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...

The ABCC multidrug resistance associated proteins (ABCC-MRP), a subclass of ABC transporters are involved in multiple physiological processes that include cellular homeostasis, metal detoxification, and transport of glutathione-conjugates. Although they are well-studied in humans, yeast, and Arabidopsis, limited efforts have been made to address their possible role in crop like wheat. In the pr...

The development of alien addition lines is important for transferring useful genes from exotic species into common wheat. A hybrid of common wheat cv. 7182 (2n = 6x = 42, AABBDD) and Psathyrostachys huashanica Keng (2n = 2x = 14, NsNs) via embryo culture produced the novel intergeneric disomic addition line 59-11. The seed morphology of 59-11 resembled the parent 7182 and it exhibited extreme a...

Introduction Stand establishment is the first step in producing a good wheat crop, and most producers intend to obtain a uniform stand of wheat. However, intentions are not always the same as reality when it comes to wheat establishment. A study conducted in the early 1990s by the OSU Small Grains Extension Program compared producer perception of wheat seeding accuracy with actual field measure...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...
