(2014-03-07)Mango is one of the most important and popular tropical fruits for people around the world due to its taste, appearance and excellent overall nutritional source from which lead to a heavy demand in world fruit market. With ... -
Fusarium-Artenspektren an Halmbasis und Körnern von Weizen in unterschiedlichen Weizenfruchtfolgen
(2013-12-03)In the present study the composition of Fusarium species spectra on stem bases and grains of wheat and their colonization rates were investigated under the conditions of a wheat crop rotation experiment existing since 2006. ... -
Identification of Export Opportunities for Syrian Citrus Growers to the EU: A Supply Chain Perspective
(2013-07-19)Syrian agriculture faces new opportunities in a liberalized trading world. The European Union has been one of the most important new markets for the Syrian citrus output but trading among the neighbors has to expand in ... -
Halmbasis- und Wurzelkrankheitserreger an Weizen (Trititcum aestivum L.) in Energiefruchtfolgen und Bedeutung des Halmbasisbefalls mit Fusarium culmorum (W. G. Smith) Sacc. und Fusarium graminearum (Schwabe) für die Mykotoxin-Kontamination der Pflanze
(2013-04-16)In the present study, the impact of energy crop rotations on stem basis and root pathogens of winter wheat (Triticum aestivum L.) was evaluated by means of a two-way factorial design in field trials conducted at two locations ... -
Genetic variation and inheritance of secondary seed dormancy in winter oilseed rape (Brassica napus L.)
(2012-11-29)Secondary seed dormancy in oilseed rape is a phenomenon that allows seeds to survive in the soil for many years without germination. Following soil cultivation, dormant seeds may germinate in subsequent years and are the ... -
Colonization of maize with Fusarium spp. and mycotoxin accumulation
(2012-01-06)Ear rot caused by Fusarium spp. is a serious disease of maize plants worldwide, which can be divided in two types: Red ear rot or Gibberella ear rot (GER), and Pink ear rot or Fusarium ear rot (FER). Apart from impairment ... -
Fusarium infection of bread wheat and subsequent mycotoxin contamination of milling products: Impact on quality parameters and composition of flour
(2011-12-15)Fusarium head blight (FHB) of wheat is a worldwide occurring disease reducing both grain yield and wheat quality. Grain quality is primarily degraded because of mycotoxins produced by several ... -
Brassica - Wildarten als neue genetische Ressource für die Rapszüchtung
(2011-12-14)The genetic base in the material which is available in rapeseed breeding is very limited in comparison with other crops such as wheat or maize which are used for a very long time by humans. ... -
Landtechnische Methoden zur Erfassung von Bodenverdichtungen
(2011-11-10)Sustainable use of arable soil is essential for world food security. Soil degradation by over-compaction is counteracting this goal. Long-term conventional tillage (plough) and heavy ... -
Studien zur Aminosäurenwirksamkeit beim Mastgeflügel unter spezifischer Betrachtung der schwefelhaltigen Aminosäuren
(2011-10-06)Based on a verified nonlinear N-utilization model (GEBHARDT 1966, Samadi und Liebert 2008), the objective of this investigation was to determine the amino acid efficiency of broiler chicken ... -
Breeding for a reduced glucosinolate content in the green mass of rapeseed to improve its suitability for biogas production
(2011-08-03)Brassica napus L., a plant that belongs to the Brassicaceae family is one of the main oil crops. Inside its seeds glucosinolates appear to be the main secondary glycoside, sugar containing ... -
Entmischung von kornähnlichen Epoxydharz-Markern in Weizen - Einfluss von Fördertechnik und Silolagerung
(2011-07-05)It is the special characteristics of bulk materials such as cereals which present major difficulties for present-day traceability systems (e.g. funnel flow in silos). Using grain-like markers ... -
