Unusual step(s) in the fast chlorophyll fluorescence induction in lichens.
Original language description
Introduction: Chlorophyll fluorescence induction (FI) measured with photosynthetic samples (higher plants, algae, cyanobacteria) within the first seconds of intensive light excitation (thousands of mmol photons m-2 s -1) reveals characteristic O-J-I-P transient. Parameters calculated from the transient are often used for detection of plant stress on the photosystem (PS) level (e.g. Strasser et al., 2000). We investigated the FI in lichen thalli and isolated lichen photobionts. Material and Methods: Thalli of foliose lichen species Lasallia pustulata and Umbilicaria hirsuta were collected in the field. The lichen photobiont strain, Trebouxia erici Ahmadjian, as a representative of green alga genus presented in both lichen species, was cultured in BBM3Nmedium at 20 C at the regime 16h light/8h dark. FI was measured using Plant Efficiency Analyser (Hansatech, Norfolk, UK). Intensity of red exciting light was about 6000 ľmol photons m-2 s-1.
