Photosystem II of barley seedlings under cadmium and lead stress

  title={Photosystem II of barley seedlings under cadmium and lead stress},
  author={Hazem M Kalaji and Tadeusz Loboda},
Chlorophyll a fluorescence measurements were carried out on two barley (Hordeum vulgare L.) cultivars Arabi Abiad and Arabi Aswad at 8 and 14 days after emergence to identify their early tolerance mechanism for heavy metals (25 and 50μM of cadmium and lead). Transient fluorescence curves (OJIP curves) and energy flux models showed different specific reactions of photosystem II (PSII) of each cultivar to each type of stress. After 7 days of lead stress application plants of cv. A. Aswad showed… CONTINUE READING
