Abstract:
A solution culture experiment was carried out to examine the genotypic differences of barley in the uptake/accumulation of Cd and some mineral elements, plant development and biomass accumulation under different Cd levels. The results showed that the plant height, leaf number, SPAD value and biomass accumulation of shoot/root were significantly reduced in the plant grown in 1 mumol.L-1 Cd nutrient solution compared to control, and the absorption of Zn, Mn and Cu was strictly retarded. There was a highly significant difference in the reduction of these growth parameters among cultivars. Mimai 114 and Zhenong 1 showed the least reduction, suggesting its high tolerance to Cd toxicity, while Wumaoliuling with the greatest reduction. Significant cultivar difference in Cd concentration/accumulation was also found. Zhenong 1 contained the highest Cd concentration in plant tissue, while Mimai 114 contained the lowest Cd concentration. A significantly negative correlation between biomass accumulation and Cd concentration/accumulation of shoot and Cd concentration of root was found, while no significant relationship with root Cd accumulation.
