TY - CONF ID - 609085 AU - Váňová, Lucie - Kummerová, Marie PY - 2005 TI - Photoinduced change of toxicity of fluoranthene on pea plants (Pisum sativum L.) SN - 807157905X KW - pea plant (Pisum sativum L.) KW - PAH KW - fluoranthene KW - photosynthesis KW - chlorophyll fluorescence KW - photomodification N2 - The task was to observe the influence of increased concentration (0,1, 1, 10 mg.l-1) of intact (FLT) and photomodified fluoranthene (phFLT) and a time of exposition (12, 24 and 48 h) to chosen parameters of chlorophyll fluorescence (F0, FV/FM, qN, PhiII) of a pea plant (Pisum sativum L.) on organ and subcellular levels was observed. The obtained results demonstrated significant influence on primary processes of photosynthesis: - the significant changes in the chlorophyll fluorescence parameters: the inhibition FV/FM and PhiII and the stimulation F0 and qN - by the highest applied concentration (10 mg.l-1) FLT and phFLT after 12 h of exposition. More sensitive response for a presence of FLT and phFLT in environment was demonstrated by their application on the separated leaves. By the short time exposition (48 h) was not demonstrated the higher phytotoxicity of phFLT. ER -
