Das Bioenergetische Profil präimplantativer Rinderembryonen - Spezifische Effekte der In vitro Kultivierung und der Kryokonservierung
(2024-10-08)Ein beständiges Thema in der In-vitro Produktion (IVP) von Rinderembryonen ist die beeinträchtigte Entwicklungskompetenz. Diese lässt sich durch eine verminderte Kryotaug-lichkeit und geringeren Implantationsraten nachweisen ... -
Effects of mixing multiple spring wheat and faba bean cultivars in variable densities and environments
(2024-10-02)Intercropping, the practice of cultivating two or more crop species together, is widely recognized as a sustainable crop production system. This approach is valued for its ability to enhance production, stabilize crop ... -
Assessing the compatibility of genotypes in the rice—Magnaporthe oryzae interaction by hyperspectral imaging
(2024-10-01)The optical properties of plants are valuable indicators of their health and can be used to detect, monitor, and characterize both biotic and abiotic stresses. Spectral techniques like hyperspectral imaging (HSI), have ... -
Global and experimental evidence on the adoption of innovations and robotics for sustainable crop production
(2024-09-26)Agricultural innovations in general and smart farming technologies (SFT) in particular, can mitigate the negative environmental impacts and risk inherent to modern agricultural practices while increasing productivity and ... -
Prokaryotic colonization of soil during early-stage aggregation and of soil microaggregates
(2024-09-25)Soil is a complex mixture of minerals, gas, water and organic materials that assemble into aggregates and define pore spaces, therewith providing connective and isolated habitats for microorganisms. The soil microorganisms ... -
Grape phenolic maturity: Dynamics of polyphenol-polysaccharide interactions and the impact of grape seeds
(2024-09-24)Red wines contain various polyphenols that significantly impact their sensorial characteristics, making polyphenol extraction crucial for winemakers. Polyphenols are extracted from grape berries during maceration and ... -
Quantitative evaluation of ruminal nutrient degradation using in situ and in vitro methods
(2024-09-06)Quantitative evaluation of ruminal nutrient degradation using <em>in situ</em> and <em>in vitro</em> methods Studies on ruminally cannulated animals are expensive and time consuming. Furthermore they are limited to a few ... -
Towards Sustainable Water Use in the Indus River Basin: Assessing Groundwater Dynamics, Environmental Flows, associated Controlling Factors and Management Options
(2024-09-05)The dissertation highlights the need to release enough discharge as EFs to conserve ecosystems and found that the Chenab, Ravi, and Sutlej Rivers of IRB are particularly vulnerable to the ecosystem as the estimated EFs ... -
Plant mucilage effects on rhizosheath formation
(2024-08-28)The formation of rhizosheaths, protective layers encasing plant roots, involves various factors, including mucilage presence. Yet, the specific impact of mucilage concentration on rhizosheath growth remains unexplored. ... -
Recreating genomically stable rapeseed
(2024-08-15)Rapeseed (<em>Brassica napus</em>, AACC) is a young allotetraploid species formed by the hybridization of <em>Brassica rapa</em> (AA) and <em>Brassica oleracea</em> (CC). The genetic diversity of rapeseed is limited as a ... -
Imaging spatial and temporal soil water content variations of the soil-plant continuum using ground penetrating radar
(2024-07-23)The soil-plant continuum regulates a wide range of processes, which are crucial for plant performance, such as root water and nutrient uptake and the spatio-temporal distribution of soil water. Especially for agricultural ... -
The Role of Lipids in the Formation of Beneficial Interactions Between Plant Roots and Soil Microbiota under Heat Stress
(2024-07-15)Climate change, which is characterized by the rise of global atmospheric temperatures known as global warming, has serious detrimental effects on crop production because of the direct influence of elevated temperature on ... -
