (0, 10%, 15%, 20% and 25%) with three rep...

Lycium depressum L. is the only native tree-like life-form species inhabited in saline and alkaline regions of Turkmen Sahra located at Golestan province in Northern Iran. During past years, efforts have been made to increase vegetation cover of the area by cultivation of L. depressum L. to reduce water and wind erosions and dust storm challenges; however, the cultivation of t...

to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...

Global climate change is predicted to increase temperatures, alter geographical patterns of rainfall and increase the frequency of extreme climatic events. Such changes are likely to alter the timing and magnitude of drought stresses experienced by crops. This study used new developments in the classification of crop water stress to first characterize the typology and frequency of drought-stres...

Salicylic acid can mitigate the impacts of salinity and drought stresses in crops. To study the effect of salicylic acid under iso-osmotic drought and salt stresses on nutrients absorption and growth of linseed (Linum usitatissimum L.), an experiment was conducted based on a completely randomized design with three replications in Yasouj University in 2016. Treatments included salinity and droug...

Drought is one of the most important abiotic stress factors affecting crop yields and qualities worldwide. One drought-sensitive plant cucumber, which has a high transpiration rate. Grafting recognized as promising approach to increasing tolerance stresses in cucumber. In this study, it aimed determine rootstock that will prevent negative changes some growth, physiological genetic parameters cu...
