Název v původním jazyce

Detection of photochemical processes in Antarctic lichen <i>Xanthoria elegans</i> using chlorophyll fluorescence imaging.

Popis výsledku v původním jazyce

<b>Introduction</b>: Within last two decades, chlorophyll fluorescence imaging has met increasing number of applications in photosynthesis research. Using the technique, heterogeneity of photochemical processes of photosynthesis might be visualized at various levels ranging from a single cell to a plant community. In lichens, the technique has been used several times in anatomic[1] and photosynthetic studies made under controlled laboratory conditions[2]. In the presented study, we used the technique inthe field in order to quantify photosynthetic processes in an epilithic crustose lichen species (Xanthoria elegans) as dependent on daily courses of in situ temperature, water availability and resulting hydration/dehydration of lichen thallus. <b>Material and Methods</b>: Heterogeneity of several photosynthetic chlorophyll (Chl) fluorescence parameters was measured on thalli of X. elegans attached to stone surfaces. Study plot was located at permanently deglaciated coastal areas of Gali
