Selenium uptake and its antioxidant role in ryegrass cultivars as affected by selenite seed pelletization

Effects of time and dietary selenium concentration as sodium selenite on tissue selenium uptake by sheep.

Thirty crossbred wethers (60 kg avg initial wt) were used to study the time-dose response to dietary Se as sodium selenite (Na2SeO3). Sheep were fed a basal diet (.20 mg/kg Se, M basis) for 10 d; three wethers were killed and tissues were collected for controls. The remaining 27 sheep were assigned randomly to diets supplemented with either 3, 6 or 9 mg/kg Se (as-fed basis) from reagent grade N...

Growth and chemical composition of three pistachio cultivars as affected by soil salinity and boron fertilization

Supplementation of Micronutrient Selenium in Metabolic Diseases: Its Role as an Antioxidant

Selenium is an essential mineral naturally found in soil, water, and some of the food. As an antioxidant, it is one of the necessary trace elements in human body and has been suggested as a dietary supplement for health benefit. Although the human body only needs a trace amount of selenium every day, plenty of recent studies have revealed that selenium is indispensable for maintaining normal fu...

Isabgol (Plantago ovata Forsk) seed germination and emergence as affected by environmental factors and planting depth

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
