Abstract

China is one of the countries with serious pollution of heavy metals in cultivated land, which caused much loss to crop yield and quality, especially to sweet maize. In order to analyze dry weight of shoots, roots and spikes and the enrichment characteristics of Pb and Cd of 10 sweet maize inbred lines under moderate Pb, Cd and compound stress of Pb and Cd stress, a pot culture was conducted at room temperature in green house. The result indicates that the Pb and Cd accumulation in sweet maizes shows a trend like roots>leaves>grains. The influence of stress type on dry and fresh weight is as compound stress>Cd stress>Pb stress. The dry and fresh weight affected by stress shows a trend as grains>leaves>roots. According to the yield of grains, SW10 (relative coefficient 0.964) and SW6 (relative coefficient 0.931) was selected as the Pb high tolerance inbred line and Cd high tolerance inbred lines respectively, and the grains' coefficients of fresh weight under compound stress are 0.706 and 0.751 respectively. 3 of 10 inbred lines are screened out, whose grains Cd accumulations are under 0.1mg under Cd stress. 2 of 10 inbred lines are screened out, whose grains Pb accumulations are under 0.1mg under compound stress and 3 of 10 inbred lines are screened out, whose grains Cd accumulations are under 0.1mg under compound stress. The inbred line SW3 is the only material whose Pb and Cd accumulations are neither exceeding the standard. Above research provides astrategy of sweet maize breeding materials under heavy metal stress.
