Tobacco is a salt-sensitive glycophyte crop species. In this work effect of silicone (Si) supplementation (1 mM as Na2SiO3) was studied in Nicotiana rustica L. cv. Basmas grown hydroponically in growth chamber under control, low (25 mM) and high (75 mM) NaCl concentration for two weeks. Dry matter production of leaves was depressed by salinity level as low as 25 mM and higher salt concentration...
Drought Stress is one of the most important limiting factors in plants growth and development. Growth regulator, Trinexapac-ethyl, might improve drought stress resistance via reducing stem growth and improving osmotic adjustments. In present study Trinexapac-ethyl effect on some tall fescue var Rebel physiological and morphological traits under irrigation free conditions was studied. So, an exp...
In order to study the effects of biofertilizers of nitroxin (0, 2, 4 L.h-1) and biosulphur (0, 2, 4 kg.h-1) Containing “plant growth promotor Bacteria” on quantity and quality of medicinal plant of winter cherry (Physalis alkekengi L.) an experiment in a factorial experiment based on randomized complete block design with nine treatments (Nitroxin 2 and 4 L.h-1, Biosulphur 2 and 4 kg.h-1, Nitrox...
This experiment was conducted to investigate the effect of drought stress and vermicompost biofertilizer on some morphological, physiological and biochemical characteristics of Thymus vulgaris in greenhouse of Khorramabad Agricultural and Natural Resources Research and Training Center in a completely randomized design with three replications. The pot experiment was performed. Factors included v...
اثرات اسید سالیسیلیک بر برخی از ویژگیهای مورفو-فیزیولوژیکی و بیوشیمیایی دانهال گردو تحت تنش شوری
Salinity of water irrigation and soil are of the major factors affecting plant growth and productivity worldwide. In this research the effects of salicylic acid on some morpho-physiological and biochemical characteristics of walnut (Juglans regia) seedlings under salinity stress condition were studied. The experiment was a two-factor factorial experiment arranged in completely randomized design...
In this research, the effects of 5-aminolevulinic acid, as a key precursor in the biosynthesis of porphyrin compounds such as chlorophyll, in mitigating salt stress were studied in Lycopersicum esculentum mill. Salinity at three levels (0, 50 and 75 mM NaCl) and ALA treatment at three levels (0, 1 and 2 mM) were applied on plants of this species. Both levels of salt (50 and 75 mM) reduced shoot...
Raphanus sativus L., /7-Carotene, Carotenoid Composition, Chlorophyll a-Proteins, LightHarvesting Chlorophyll, Localization of Carotenoids, Lutein, Neoxanthin The uneven distribution of carotenoids and chlorophylls between several chlorophyllcarotenoid-proteins isolated from radish chloroplasts by SDS-polyacrylamide-gel electrophoresis is described. Lutein and neoxanthin are enriched in the lig...
in this research, effect of vermicompost and plant growth promoting rhizobacteria (pgpr) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at karaj research institute of forest and rangelands. experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...
microalgae can produce various natural products such as pigments, enzymes, unique fatty acids and vitamins that benefit humans. the objective of the study was evaluation of carotenoids (beta carotene, zeathanthin, lutein, lycopene and astaxanthin) and chlorophyll a in spirulina microalgae. spirulina powder has been produced by jordan’s method in iran. carotenoids were extracted from spirulina p...
abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...
