avena sativa/potassium

Fly ash (FA) and bottom ash (BA) from a softwood pellet boiler were characterized and evaluated as soil amendments. In a greenhouse study, two plant species (rye grass, Lolium perenne L. and oats, Avena sativa) were grown in three different treatments (1% FA, 1% BA, non-amended control) of a silty

Some physical and chemical properties of four oat (Avena sativa L.) varieties (BDMY-6, BDMY-7, Che-Chois and Y-2330) harvested from Konya in Turkey were investigated. The weight of the grain, moisture, crude protein, crude ash, crude fibre, crude energy, crude oil and water-soluble extract contents

The purpose of this study was to determine the effect of soil contamination with Hg on the yield and chemical composition of Avena sativa L. Mercury was incorporated into soil in amounts: 0, 50, 100 and 150 mg Hg·kg^-1of soil. Zeolite, lime and bentonite were used to alleviate the

Segments of oat (Avena sativa L.) roots which had been exposed to 1 millimolar CdSO(4) in quarter-strength Hoagland No. 1 solution exhibited decreased respiratory rates, ATP levels, membrane-bound ATPase activity, and reduced K(+) fluxes. Respiration and ATP levels were decreased after a 2-hour

The effect of abscisic acid (ABA) on uptake of potassium ((86)Bb(+) or (42)K(+)) by Avena sativa L. coleoptile sections was investigated. ABA lowered the potassium uptake rate within 30 min after its application and inhibition reached a maximum (ca. 75%) after 2 h. The inhibition of K(+) uptake

The possibility was investigated that diethylstilbestrol (DES) inhibits potassium absorption in oat (Avena sativa L. cv. Goodfield) roots by inhibiting mitochondrial functions in addition to inhibiting the plasma membrane ATPase. DES at 10(-6) molar stimulated the mitochondrial ATPase slightly, but

OBJECTIVE Animal studies report that oat (Avena sativa L) intake has favorable effects on kidney function. However, the effects of oat consumption have not been assessed in humans. The aim of this study was to examine the impact of oat intake on biomarkers of renal function in patients with chronic

The purpose of this study was to determine the remediation effect of various substances (manure, clay, charcoal, zeolite and calcium oxide) on limiting the influence of high cobalt doses (0, 20, 40, 80, 160 and 320 mg/kg of soil) on the content of macroelements in grain, straw and roots of oat. The

K(+) and Na(+) fluxes and ion content have been studied in roots of Atriplex nummularia Lindl. and Avena sativa L. cv Goodfield grown in 3 millimolar K(+) with or without 3 or 50 millimolar NaCl. Compartmental analysis was carried out with entire root systems under steady-state conditions.Increasing

The particulate glucan synthetase preparation isolated from a homogenate of oat coleoptiles at 4 C lost 65% of its original activity after 1 day when the UDP-d-glucose substrate concentration was 5 x 10(-7)m to 1.0 x 10(-6)m. Storage of the particulate enzyme at -20 C or in liquid nitrogen did not

Inland vertebrate predators could enrich of nutrients the local top soils in the area surrounding their nests and dens by depositing faeces, urine, and prey remains and, thus, alter the dynamics of plant populations. Surprisingly, and in contrast with convincing evidence from coastal habitats,

Lignin concentration can be measured in plants by the acetyl bromide-soluble lignin spectrophotometric method; however, as with any spectrophotometric method, a reliable standard is needed. In the present experiments, lignin was extracted from each of the forages under study with the acetyl bromide

During a growing season in 2004, 231 leaf samples of virus infected and mosaic and dwarf mosaic symptoms showing maize (Zea mays L.) plants and 258 leaf samples of mosaic showing johnsongrass (Sorghum halepens L.) plants from various corn fields in Tehran province were collected. Serological tests

Slow callus growth is a barrier to efficient genetic transformation in some gramineous species. A reformulation of Murashige and Skoog (MS) medium, with additional magnesium sulphate, potassium phosphate, copper sulphate, proline and glutamine, termed WPBS medium, has been developed which improves

Uptake of the lipophilic cation triphenylmethylphosphonium into mesophyll protoplasts of oat (Avena sativa L. cv. "Garry") approaches equilibrium at 3 to 4 hours. The resulting external and internal concentrations are then used with the Nernst equation to obtain a membrane potential of -62
