Abstract:

The content of photosynthetic pigments in 30-day-old shoots of Scots pine grown under the influence of acetone extracts from lichens Hypogymnia physodes, Evernia prunastri, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula was studied. Extracts were on the surface of the substrate of seed germination and under it. With direct contact of sprouts of Pinus sylvestris with extracts from Hypogymnia physodes, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula, an increase in the content of chlorophylls and carotenoids, a change in the ratios of chlorophyll a: chlorophyll b

Flavoparmelia caperata L. Hale (common greenshield lichen) is an Ascomycete, foliose lichen usually growing on tree bark in most mesophytic-forested habitats in Romania. Lichen samples were collected from three stations in Romania (Craiova, Timișoara, Hoia-Baciu Forest, Cluj) and extracted in 96% ethanol. Both dry lichen tissue powder and extracts were analyzed by UV-Vis spectrophotometry for determining photosynthetic pigment concentrations (chlorophylls a and b and total carotenoids). Dry tissue samples had chlorophyll a concentrations of 95.12-109.59 mg/kg DW, chlorophyll b concentrations o
