摘　　要：通过低浓度铅(300mg·kg-1)处理对不同黄/红麻品种生物产量、富集能力和转运能力进行研究。结果表明:铅处理对不同黄/红麻品种生物产量有明显影响,初步筛选出4个铅耐受黄/红麻品种。黄/红麻不同部位铅累积:根部>茎部>嫩茎叶;铅吸收量:根部>嫩茎叶>茎部。黄/红麻不同品种铅富集系数:红麻闽红964>光钝感红麻,黄麻闽黄1号>黄麻179>埃及黄麻>闽黄麻1号;铅转运系数:闽黄1号和光钝感红麻转运系数分别达到0.76和0.82。Through low concentration lead （ 300 mg · kg^- 1） treatment, the biological yield, enrichment ability and transportation ability of different jute and kenaf varieties were studied. The results showed that lead treatment had obvious effects on the biological yield of different jute and kenaf varieties, and 4 lead-tolerant jute and kenaf varieties were preliminarily screened out. Lead accumulation： roots〉 stems〉 tender stems and leaves; Lead absorption： root〉tender stem 〉 stem; Lead enrichment coefficient： ＇ Minhong 964＇ 〉 light insensitive kenaf, 〉 Minhuang No. 1＇〉jute 179〉Egyptian jute〉＇Minhuang No. 1＇ The transport coefficients of ＇Minhuang No. 1 insensitive kenaf could reach 0.76 and 0.82 respectively.
