不同辣椒品种镉吸收与转运的差异
Differences between Cadmium Uptake and Translocation among Different Pepper Varieties
摘要
Abstract
Hydroponic experiment was conducted to study the effect of different Cd levels(0、20、40 mg·L-1)on dry weight,Cd concentration of root,stem,leaf and Cd transport from root to shoot between 2 pepper varieties(PE3 and PE30). The results showed that dry weight and Cd content increased with the increase of Cd level(CCd≤40 mg·L-1),and the tolerance to Cd of different pepper varieties was also different. Under the same Cd treatment,Cd concentrations of 2 pepper varieties were in the order of root>stem>leaf. Significant differences in Cd accumulation and translocation were observed between 2 pepper varieties. Cd concentration in the stems and leaves,and Cd translocation coefficient and shoot Cd enrichment coefficient of PE30 were higher, which might lead to the risk of excessive Cd in fruit. Root was the primary tissue of Cd accumulation in PE3,and the ability to transport Cd from root to shoot was poorer,so PE3 could be planted in Cd lightly contaminated soil.关键词
