خارلته ((l) scop cirsium arvense) سومین علف هرز مهم در دنیا و یکی از مهمترین علف های هرز در باغات و مزارع ایران می باشد. به منظور دست یابی به یک روش غیر شیمیایی مبتنی بر اصول اکولوژیک برای کنترل گیاه هرز خارلته و امکان سنجی استفاده از حشرات بومی برای کنترل آن مطالعات صحرایی و آزمایشگاهی انجام گرفت، مطالعات مقدماتی شامل جمع آوری، شناسایی و ارزیابی تاثیر حشرات گیاهخوار بر کاهش زیست توده، مرگ و می...
The flowers, roots and stems of Cirsium species are used as a folk remedy in Anatolia. In order to evaluate antioxidant activity of Cirsium hypoleucum which is an endemic plant, superoxide radical (hypoxanthine-xanthine oxidase system) and free radical scavenging activities (DPPH) using in vitro electron spin resonance (ESR) spectrometry of the different extracts, fractions and compounds obtain...
Five terpenes (1-5), three fatty acids (6-8), two sterols (9 and 11), and a monogalactosyldiacyl glycerol (10) were isolated from the methylene chloride extract of the aerial part of Cirsium setidens. Their chemical structures were determined to be alpha-tocopherol (1), 25-hydroperoxycycloart-23-en-3beta-ol (2), 24-hydroperoxycycloart-25-en-3beta-ol (3), mokko lactone (4), transphytol (5), 9,12...
Comparative analyses of complete chloroplast (cp) DNA sequences within a species may provide clues to understand the population dynamics and colonization histories of plant species. Equisetum arvense (Equisetaceae) is a widely distributed fern species in northeastern Asia, Europe, and North America. The complete cp DNA sequences from Asian and American E. arvense individuals were compared in th...
PURPOSE To evaluate the acute hepatotoxicity of Equisentum arvense L. in rats. METHODS Fifty Wistar rats were used, these being divided in four groups, one being the control (receiving only water) and the other groups receiving graded doses of Equisentum arvense L. (30, 50, and 100mg/kg respectively) for 14 days. Blood samples were obtained to determine TGO, TGP, FA, DHL and GT-gamma activiti...
Due to the emerging danger life of animals and people, today there is a turn safe technologies for controlling weeds by physical methods, both from point view ecology food safety, which include destruction plants using an electric current, in particular, high-voltage electrical pulses. The purpose study presented article identify evaluate effect pulses on irreversible damage intracellular struc...
Sunflower is the most important oil crop in Republic of Croatia. In last two decades, it has been grown on average 33,506 ha with a grain yield 2.66 t/ha. Weeds represent one causes biotic stress, and their action reflected competition for nutrients, water, light space. The weed flora sunflower crops Croatia extremely diverse, we will often meet: Polygonum persicaria L., lapathifolium Ambrosia ...
The creeping perennial weed species Cirsium arvense (L.) Scop. occurs in patches. Expanding roots allow these patches to increase their covered area. This characteristic has rarely been addressed when investigating the effects of control options arable fields. We designed a three-year field experiment (2019–2021) north-eastern Germany, accounting for existing patch patterns. experimental setup ...
