Název v původním jazyce

Annual variation of the steady-state chlorophyll fluorescence emission of evergreen plants in temperate zone

Popis výsledku v původním jazyce

Remotely sensed passive chlorophyll fluorescence emission has a potential to become one of the major global-scale reporter signals on vegetation performance and stress. In contrast to the actively probed parameters such as maximal (FM') or minimal (F-0')emission, the steady-state chlorophyll fluorescence, Chl-F-S, (FM' > Chl-FS > F-0') has not been adequately studied. Using fluorescence imaging of leaves, we explored the modulation of Chl-F-S by actinic irradiance and by temperature in laboratory, as well as the changes that occurred in three coniferous and broadleaf plant species grown in field. The experiments revealed that Chl-F-S is largely insensitive to the incident irradiance once this is above early morning or late evening levels. The characteristic, pre-noon measured Chl-F-S correlated positively with the CO2 assimilation rate when measured in field during the year. It was low and stable in the cold winter months and steeply increased with the spring onset. The high
