Abstract

The use of water polluted with heavy metals for irrigation can cause phytotoxic effects and affect crop production. An important step in mitigating possible negative effects is certainly a continuous monitoring of water quality, assessment of risk for crops by biotests, right choice of test plant and selection of parameters that reliably indicate the changes in the environment. The aim of this study was to assess indicators potential of germination energy (GE) and seed germination (G) of five cultivated plants (sorghum, cabbage, sunflower, beans and buckwheat) in detection of metal (Cr, Pb and Cd) presence in water. A filter paper method according to ISTA was used. Metals were applied in series of concentrations including maxmium allowable concentrations (MAC’s). Chromium significantly inhibited G and GE of sunflower seeds in treatments with 2000 µg/l, while lead caused such effects of GE and G of sorghum and sunflower in amounts exceeding 50 µg/l (two times less than MAC), and of cabbage and buckwheat at 200µg/l. Cadmium significantly inhibited GE and G of beans at 0.1 µg/l (100 fold less than MAC).The overall results suggest that GE and G can be considered as valid parameters for the detection of certain metal presence in water, in amounts exceeding MAC such as Pb (sorghum and sunflower seeds) and Cd (beans seeds).
