工业大麻“云麻2号”对重金属Pb、 Cu和Cd富集特征的研究
Tolerance and Accumulation Capabilities of Heavy Metals Pb, Cu and Cd with Industrial Hemp Yunma 2
摘要
Abstract
In order to study the tolerance and accumulation abilities of industrial hemp under heavy metal environment,“Yunma 2” was planted and treated with artificial addition of Pb, Cu and Cd in pot experiment. The results showed that Pb2+ did not affect the normal growth of the plant under 600 mg/kg, and Pb2+ was mainly accumulated in root with 109. 05 mg/kg, only 2. 55 mg/kg in seeds. And the con-centration coefficient and the transfer coefficient of seed were 0 and 0. 02, respectively. Cu2+ was mainly concentrated in root, stem, leaf, seed and male flowers, however the least concentration was in fibers, which was from 3. 74~9. 24 mg/kg. Furthermore, concentration coefficient and transfer coefficient of fi-ber were less than 0. 20, Cd2+ could be strongly absorbed and accumulated by Yunma 2 when Cd2+ con-centration was 150 mg/kg. In addition, Cd2+ was mainly concentrated in root, stem, leaf and fiber, the concentration coefficients were very high ( >1 ) , especially in the root and fiber of male plants ( >2 ) . The results demonstrated that industrial hemp “Yunma 2” has good abilities to resist Pb2+ and accumu-late Cd2+.关键词
