Early detection of pathogens can significantly reduce yield losses and improve the quality of agricultural products. This study compares the efficiency of hyperspectral (HS) imaging and pulse amplitude modulation (PAM) fluorometry to detect pathogens in plants. Reflectance spectra, normalized indices, and fluorescence parameters were studied in healthy and infected areas of leaves.

The use of photoconversion coatings is a promising approach to improving the quality of light when growing plants in greenhouses in low light conditions. In this work, we studied the effect of fluoropolymer coatings, which produce photoconversion of UV-A radiation and violet light into blue and red light, on the growth and resistance to heat stress of tomato plants ( L.).

Article Synopsis
  • Chlorophyll fluorescence imaging was used to investigate how potato virus X (PVX) affects non-inoculated potato leaves.
  • Changes in chlorophyll fluorescence parameters, like photosystem II quantum yield and non-photochemical quenching (NPQ), were measured over time and correlated with the virus's spatial distribution.
  • Results indicated that chlorophyll fluorescence imaging can effectively detect viral infections before symptoms appear, with strong correlations between fluorescence parameters and virus presence.
