background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...
Effect of Leaching on Reducing the Phytoxicity of Some Medicinal Plants on Wheat (Triticum aestivum)
The aim of this study was to investigate the effect of leaching on the reduction of soybean (Glycin max), black cumin (Nigella sativa), dill (Anethum graveolens) and dragonhead (Dracocephalum moldavica) residues allelopathy in wheat (Triticum aestivum) cropping. The experiment was conducted in a completely randomized design with three replications in 2017. The factors consisted of four types of...
A 50-yr study at Fairbanks, AK, was started in 1984 to determine soil seed longevity of 17 weed species. Seeds were buried in mesh bags 2and 15-cm deep and were recovered 0.7, 1.7, 2.7, 3.7, 4.7, 6.7, 9.7, 19.7, and 24.7 yr later. Viability was determined using germination and tetrazolium tests. By 24.7 yr after burial (YAB), no viable seeds were found for common hempnettle, flixweed, foxtail b...
in this study, the quantity and quality of essential oil (eo) of chamomile cv. ‘bodegold’, moldavian dragonhead cv. ‘szk1’ and fennel cv. ‘soroksari’ were evaluated in shahrekord climate condition in spring 2014, shahrekord university. chamomile’ flowers and dragonhead’ herb were harvested at full flowering stage. fennel’ fruits were harvested at waxy and full-matured stages. the eo content of ...
Allelopathic effects of plant residues is an important research avenue regarding optimization of rotation systems in agronomy. The aim of this study was to investigate the allelopathic effects of four plant residues, namely, black cumin, dragonhead, dill, and soybean on the germination and growth of wheat (Triticum aestivum) in different cropping systems. Results showed that applicatio...
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...
abstract in order to evaluate the effects of biofertilizers on yield and morphological characters in dragonhead, an experiment based on randomized complete block design with four replications was conducted in 2008. treatments were nitroxin, biological phosphorus, biosulfur, nitroxin+biological phosphorus, biological phosphorus+ biosulfur, nitroxin+ biosulfur, nitroxin+biological phosphorus+ bio...
The aim of the study was to analyze influence bagasse from Moldavian dragonhead (D. moldavica L.) seeds as a source valuable nutrients on physicochemical properties rice milk ice cream. basic composition cream modified with varied proportion (MDB) (1.0%, 1.5%, 2.0%, 2.5%, and 3.0%). analysis fatty acids showed high linolenic acid (n-3) in tested cream, especially 3.0% share bagasse. addition MD...
