摘要
通过水培实验 ,对我国北方 18个小麦品种的耐镉能力进行了对比研究 ,结果发现 ,不同小麦品系的耐镉能力具有一定的差异 ,从而提出了半衰减浓度作为镉胁迫的生理指标。表 3,参 5。
Through aquatic culture method,the differences of tolerant abilities to cadmium among 18 winter wheat varieties in north China were compared The results showed that different winter wheat with different tolerant ability to cadmium.Then we introduced the conception of half-growth concentration as an index of tolerant ability of winter wheat in the experiment.The higher of half-growth concetration of winter wheat varieties the higher of the tolerant ability to cadmium.There were three winter wheat varieties whose half-growth concentration is >1 mg/kg,other's <1 mg/kg.
