استفاده از پتانسیلهای آللوپاتیک گیاهان مختلف به عنوان روشی بیولوژیک در مدیریت علفهای هرز معرفی شده است. از این رو در این پژوهش نقش پتانسیل آللوپاتیک گونه درمنه (Artemisia aucheri boiss) و همچنین ماده مؤثره موجود در اسانس این گیاه بر درصد جوانه زنی و رشد اولیه دو گونه تاج خروس (Amaranthus retroflexus L.) و پیچک صحرایی (Convolvulus arvensis L.) مورد بررسی قرار گرفت. این بررسی به صورت طرح فاکتور...
تاج خروس وحشیamaranthus retroflexus l. یکی از علف های هرز غالب تابستانه باغ های مرکبات دزفول می باشد. حشره کامل و لارو سرخرطومی (f.) hypolixus pica از این گیاه تغذیه کرده و رشد و تولید مثل آن را مختل می کنند. تغییرات جمعیت این سرخرطومی در یک باغ مرکبات واقع در دزفول با نمونه برداری تصادفی در طول فصل رشد بوته های تاج خروس وحشی و شمارش مراحل مختلف رشدی سرخرطومی روی آن ها مطالعه گردید. این آزمای...
The current study aimed to research the chemical composition, antioxidant, herbicidal and antifungal effect three essential oils, as obtained from Thymus canoviridis Jalas., eriocalyx (Ronni.) Jalas. fallax Fisch. et C.A. Mey. Antioxidant capacities of oils were determined by 1.1dipheny1-2-picrylhydrazyl (DPPH) method. potential was tested in-vitro against Fusarium equiseti (Corda) Sacc., grami...

Seed germination, growth, flowering and yields of kiwano (Cucumis metuliferus E. Meyer Ex. Naudin) were examined in eastern Slavonia during 2021 growing season. The objective this study was to determine agro-morphological diversity within under different weed management practices sowing time. experiment arranged as a 3 x factorial design with three replications. Factors included options (wheat ...
A protozoan flagelate has recently been isolated from Amaranthus retroflexus. This plant grows near economically important crops in southeastern Spain, which are known to be parasitized by Phytomonas spp. The present study focuses on the characterization of the energy metabolism of this new isolate. These flagellates utilize glucose efficiently as their primary energy source, although they are ...
Monoterpenes, the chemical constituents of essential oils found in plants, are known biologically active compounds. The present study was conducted to investigate the inhibitory effects of 30 monoterpenes including monoterpene hydrocarbons and oxygenated monoterpenes on seed germination and seedling growth of Amaranthus retroflexus, Chenopodium album and Rumex crispus under laboratory condition...
