Towards optical detection of plasmopara viticola infection in the field
Popis výsledku v původním jazyce
Chlorophyll fluorescence, UV-induced fluorescence and reflectance signals of grapevine leaf tissue naturally infected by Plasmopara viticola were inspected in three susceptible grapevine cultivars (Cabernet Sauvignon, Pinot Blanc and Pinot Gris). Distribution of FV/FM parameter over the leaf was found to be effective to discriminate symptomatic and asymptomatic leaf tissue. Reduction of FV/FM parameter 25% was found in all infected leaf spots. Infected leaves also expressed significantly changed chlorophyll fluorescence induction kinetics expressing much slower electron transport rate on donor and acceptor site of photosystem II. Symptomatic leaves emitted high fluorescence signal under UV excitation 320nm, centered at 395nm, emanated mainly from highly fluorescent compound 2,4,6-trihydroxyphenanthrene-2-O- glucoside. Increase of this compound was found in all inspected grapevine varieties, while its concentration was strongly dependent on resveratrol concentration. Concentration of tr
