LOW DOSES OF FENOXAPROP-P-ETHYL CAUSE HORMESIS IN LITTLESEED CANARYGRASS AND WILD OAT

Radiation hormesis and adoptive response induced by low doses of limiting radiation

  Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems  to be induced at low doses of exposure. In recent decades, however, some pioneer scientists have indicated that ionizing radiation like many other essential agents has toxic effects  ...

ability of adjuvants in enhancing the performance of pinoxaden and clodinafop propargyl herbicides against grass weeds

adjutants' ability in enhancing the performance of herbicides is a major priority in adjuvant research. to identify an appropriate adjuvant for pinoxaden and clodinafop propargyl herbicides against littleseed canarygrass (phalaris minor retz.), common wild oat (avena fatua l.) and ryegrass (lolium temulentum l.), three separate experiments were conducted under greenhouse conditions. in all...

Flow Injection Spectrophotometric Determination of Fenoxaprop-p-ethyl Herbicide in Different Grain Samples after Derivatization

Propomos um método espectrofotométrico para a determinação do herbicida fenoxaprop-p-etil, usando injeção em fluxo.O fenoxaprop-p-etil foi convertido num ácido hidroxamico, na presença de hidroxilamina dihidrocloridrica em meio alcalino. O ácido hidroxâmico obtido reagiu com ferro(III) formando um complexo hidroxamato de ferro(III), vermelho. A absorbância do complexo foi medida a 500 nm em sis...

High-throughput sequencing reveals differential regulation of miRNAs in fenoxaprop-P-ethyl-resistant Beckmannia syzigachne

Non-target site resistance (NTSR) to herbicides is an increasing concern for weed control. The majority of previous studies have focused on metabolic resistance mechanisms of NTSR, but no research exists on gene regulation mechanisms behind herbicide resistance, such as microRNA (miRNA). Here, we identified 3 American sloughgrass (Beckmannia syzigachne Steud.) populations containing fenoxaprop-...

Effects of capsaicin in low doses and high doses on the small intestine motor response in wild-type and TRPV1 knockout mice
