ABSTRACT

Lead is among the most contaminant metals in ecosystem and has different effects on anatomical and morphological characters of different plant species. Matricaria chamomilla is an important medicinal plant which contains 120 chemical compositions. In this research, the effects of lead on production of apigenin as a significant medicinal substance were studied. Furthermore, structural changes of M. chamomilla were studied in different stages of development by electron and optic microscopes. So the plants in first stage of development, were transplanted to hydroponic culture with five-treatment design of 0, 60, 120, 180, 240 μM Pb. The plants under treatment were harvested in first stage of development, as well as in shooting and flowering stages for measurement of Pb absorption. According to this study, morphological changes were not visually observed during the treatment process in different stages; nevertheless, reduction in total biomass was detected in different stages compared to control plants. The results of SEM study of leaf indicated structural changes in stomata and epicuticular waxes in different stages. Also in anatomical studies we noticed several changes in cross section of leaf, stem and root. The obtained results indicated that in different stages, Pb accumulation in roots and shoots has increased under Pb stress during various stage of development. Moreover, Pb stress has no effect on apigenin content. Therefore, M. chamomilla is an excluder species which is tolerant to Pb stress.
