An experiment was carried out to investigate the effect of progressing water deficit stress on leaf water relation parameters and compatible solutes at different phenological stages. Completely randomized design including four phenological stages (as drought stress treatments) was used. Each treatment had five replicates. Variables measured were osmotic potential (&PsiS), relative water content...

Plant growth regulators (PGRs), which are widely used in agriculture, have various effects on different morphological and physiological characteristics of wheat cultivars. To examine the effect of two PGRs [cycocel (CCC) and salicylic acid (SA)] on some morphological and physiological properties of bread (Roshan) and durum (Yavarous) wheat cultivars under different irrigation regimes [normal (a...

Water deficiency stress as the most important abiotic stress plays an important role in the yield suppression of plants worldwide. Considering physiological indices to improve drought resistance is of paramount importance. The objective of present study was to evaluate the effects of different irrigation intervals (irrigation after 5, 7, 9 and 11 days) and rates of superabsorbent polymer (Nil, ...

Cadmium (Cd) is easily absorbed by the root system in many plant species and due to its solubility in water and toxicity is considered as a major pollutant. The aim of this study was investigation of cadmium toxicity on some physiological characteristics of lentil seedlings. So, two-week-old plantlets were treated with different concentrations (0 as control, 0.125, 0.25, 0.5, 1, 2.5 and 5 μM...

This research was performed to compare Pb and Cd accumulation in root and leaves of pinus brutia. The effects of these elements in different concentrations (0, 200, 500 and 1000) on the amount of proline, soluble sugar of the plant were also investigated. The experiment was done in a factorial design in three replicates. The concentration of Pb and Cd in leaves and root were measured by atomic ...
