Analyzing photosynthetic performance in natural fluctuating environment using light-induced fluorescence transient (LIFT) method in high-throughput
Keller, Beat (2018-12-04)In the present work, the knowledge gap concerning the interaction of photosynthesis with its fluctuating environment was filled by acquiring over one million chlorophyll fluorescence measurements in semi-field and field ... -
Breeding progress for drought tolerance and nitrogen use efficiency in winter wheat (Triticum aestivum L.)
Koua, Ahossi Patrice (2022-03-28)Drought is the major abiotic stress factor limiting agricultural production in arid, semi-arid as well as in temperate regions around the world, whereas nitrogen (N) is one of the most important nutrients for crop production. ... -
Combining Fluorescence and Reflectance to Quantify Dynamics in Photosynthetic Regulation
Acebron, Kelvin (2021-12-14)Photosynthesis in the field is anything but steady-state. Because environment is changing, understanding plant’s photosynthetic activity <em>in situ</em> is challenging. Measurement of solar-induced fluorescence (SIF), ... -
Decision analysis and hyperspectral imaging to support farmers in ornamental heather production
Rütt, Marius Andreas (2022-02-02)Ornamental Heather (<em>Calluna vulgaris</em>) is an important crop for the farmers of Germany’s Lower Rhine region. These farmers produce more than 78% of the ornamental heather in Germany. Successful production of this ... -
Genotype-dependent phenotypic variation for agronomic traits, seed composition, and root architecture of Chilean Quinoa (Chenopodium quinoa Willd.)
Pandya, Archis K. (2023-11-20)Today, climate change is one of the biggest challenges facing agriculture practices, and it has significant implications for the sustainable provision of nutritious food in sufficient amounts. To meet such challenges, there ... -
High-Throughput Phenotyping of Photosynthesis Traits in Durum Wheat Under Drought Stress Using Light-Induced Fluorescence Transients
Zendonadi dos Santos, Nícolas (2022-03-24)Agriculture in the twenty-first century faces the double challenge of feeding a growing population in a changing climate. Food security will increasingly rely on the active release of stable high-yielding cultivars with ... -
Investigating the Potential of UAV-Based Low-Cost Camera Imagery for Measuring Biophysical Variables in Maize
Tewes, Andreas (2018-11-27)The potential for improved crop productivity is readily investigated in agronomic field experiments. Frequent measurements of biophysical crop variables are necessary to allow for confident statements on crop performance. ... -
Measuring and scaling environmentally induced dynamics of solar-induced chlorophyll fluorescence (SIF) from the ground to the aircraft
Quiros Vargas, Juan Jose (2023-11-11)Chlorophyll fluorescence is the absorbed photosynthetically active radiation (PAR) re-emitted as a faint red glow when the photosynthetic apparatus is not able to run photochemistry. This relation that Chlorophyll fluorescence ... -
Proline mediated drought tolerance of selected barley (Hordeum vulgare L.) introgression lines and characterization of in vivo spike development
Frimpong, Felix (2022-08-31)The potential yield of barley is likely to decrease in the future due to the prevalence of drought stress in many world regions. In our study, drought stress affected phenology, biomass and other growth traits, and seed ... -
Role of root plasticity in response to soil compaction in sorghum
Correa Reyes, José Eduardo (2022-06-17)Compacted soils limit crop production and affect millions of hectares of agricultural land globally. Plants vary in tolerance to soil compaction and roots express various plastic responses. Unfortunately, the importance ... -
Root and shoot phenotypic traits and their expression in response to sowing density in spring barley (Hordeum vulgare)
Hecht, Vera Lisa (2019-11-12)Much is known about plant performance under controlled conditions and much about performance under field conditions as well as on single plants and populations. The extent, however, to which the variability of traits, ... -
Suitability of non-destructive sensors for monitoring physiological and biochemical responses of tomato leaves and fruits to abiotic stresses
Groher, Tanja (2019-05-02)The major aim of the present work was to proof the suitability of chlorophyll fluorescence-based indices to non-destructively monitor and predict changes in the content of plant compounds in response to abiotic stresses. ... -
Towards a more efficient and sustainable fertilization through recycling phosphorus as struvite
Robles-Aguilar, Ana Alejandra (2018-11-08)Food and water security are dependent on the sustainable use of phosphorus (P). However, there is no single solution for achieving a phosphorus-secure future. P recovered and recycled from current waste streams (like manure) ... -
UAV remote sensing for the spatial differentiated assessment of plant traits based on multispectral images
Wilke, Norman (2023-01-09)Rising global temperatures, carbon dioxide (CO<sub>2</sub>) concentration, and the occurrence of extreme weather events are constantly changing the environmental conditions for crop productivity. Identifying climate-adapted ...
