The effects of phosphate processing wastewater (PPWW) on heavy metal accumulation in a Mediterranean soil (Tunisia, North Africa) were investigated. Moreover, the residual toxicities of PPWW-irrigated soils extracts were assessed. Results showed that heavy metal accumulation was significantly higher in PPWW-irrigated soil extracts than in control soil. The heavy metal accumulation increased ove...
The chemical composition of the essential oil of the flowering aerial parts of Monarda didyma L. cultivated in central Italy was analyzed by Gas Chromatography/Mass Spectrometry (GC/MS). The major compounds of the oil were thymol (59.3%), p-cymene (10.3%), terpinolene (9.2%), δ-3-carene (4.4%), myrcene (3.7%), and camphene (3.4%). The essential oil was tested in vitro for its anti-germination a...
Three new compounds, apetalumosides C₁ (1), D (2), and 1-thio--d-glucopyranosyl(1→1)-1-thio-α-d-glucopyranoside (3), together with twenty-two known ones (4-25) were obtained from the seeds of Lepidium apetalum Willd. Among the known isolates, 5-8, 10-13, 16-20, and 25 were obtained from the genus for the first time; 4, 14, 15, and 21-24 were isolated from the species for the first time. Meanwhi...
A major challenge in basic research into homeopathic potentisation is to develop bioassays that yield consistent results. We evaluated the potential of a seedling-biocrystallisation method. Cress seeds (Lepidium sativum L.) germinated and grew for 4 days in vitro in Stannum metallicum 30x or water 30x in blinded and randomized assignment. 15 experiments were performed at two laboratories. CuCl...
Lepidium draba (Brassicaceae) is a major concern for agriculture and biodiversity in the western United States. As current control methods do not provide long-term, sustainable solutions, research has been conducted to find biological control agents. Ceutorhynchus assimilis is one of the currently investigated candidates. Known as oligophagous in the literature, a specialist clade of this root-...
Garden cress (Lepidium sativum L.) is a test-plant for studying the toxicity of substrates, which basis phytotesting. Dangerous pollutants are surfactants contained in household chemicals, including cosmetics. The purpose work to investigate cosmetics micellar water on phytotest with garden and analyze it possible effects human health environment. Investigated available retail network Ukraine m...
copper is a micronutrient which its, deficiency can alter essential functions in plant metabolism. on the other hand, excess copper is present in certain regions and environments, and can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species that damage cells. in this study, we examined the effect interactions between various concentrations of sodium n...
شوری خاک در مناطق خشک و نیمه خشک یکی از تنش های اصلی گیاهان قلمداد می شود که می تواند اثر منفی بر تولید محصول داشته باشد. در پژوهش حاضر، به علت اهمیت دارویی و غذایی گیاه شاهی، اثر برهم کنش شوری (225 میلی مولار nacl) و آسکوربیک اسید (1 میلی مولار) بر رشد و روابط آبی آن بررسی شد. آزمایش در قالب طرح کاملا تصادفی با چهار تکرار در شرایط تنظیم شده انجام گرفت. نتایج نشان داد که شوری موجب کاهش رشد، محت...
abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...
