-T~~ intensity of intraspecific competition under different levels of light and nitrogen supply was assessed for the temperate zone herb, Chenopodium album. Plants were grown at two densities (one or six plants/pot) in a modified factorial design with three levels each of light and nitrogen availability. This yielded five light/nitrogen treatments which comprised two gradients, one extending fr...
abstract nowadays, environmental pollution by heavy metals is one of the most serious threats of the world which needs effective remediation actions. the aim of this study was to investigate the potential use of atriplex [atriplex verucifera], salicornia [salicornia europaea] and chenopodium album in simultaneous uptake and accumulation of na and cd or pb in two calcareous soils with different ...
Background: The cultivation of saffron is expanding through the southeast of Iran, and allergy to saffron pollen occurs in workers involved in processing this plant. We aimed to clone, sequence and express a major allergen involved in saffron pollen allergy, and to compare the recombinant with the natural allergen. Methods: The N-terminal amino acid sequence of Cro s 1, an allergen from saff...
The current study was designed to conduct the physicochemical, phytochemical and gas chromatography- mass spectrometry analysis of Chenopodium album Stellaria media L. Methanolic extract dried leaves prepared subsequently fractionated using different solvents like hexane, chloroform, ethyl acetate. Obtained plant fractions were analyzed for presence secondary metabolites screening methods. Furt...
This article is devoted to work aimed at normalizing the condition of degraded soils in open-pit mines as a result anthropogenic influences through phytomass. By creating biological cover from plants, it has been achieved improve composition soil. Plants such Datura starmonium, Portuluca oleracea, Caspella bursa-pastoris, Chenopodium vulvaria, album, Plantago lanceolata, Vaccaria hispanica, Vic...
A precise prediction of the yield losses inflicted by weeds is the basis of decisions in weed management. Hitherto, only rough estimates, which neglect the specific production situation, have been available for vegetable crops. In this study a simple simulation model was developed to estimate yield loss by radiation competition as a function of environmental variables. In the model, the distrib...
در طی این تحقیق آناتومی برگ در گونه‌های Kochia prostrata, Chenopodium album و Noaea mucronata ازخانواده اسفناج مورد مطالعه قرار گرفت. تراکم روزنه درواحد سطح، و اندازه و نوع روزنه، تراکم کرک ونوع آنها مقایسه گردید. مشخصات برگ در برش عرضی بیانگر آناتومی کرانزدر دو گونه میباشد.تغییرات ساختمانی برگ از جمله بافت ذخیره کننده آب بیانگر سازش این نوع گیاهان در زیستگاههای خشک است.
