Biometrische Auswertung von Rückkreuzungsserien in genetisch weiten Kreuzungen bei Sommergerste
Budewig, Stefanie (2007)Wildformen können zur Verbreiterung der genetischen Basis und zur Verbesserung qualitativer und vermutlich auch quantitativer Merkmale beitragen. Unerwünschte Eigenschaften der Wildformen zwingen den Züchter zu aufwendigen ... -
Characterisation of fitness parameters and population dynamics of Botrytis cinerea for the development of fungicide resistance management strategies in grapevine
Derpmann, Jürgen (2014-03-18)Gray mold caused by the fungus<i>Botrytis cinerea</i> is an economically important disease in grapevine. The pathogen has a high tendency to become resistant to frequently applied systemic fungicides. Only a few years after ... -
Charakterisierung des Bakterienspektrums der Kartoffel und dessen Potenzial zur biologischen Bekämpfung des Wurzelgallennematoden Meloidogyne incognita (Kofoid & White) Chitwood
Faupel, Annekathrin (2004)Pflanzenassoziierte Bakterien können zum Pflanzenwachstum und zur Pflanzengesundheit beitragen, jedoch ist bisher wenig über ihre Abundanz, Diversität und ihr antagonistisches Potenzial zur biologischen Kontrolle bodenbürtiger ... -
Comparison of DRIS and critical level approach for evaluating nutrition status of wheat in District Hyderabad, Pakistan
Akhter, Naheed (2012-03-07)Intensive cropping systems, improper use of fertilizers or no fertilizer application, and unreliable and poor quality of irrigation water have led to declining soil fertility in the district of Hyderabad, Pakistan. To date, ... -
Detection, identification, and quantification of fungal diseases of sugar beet leaves using imaging and non-imaging hyperspectral techniques
Mahlein, Anne-Katrin (2011-02-22)Plant diseases influence the optical properties of plants in different ways. Depending on the host pathogen system and disease specific symptoms, different regions of the reflectance spectrum are affected, resulting in ... -
Direct use of urine as fertilizer: potential risks of loading pharmaceuticals and hormones to field crops
Arias Escobar, Maria Alejandra (2019-04-11)Ecological sanitation or Ecosan is an alternative approach to avoid the disadvantages of conventional water-based sanitation systems. This approach, based on ecosystem functioning and the closure of material flow cycles, ... -
Effects of fungicides on physiological parameters and yield formation of wheat assessed by non-invasive sensors
Berdugo Agudelo, Carlos Andres (2014-05-15)Apart from fungicidal effects, some fungicide classes have been reported to induce physiological changes in crops such as increased tolerance to abiotic stress, delayed senescence of the photosynthetic leaf area and ... -
Einfluss unterschiedlicher Ozon-Immissionsmuster auf das Pathosystem Weizen-Mycosphaerella graminicola
Lamprecht, Sybille (2002)Weizenpflanzen wurden in Klimakammern bei unterschiedlichen Ozon-Immissionsmustern exponiert und der Einfluss der Schadgasbelastung auf das Pathosystem Weizen-<i> Mycosphaerella graminicola</i> untersucht. Die Wirkung eines ... -
Einfluss von Bodenhilfsstoffen auf die Wasserhaltekapazität bewässerter Böden
Wester, Jens (2018-12-05)Das Ziel der vorliegenden Dissertation war es, den Einfluss von Bodenhilfsstoffen auf die Wasserhaltekapazität (WHK) von Böden mit unterschiedlichen Bewässerungssystemen zu untersuchen. Um die Wirkung dieser Stoffe in der ... -
Experimental analysis and modelling of the rainfed rice cropping systems in West Africa
Worou, Omonlola Nadine (2012-07-18)There is a need to improve rice productivity to meet the increasing demand for rice in West Africa since it is acknowledged that existing rainfed rice cultivation practices deal with irregularities of climate like drought ... -
Genetic and physiological characterization of traits related to salinity tolerance in an advanced backcross population of wheat
Dadshani, Said Abdul Wali (2018-03-22)In large areas of the world wheat production is highly affected by soil salinity. Increasing the genetic variability of currently used wheat varieties is an efficient approach to overcome production losses and prevent food ... -
Genetic variation of traits related to salt stress response in Wheat (Triticum aestivum L.)
Oyiga, Benedict Chijioke (2017-01-24)Salinity is one of the most severe abiotic stresses perceived by plants, and is continuously increasing due to climatic change and poor irrigation management practices. It is currently affecting ~800 million hectares of ... -
The importance of the antagonistic potential in the management of populations of plant-parasitic nematodes in banana (Musa AAA) as influenced by agronomic factors
