iron plaque and root system) of 21 rice varieties referred to three common rice cultivars (hybrid
conventional and glutinous) were studied through the field experiment in heavy metal polluted soils in the Dabao Mountain of Shaoguan
Guangdong province. The contents of the six experimental metals were higher in underground parts (root system) than in overground parts. Metal concentrations in different parts of rice showed significant differences among various rice cultivars (P<0.01). Conventional and glutinous rice had stronger ability to accumulate Fe
Cu
Zn
Pb and Cd than hybrid rice. Hybrid rice had stronger ability to accumulate As than the other two cultivars. Hybrid rice was more applicable to Fe
Cu
Pb
Zn and Cd polluted soils. Glutinous rice was more applicable to As polluted soils. The accumulation factors of Zn
Pb and As followed the order of root system>straw>rice hull>rice core. The accumulation factors of Fe
Cu and Cd followed the order of root system>straw>rice core>rice hull. The values of accumulation factors of Fe、Zn、Pb、As and Cd are higher in iron plaque than in root
with the exception of Cu. The ability to accumulate different metals by iron plaque was different
