field experiment was conducted in order to determine the effect of wheat seeding rate and time of application of sulfosulfuron for control of hordeum spontaneum in wheat field in 2007 in qom province, iran. the experimental design was completely randomized block with four replications in which treatments were arranged as factorial. the treatments were wheat seed rates at 250, 275 and 300 kg/ha ...

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation...

laboratory studies were conducted to examine the effects of different concentrations of wild barley (hordeum spontaneum koch.) shoot and seed extracts on germination and seedling growth of wheat (triticum aestivum l.) and wild barley. in this study, all wild barley shoot extract concentrations (with exception of lowest concentration) significantly reduced wheat seed germination after 7 days. sh...

Cereals such as barley and wheat are unable to germinate under anoxic conditions. Data are presented on the utilization of the soluble sugars present in the dry seed of wheat and barley kept under strict anoxia, together with the status of the enzymes involved in the metabolism of carbohydrates. The amount of glucose, fructose, and sucrose decreases during the anaerobic treatment, indicating th...

Hexaploid Wheat (Triticum aestivum L.) is one of the most important food cereals grown in many areas worldwide. World population is to increase by 2.6 billion in 2050. Ethiopia is one of the world’s nine countries needed to increase food production. Since few studies on genetic diversity & in adequate evaluation of bread wheat varieties; my objective the project is to study genetic diversity of...

Wheat, oats, barley, rye, rice, and millet are all considered small grains. These small grains are carbohydrate and vitamin rich and have become food staples for humans and animals worldwide. Small grains have been cultivated by man for thousands of years and through selective breeding, they have become one of the most productive crops grown by man. Small grains have been adapted to grow in nea...
