Assessment of phytotoxicity of parthenin.
Phytotoxicity of parthenin, a sesquiterpene lactone, was evaluated against four weedy species (Amaranthus viridis, Cassia occidentalis, Echinochloa crus-galli, and Phalaris minor) through a series of experiments conducted under laboratory or greenhouse conditions to assess its herbicidal potential. Under laboratory conditions, parthenin (0.5-2 mM) severely reduced seedling growth (root and shoo...
متن کاملNanoparticles based on essential metals and their phytotoxicity
Nanomaterials in agriculture are becoming popular due to the impressive advantages of these particles. However, their bioavailability and toxicity are key features for their massive employment. Herein, we comprehensively summarize the latest findings on the phytotoxicity of nanomaterial products based on essential metals used in plant protection. The metal nanoparticles (NPs) synthesized from e...
متن کاملClassification and clinical assessment.
There are at least nine classification criteria for psoriatic arthritis (PsA) that have been proposed and used in clinical studies. With the exception of the ESSG and Bennett rules, all of the other criteria sets have a good performance in identifying PsA patients. As the CASPAR criteria are based on a robust study methodology, they are considered the current reference standard. However, if the...

15 صفحه اولChemical Speciation and Phytotoxicity of Heavy Metals in Sewage Sludge for the Germination of Chinese Cabbage Seeds
Single extractions with distilled water and diethylene-triamine-pentaacetic acid (DTPA), and a sequential extraction procedure were conducted in this study to determine the chemical speciation of Cd, Cr, Cu, Ni, Pb and Zn in four municipal sewage sludges and subsequently evaluate the phytotoxicity of the metals by a seed germination test of Chinese cabbage (Brassica chinensis L.). Analytical re...
