| 摘 要： | 低危害烟叶的开发研究一直是国内外烟草研究的热点。大量研究表明,土壤镉(Cd)污染是影响我国烟草品质安全性的主要因素之一。烟草属于易累积Cd的作物之一,Cd污染胁迫不仅影响烟草的生理过程,同时也会降低烟叶的品质。笔者针对目前国内外对Cd在土壤-烟草系统中的迁移、转化规律及其影响因素进行了综述,并对降低烟草Cd吸收的主要措施及相关研究进行了展望。

| Abstract: | Cultivation of low-hazard-tobacco(Nicotiana tabacum L.) has been focus of research on tobacco sciences.Recently,numerous studies indicated that cadmium accumulation by tobacco in polluted soils was becoming one of the main factors that affecting the tobacco quality.Cadmium was readily accumulated by crops such as tobacco in soils,and the cadmium stress in soils could not only affect the physiological process,but also reduced tobacco's quality.The mechanisms governing the transport,accumulation,and compartme... |
