Potential of chlorophyll fluorescence and VIS/NIR spectroscopy measurement use for the detection of nitrogen content and disease infection of apple leaves

Original language description

A possibility of using spectral methods for determining a nutritional status and detecting pathogens in apple-tree cvs. Jonagold and Idared was verified in experiments in 2007 až 2010. Treatments differed in the fertilizer or fungicide dose. Leaf sampleswere collected to determine nitrogen content and to measure spectral reflectance (spectrophotometer Avantes USB 2000) and chlorophyll fluorescence imaging (FluorCam). Results of the measurements were correlated to leaf analyses for nitrogen content in dry matter. At the same time, a health status (the occurrence of fungal pathogens Venturia inaequalis and Podosphaera leucotricha) was assessed and changes of photochemical efficiency of infected leaves were evaluated. The parameters providing the best description of differences in the photosynthetic activity of leaves depending on treatments (parameters Fv/Fm and GENTY) were selected. The values of correlation coefficients of Fv/Fm and GENTY depending on fertilization treatments were as
