Multitemporal Chlorophyll Mapping in Pome Fruit Orchards from Remotely Piloted Aircraft Systems
Remote Sensing, 2019 Early and precise spatio-temporal monitoring of tree vitality is key for steering management decisions in pome fruit orchards. Spaceborne remote sensing instruments face a tradeoff between spatial and spectral resolution, while manned aircraft sensor ...

Chlorophyll fluorescence analysis: a guide to good practice and understanding some new applications.
Journal of Experimental Botany, 2013 Chlorophyll fluorescence is a non-invasive measurement of photosystem II (PSII) activity and is a commonly used technique in plant physiology. The sensitivity of PSII activity to abiotic and biotic factors has made this a key technique not only for ...

Measuring Leaf Chlorophyll Concentration from Its Color: A Way in Monitoring Environment Change to Plantations [PDF]
AIP Conference Proceedings 1554 (1), 210-213 (2013), 2013 Leaf colors of a plant can be used to identify stress level due to its adaptation to environmental change. For most leaves green-related colors are sourced from chlorophyll a and b. Chlorophyll concentration is normally measured using a spectrophotometer in laboratory.

Light Energy Driven Nanocommunications with FRET in Photosynthetic Systems [PDF]
IEEE Access, vol. 9, pp. 44490-44501, 2021, 2020 Chlorophylls and carotenoids, key components of photosynthetic systems, are proposed for molecular communications at the nanoscale with the mechanism of resonance energy transfer. Both types of pigments are introduced focusing on their exceptional properties like energy harvesting, ultra-low energy consumption during transmissions, picoseconds delays ...

Can Reduced Irrigation Mitigate Ozone Impacts on an Ozone-Sensitive African Wheat Variety?
Plants, 2019 Ground-level ozone (O3) pollution is known to adversely affect the production of O3-sensitive crops such as wheat. The magnitude of impact is dependent on the accumulated stomatal flux of O3 into the leaves.
