Accurate and rapid detection of bacterial plant pathogen is the first step toward disease management and prevention of pathogen spread. Bacterial plant pathogens Clavibacter michiganensis subsp. nebraskensis (Cmn), Pantoea stewartii subsp. stewartii (Pss), and Rathayibacter tritici (Rt) cause Goss's bacterial wilt and blight of maize, Stewart's wilt of maize and spike blight of wheat and barley...

The effects of grazing winter wheat (Triticum aestivum) by Canada geese (Branta canadensis) was assessed in 3 fields during 2 years of experimentation at the Wye Research and Education Center, Queenstown, Maryland. Randomly placed wire enclosures prevented goose grazing on 11.1 m sq. control plots. Grazed plots were marked in each field soon after the geese migrated in March. Grazed plots had c...

Abstract One of the most important traits that plant breeders aim to improve is grain yield which a highly quantitative trait controlled by various agro-morphological traits. Twelve morphological such as Germination Percentage, Days Spike Emergence, Plant Height, Length, Awn Tillers/Plant, Leaf Angle, Seeds/Spike, Thickness, 1000-Grain Weight, Harvest Index and Maturity have been considered ind...

20 hulless barley lines were assessed by grain yield and other agronomic traits in 2006 and 2007 in the research station of the university of tabriz, iran. the experiments in each year were carried out as randomized complete block design with four replications. the genotypes were significantly different for most of the studied traits. this indicated the existence of large genetic variation in t...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...

In order to study the genetic conditions of some agronomic traits in wheat, a cross was made between Gaspard and Kharchia varieties. F2, F3 and F4 progenies with parents were evaluated under drought conditions. Three-parameter model [m d h] considered as the best fit for number of fertile tiller and flag leaf length using generations mean analysis method. For number of grain per spike and main ...

BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

This article presents the results of studies effectiveness use biological products in winter wheat crops. The positive effect pre-sowing seed inoculation with Azotofit and Help Growth on germination capacity seeds Skagen variety has been established which was 3-4% higher than control contributed to an increase number nodal roots by 56% 50%, respectively, plant density 13-9 pcs / m2 more control...
