Název v původním jazyce

Changes of content of cytokinins in plants treated by polycyclic aromatic hydrocarbon

Popis výsledku v původním jazyce

The changes of phytohormone levels controlled by the respective hormone system are essential steps in acclimation of plants to the stress. The aim of this work was to evaluate the effect of polycyclic aromatic hydrocarbon fluoranthene (FLT) on the content of cytokinins in pea plants (Pisum sativum L., cv. Garde). Pea plants were cultivated in vitro in MS-medium enriched by IAA (0.1 mg/L) and BA (0.1 mg/L) and contaminated by FLT (0.1, 1 and 5 mg/L). After 21 days of cultivation the fresh and dry weight,content of photosynthetic pigments and the content of cytokinins was assessed. Fluorantene-caused changes in biomass production (increase of fresh weight and decrease of dry mass) and the increase of chlorophyll content could be related to the change inendogenous levels of cytokinins. The content of cytokinins (DHZR, iP, BA, BAR, mT a mTR) was increasing with increasing concentration of FLT in the environment. Lower concentration of FLT (0.1 mg/L) could inhibit the synthesis of cytokin
