Dehydration-induced responses of primary photosynthetic processes and spectral reflectance indices in Antarctic Nostoc commune
Original language description
In this study, we investigated the relationship between relative water content (RWC) of N. commune colonies recorded during gradual dehydration and (i) normalized difference vegetation index (NDVI), (ii) photochemical reflectance index (PRI), and (iii) primary photochemical processes of photosynthesis, effective quantum yield of photosynthetic processes (PhiPSII) in photosystem II particular. PRI increased from -0.05 to 0.02 with RWC decrease from 100% (full hydration) to 0% (dry state). NDVI showed somewhat curvilinear relationship with desiccation with minimum value of 0.25 found at 10% RWC. Negative effect of suprasaturation of N. commune colony with water on effective quantum yield (PhiPSII) was found at RWC range 80-100%. At the RWC range, PhiPSII reached only 50 % of maximum found at RWC of 30%.
