The present study was conducted at Genetics Department, Hazara University Garden Campus and during 2008-09 as a part of PhD study. Seed dormancy breaking, germination tests of 2 wild speciesi.e., O. longistaminata and O. rufipogon and 3 local cultivated rice varieties/ germplasm i.e., Swat-1, F. Malakand and JP-5 were conducted under different treatments. Hulled seeds were exposed to: constant ...

Red rice is a troublesome weed in rice-growing areas of the southern U.S. Red rice in Arkansas may be diverse enough to warrant some adjustments in weed control programs. A study was conducted at the Rice Research and Extension Center (RREC), Stuttgart, Ark., in 2003 to determine the phenotypic diversity of red rice in Arkansas. One hundred thirty-six red rice accessions were collected from 26 ...

The mycelial growth rates in lineal growth assay, yield, and production rate of five Pleurotus ostreatus strains were evaluated in response to different levels of Mn(II) and/or NH4+ in a substrate containing sunflower seed hulls as a main energy and nutritional component. Each strain showed different basal values for mycelial growth rate and biological efficiency on sunflower seed-hull substrat...

BACKGROUND Cotton is an important domesticated fiber used to manufacture a variety of products and industrial goods. During harvesting with cotton strippers and cotton pickers, it is contaminated with foreign matter from botanical and non-botanical sources which adversely affect the quality and consistency of cotton, and therefore reduces its market value. To improve the current grading done by...

this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...

Biofortification of foods, achieved by increasing the concentrations of minerals such as iron (Fe) and zinc (Zn), is a goal of plant scientists. Understanding genes that influence seed mineral concentration in a model plant such as Arabidopsis could help in the development of nutritionally enhanced crop cultivars. Quantitative trait locus (QTL) mapping for seed concentrations of calcium (Ca), c...

-Biosorption potential of sunflower seed hull to remove reactive textile dye contaminated solutions was the purpose of this investigation. Azure A chloride dye was chosen as a model for this investigation. Pretreatment, initial pH, biomass dosage, contact time, initial dye concentration and temperature were evaluated in batch mode studies. Preliminary results indicate that acid and base pretrea...
