Response of grapevine leaves to Plasmopara viticola infection by means of measurement of reflectance and fluorescence signals.
Popis výsledku v původním jazyce
Response of grapevine leaf tissue naturally infected by Plasmopara viticola in field was measured by means of chlorophyll fluorescence and reflectance signals. Three susceptible grapevine varieties (Cabernet Sauvignon, Pinot Blanc and Pinot Gris) were used in this study. Since the infection impairs photosynthetic activity, distribution of FV/FM parameter (maximum quantum yield of Photosystem II) over the leaf was effective to discriminate healthy and naturally infected leaf tissue. FV/FM was reduced ~ 25% in all infected leaf parts. Infected leaf spots expressed significantly altered chlorophyll fluorescence induction kinetics expressing much slower electron transport rate both on donor and acceptor site of PSII. Vegetation reflectance indices followedthe variations in pigment content after the fungal infection. Among others, R750/R700 (R2 = 0.877) and CRI (R2 = 0.735) were the most potent to follow changes in chlorophylls and carotenoids contents, respectively. Infected leaf tissue e
