“…This ratio is analysed as an indicator of the specificity of metal interaction with pigments, and its value depends on the type of metal and the growth stage of plants used in experiments (Myśliwa-Kurdziel and Strzałka 2002). After two-week copper treatment of 4-week-old spinach and oat plants, a slow rise in this ratio was observed (Baszyński et al 1988). Also nickel applied to etiolated bean during greening increased the Chl/Car ratio (Krupa et al 1993).…”

Key message Zn caused an increase of photosynthesis activity, carbohydrates and chlorophyll at the level 1-2.5 mM, while phenols revealed a continuous increase together with Zn increase in the medium. Abstract The aim of the present study was to determine the effect of various Zn application levels on some physiological, morphological and biochemical parameters of a hybrid Salix purpurea 9 triandra 9 viminalis 2. Plants were cultivated under control conditions with application of Zn in the range 0-5 mM. The effects on net photosynthesis rate (P N ), stomatal conductance (g s ), transpiration rate (E), intercellular CO 2 (C i ), chlorophyll a and b, carotenoids, growth, sugars and phenols were analysed. Our investigations confirmed a dual role of Zn, with benefits at the level 1-2.5 mM, and a decrease of measured photosynthesis activity, carbohydrates and chlorophyll below and above this range. Moreover, the decrease of these parameters at the highest Zn application did not reach the level of control plants. This means that this species may have further potential as an accumulator in polluted areas. However, phenols revealed a continuous increase together with Zn increase in the medium.

“…Furthermore, excess iron and copper induced oxidative stress in chloroplasts (Prasad and Strzalka, 1999). When the levels of ROS formed exceed the ROS-quenching ability of plants, peroxidation of chloroplast membranes would occur, which caused the further loss in pigment concentrations (Baszynski et al, 1988).…”

To elucidate effect of chemical reagents addition on growth of aquatic plants in restoration of aquatic ecosystem, Spirodela polyrrhiza (L.) Schleid was used to evaluate its physiological responses to excess iron (Fe 31 ) and copper (Cu 21 ) in the study. Results showed that accumulation of iron and copper both reached maximum at 100 mg L 21 iron or copper after 24 h short-term stress, but excess iron and copper caused plants necrosis or death and colonies disintegration as well as roots abscission at excess metal concentrations except for 1 mg L 21 iron. Significant differences in chlorophyll fluorescence (Fv/Fm) were observed at 1-100 mg L 21 iron or copper. The synthesis of chlorophyll and protein as well as carbohydrate and the uptake of phosphate and nitrogen were inhibited seriously by excess iron and copper. Proline content decreased with increasing iron or copper concentration, however, MDA content increased with increasing iron or copper concentration. # 2009 Wiley Periodicals, Inc.

“…As in former experiments, a decrease of photosynthetic affinity (c0 was caused by Cu (Rijstenbil and Wijnholds 1991, Rijstenbil et al in press). A competitive inhibition at metal binding sites in the photosystems, disturbance of photosynthetic electron transport, pigment breakdown and lipid peroxidation in chloroplasts have been described as damaging effects of the oxidative metal Cu (Sandmann and B6ger 1980;Baszynski et al 1988;De Vos et al 1989;De Vos and Schat 1991;Ahmed and Abdel-Basset 1992;Mishra et al 1993).…”

Oxidative stress induced by copper: defense and damage in the marine planktonic diatom Ditylum brightwellii, grown in continuous cultures with high and low zinc levels

et al. 1994

Light-limited cultures of the planktonic diatomDitylum brightwellii (West) Grunow were grown at 14%o salinity. Cells were subjected to oxidative stress induced by copper, in the presence of zinc. In two continuous cultures with total Zn levels of 40 and 140 nM, respectively, dissolved Cu levels were increased from 3 to 126 nM. This resulted in an increased Cu adsorption capacity of the cell walls, probably due to an increase of surface area and roughness. Sexual reproduction (auxospore formation) was accelerated but was considered as a non-specific stress response. Cu-induced oxidative stress was indicated by a decrease of reduced glutathione (GSH), and a removal of superoxide anions monitored as an increasing activity of superoxide dismutase (SOD). Although Zn has no oxidative potential per se, cell division rates and chlorophyll c contents were lower in the culture with high Zn levels. In both cultures, the pro-oxidant Cu caused a decrease of chlorophyll a, decreasing photosynthetic 02 evolution and cell devision rates, and a growing number of deformed and broken cells.
