objective: in order to study the effect of drought stress, salicylic acid (sa) and  jasmonic acid (ja) foliar application on hill reaction and photosynthetic pigments. methods:experiment was done as factorial on the basis of completely randomized design in 4 replications. irrigation in 3 levels (fc,   fc and  fc), salicylic acid in 2 levels (0 and 0.5 mm) and jasmonic acid in 2 levels (0 and 50...

to study the effects of chitosan at 0.5 (c1), 0.1 (c2), 0.05 (c3) and 0.01 (c4) (weight percent) concentrations, distilled water (c5) and one percent acetic acid (c6) as controls on physiological and morphological characteristics of two landrace and modified (szk-1) dragonhead (dracocephalum moldavica l.) varieties, a factorial experiment was conducted in completely randomized design in germina...

Aromatic plants are rich in essential oils with considerable antimicrobial properties.The aim of this study was to investigate chemical composition, antimicrobial activity and antioxidant properties of Melissa officinalis and Deracocephalum moldavica essential oils (EOs). The identification of chemical constituents of the EOs was carried out using gas chromato-graphy-mass spec...

Abstract The environmental benefits of agroforestry systems are well known. However, current knowledge potential allelopathic interactions is inadequate. decrease in soil fertility, the increasingly rhapsodic distribution precipitation, and special metabolism cultivation medicinal aromatic plants all harbingers medicinal-agroforestry systems. authors aimed to discover effects Juglans regia L. P...

in order to investigation the effect of different fertilization treatments on nutrient and essential oil contents in dragonhead drug (dracocephalum moldavica l.), an experiment was conducted in the station of agricultural research in urmia on 2008. treatments (nitroxin, barvar phosphate biofertilizer, biosulfur, nitroxin+ barvar phosphate biofertilizer, barvar phosphate biofertilizer + biosulfu...
