A biotype of Stellaria media (L.) Vill. has been identified that is highly resistant to the herbicide chlorsulfuron. Resistance is due to an altered acetolactate synthase (ALS) that is much less sensitive to chlorsulfuron than the ALS from the susceptible (S) biotype. The S biotype was extremely sensitive to D489 (N-[2,6-dichlorophenyl]-5,7-dimethyl-1,2,4-triazolo[1,5a] pyrimidine-2-sulfonamide...
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...
بانک بذر خاک به منظور مدیرت مرتع بدلیل بازبابی تنوع زیستی جوامع رویشگاهی پس از بروز شرایط نامطلوب و یا تخریب از اهمیت بسزایی برخوردار است. آتش سوزی توسط فعالیت های انسانی بر فرایندهای اکولوژیکی مربوط به بانک بذر خاک و ساختار جوامع رویشگاهی اثر می گذارد. این تحقیق در سال 1390 به منظور بررسی اثر آتش سوزی بر پوشش گیاهی مراتع حاجی قوشان در شمال شهرستان گنبد که در سال 1389 آتش سوزی شده، در دو منطقه...
Summary Allelopathic effects of different plant allelochemicals have become the focus studies that aim to determine new pesticidal compounds. Plant extracts with chemical compositions can be obtained using methods extraction, whereas dealing allelopathic properties use biotests obtain fast and precise results. Such were undertaken after noticing industrial hemp (Cannabis sativa L.) on surroundi...
Biomass reduction and amino acid content in plants of Papaver rhoeas L. and Stellaria media L. were investigated to evaluate response of these species to herbicide stress under various temperature (25/16 and 8/2 C) and relative humidity (50 and 75%) regimes. Weeds were treated with tribenuron methyl (15 g × ha), a mixture of 2.4-D with florasulam (180 + 3.75 g × ha), and a mixture of 2.4-D with...
