研究了9个烤烟品种对铜（Cu）、铅（Pb）、镉（Cd）、铬（Cr）、砷（As）和汞（Hg）6种重金属的吸收能力．研究结果表明：不同品种烤烟对6种重金属的吸收能力差异较大，据此可将重金属划分为3类：第1类是镉，不同品种烤烟对其吸收能力都较强，富集系数平均为3．751；第2类是汞，不同品种烤烟对其吸收能力都属中等，富集系数平均为0．735；第3类是铜、铅、砷、铬，不同品种烤烟对其吸收能力都较弱，富集系数平均为0．066．

Absorption ability of nine flue-cured tobacco varieties to six heavy metals of Cu,Pb,Cd,Cr,As and Hg was studied.The results showed that flue-cured tobacco varieties differed greatly in the absorption ability to the six heavy metals.Heavy metals could be divided into three categories according to the absorp-tion ability of flue-cured tobacco varieties to the six heavy metals.The first class,Cd,was enriched strongly by flue-cured tobacco varieties,the average enrichment factor was 3.751.The second class,Hg,was en-riched as a medium level by flue-cured tobacco varieties,the average enrichment factor was 0.735.The third class,including Cu,Pb,As and Cr,was enriched weakly,the average enrichment factor was 0.066.
