Two experiments were conducted under field and greenhouse conditions, to investigate the effect of herbal spraying chlormequat chloride (CCC) (0 and 2.5 g. L-1), soil incorporation of Zinc sulfate (Zn) at the three rates of 0, 25 and 50 kg ha-1, and pre-treatment of seeds with bio-fertilizer Nitroxin (Nit) in a randomized complete block design with a factorial arrangement and three replications...

To examine the response of three rapeseed varieties to salinity stress, a pot experiment was conducted in a glasshouse using a factorial experiment based on a randomized complete block design with three replications. Three levels of NaCl (0, 100 and 200 mM NaCl) were imposed as the salinity treatments at root establishment (leaf 4) stage. In this study, sodium (Na+) and potassium (K+) concentra...

This study was conducted to investigate the effect of type and ratio of vermicompost on tomato growth, with five different types of vermicompost (platanus leaves, maple leaves, pruning apple trees and grape, waste of herbal extracts and azolla residues) and four ratios of vermicompost to peat and perlite (2:1 v/v) as 0, 1:3, 2:3 and 3:3, at greenhouse conditions. Results showed that type of ver...

Water deficit stress is the main limiting factor of crop growth and yield in arid and semi-arid environments. Hyssop (Hyssopus officinalis L.) is one of the most important medicinal plants that have numerous medical uses. In order to study the effect of drought stress on physiological and morphological traits of Hyssop, an experiment based on randomized completely design was conducted with four...

Because of increasing trend in salinization of water sources, and inevitable using non-traditional water, a research was planned to determine the tolerance range of strawberry cv. Paros to salinity and possible role of salicylic acid (SA) in ameliorating its adverse effect on plant growth. In this research, effect of different salinity levels (0, 20 and 40 mM in nutrient solution) and SA (0, 10...

abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...

Magnesium plays a key role in photosynthesis, partitioning of carbohydrates, phloem export of sucrose, photo-oxidation and leaf chlorosis of plants. In order to evaluate the effect of various concentrations of Mg (0 (control), 2 and 4 mM) in the nutrient solution and root zone temperature (RZT) (15, 25 and 35 ºС) on growth, yield and physiological properties in cucumber (Cucumis sativus L. cv. ...
