镉,铁在烟草中的相互作用及对烟草品质的影响

在镉的作用下，烟草对铁的吸收受到了抑制；在铁的作用下，镉的吸收有所增加。镉促使烟草中氨的含量和蛋白质的含量升高，但都低于对照组中的氮和蛋白质的含量；当铁的浓度超过正常范围时，它对烟草的氮和蛋白质的含量有较强的抑制作用。锅和铁对烟草中烟碱的含量均有不利影响，尤其是在镉铁共同存在时更是如此．鉴于镉污染区常伴随有较高浓度的铁。从而建议尽可能在镉污染区内减少对烟草的种植。本文还对镉铁之间的相互作用进行了讨论

Interactions between Cadmium and Iron and Their Effects on the Qudkty of TObacco

The uptake of Fe decreased in tobacco treated with Cd;the uptake of Cdwas enhanced in tobacco treated with Fe. The contents ofnitrogen and protein in the leaf oftobacco went up below that of in control under the treatment of Cd;and the content ofnitrogen and protein decreased when the concentration of Fe was far above the normaldose level.Cd and Fe gave no beneficial effects on the content of nicotine,especially in thecondition of coexesting pollution. It is suggested that the plantation of tobacco be got ridof the area contaminated with Cd often accompanied with high dose Fe. The interactionsbetween Cd and Fe was also discussed in this paper.
