This article contains the results of the measurements of the flavonoids and phenolics content in the five Iris species (Iris pseudacorus, Iris crocea, Iris spuria, Iris orientalis and Iris ensata). Chosen plants are mostly grown as ornamental plants because of their colourful flowers, but biochemical research in recent year show that these species also contain in their leaves, roots and flowers some interesting chemical substances that can be used in medicine. In this experiment were used 5 years old plants which were grown on the experimental grounds of Horticulture Faculty in Lednice. For the research were used rhizomes, because the rhizomes are by most authors considered as the richest source of the secondary metabolites. We used lyophilized rhizomes – to measure the content of flavonoids and phenolics in the fresh matter. And air dried rhizomes, which were dried in room temperature (22 °C) for fifteen and fifty days. The results show that the content of the flavonoids in the fresh (lyophylized) rhizomes was highest in the rhizomes of Iris pseudacorus and lowest in the rootstocks of Iris orientalis. The highest phenolics content in the fresh (lyophylized) rhizomes was also in the Iris pseudacorus, the lowest in the Iris crocea.

Abstract The combined pollution, instead of single pollution, has become a widespread contamination phenomenon in aquatic environment. However, little information is now available about the joint effects of the combined pollution, especially co-existed pesticides and heavy metals, on aquatic plants. In the present study, using continuous excitation chlorophyll fluorescence parameters and the OJIP transient, comparisons of herbicide atrazine (ATZ) phytotoxicity on Iris pseudacorus between in the presence and absence of cadmium (Cd) were evaluated over an exposure period of three weeks under laboratory conditions. Results showed that both ATZ and Cd were toxic to I. pseudacorus. The ratio Fv/Fo, specific electron transport energy (ET0/RC) and photochemistry efficiency (PIabs and PItotal) of this emergent plant species at individual ATZ and Cd concentrations were significantly lower than those of the control. ATZ mainly inhibited electron transport beyond QA at PSII acceptor side as indicated by the sharp rise of the J-step level of fluorescence rise kinetics. A pronounced K-step and the loss of I-step due to the damage on the OEC and PSI also occurred when ATZ was at or above 1.0 mg·L− 1. In comparison to ATZ alone, ATZ combined with Cd resulted in a lower amplitude rise in J-step with apparent J-I and I-P phases; and significantly lower Fo with higher Fv/Fo, as well as greater ET0/RC with higher values of PIabs and PItotal. However, the adverse influences of ATZ combined with Cd on the above indicators were still significant as compared with the control. Therefore, the coexistence of Cd alleviated the individual phytotoxicities of ATZ, whereas combined pollution of ATZ and Cd still induced the decline in photosynthetic performance of I. pseudacorus, and its potential ecological impacts on the aquatic vegetation cannot be ignored. Our findings offer a better understanding of the joint effects of the pesticide and heavy metal on non-target aquatic plants, and provided valuable insights into the interaction of these pollutants in aquatic environment.
