In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...

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, ...

To investigate the effect of herbicide Trifluralin and the role of magnetized water on enzymatic activities and content of proline and growth substances including gibberellin (GA3) and cytokinin (6- benzyl amino purine), an experiment was conducted using squash (Cucurbita pepo L. var. Shiraz Hybrid F1) seedlings. Four levels of trifluralin (0, 5, 15 and 25 ppm) and irrigation by distilled and m...

The objective of this research was to evaluate the effect of salicylic acid and gibberellic acid on germination characteristics and changes of proline, protein and catalase activity of Brassica napus seedlings under Cu(SO4) stress. The experimental design was factorial with complete randomized design as a base design with 3 replications. The first factor was 4 levels of Cu(SO4) stress (0, 10, 2...

The experiment was conducted in 2012 to evaluate the effect of salinity stress on oil percent, oil yield, seed yield and some physiological charactristics on three local populations of castor bean (Ricinus communis L.), at the University of Shahrekord, Iran. Experiment was carried out with three replications in a completely randomized design including five levels of salinity (1.2, 2, 2.6, 3.8 ...

The soil contamination by heavy metals is one of the environmental problems of the world, with deleterious effects on the fauna and flora of soil and groundwater contamination, in addition to reducing plant growth and yield by entering the food chain,  it puts human health and other organisms in denger.Cadmium is one of the hazardous and carcinogenic pollutions that in natural ecosystems ratio ...
