The role of post-harvest supplementary light exposure for ripening and quality development of tomato fruit
(2020-11-23)
The major aim of the present work was to evaluate the optimal exposure time and effects of red light and short periods of daily ultraviolet (UV) on the post-harvest quality of green tomato fruit during ripening. The ...
Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)
Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ...
Synthese und Charakterisierung von funktionalen Lignin-basierten Polyurethan-Coatings aus unmodifiziertem und modifiziertem Kraft-Lignin
(2020-12-02)
Bedingt durch die zunehmende Rohstoffknappheit rückt die Suche nach alternativen, nachhaltigen Rohstoffen immer mehr in den Vordergrund. Im Hinblick auf effiziente chemische Verwertbarkeit bietet Lignin zahlreiche Vorteile ...
Iron isotope fractionation in arable soil and graminaceous crops
(2020-11-24)
Soils contain large quantities of Fe, however, the Fe-solubility is very low. Plants have developed two efficient strategies to secure Fe uptake from soil under Fe-deficient conditions: (i) the sequential acidification-r ...
Genetic and molecular analysis of drought stress adaptation in cultivated and wild barley
(2020-10-07)
Drought tolerance breeding is an integral part of modern-day agriculture for sustained crop production. In this study, we employed forward and reverse genetics tools to understand and improve drought stress adaptation in ...
Hyperspectral in-field sensing of foliar diseases of wheat
(2020-12-10)
The major aim of this work was to prove the suitability of hyperspectral sensors for the detection of foliar diseases of wheat under field conditions. Hyperspectral sensors, measurement protocols and analysis methods were ...
Interactive tillage & crop residue management effects on soil properties, crop nutrient uptake & yield in different weathered soils of West Africa: measurements, modelling & scenario simulations
(2020-04-22)
Sustainable crop production intensification in West Africa is hampered by constraints such as soil degradation, mainly due to excessive mining of soil nutrients, topsoil loss by surface runoff, and climatic factors like ...
Effect of cow’s metabolic status on the epigenome profile of oocytes and embryos
(2020-01-07)
In lactating cows, intensive genetic selection for improved milk production has been associated with reduced reproductive capacity, leading to increased early embryo loss. During post-calving lactation, the cow’s dietary ......
Einfluss des Stoffwechselstatus der Milchkuh auf das epigenetische Profil von Eizellen und Embryonen
Bei laktierenden Kühen führt eine intensive genetische Selektion auf eine verbesserte Milchproduktion ......

In vitro and in vivo assessment of lead toxicity on mammalian female reproduction and effect of antioxidants
(2020-03-17)
Heavy metals are among the environmental toxicants incurring great concern for human and animals because of their toxicity even at low concentrations. Lead (Pb) has been shown to induce severe and long lasting effects on ......
Acute impact of dietary pattern and walking on postprandial metabolism, attention, and mood in older adults with a cardiovascular disease risk phenotype
(2020-01-27)
Attenuating the postprandial stress response and its associated inflammatory and endothelial events through specific nutritional and lifestyle interventions seems to be a promising and important approach to decrease the ......
Die Abschwächung der postprandialen Stoffwechselreaktionen durch spezifische Ernährungs- und Lebensstilmaßnahmen stellt einen vielversprechenden und wichtigen Forschungsansatz dar, welcher insbesondere für Personen mit ......
