| 摘 要： | 目的]研究重金属镉（Cd）对香蕉幼苗生理生化指标的影响。方法]以砖红壤为供试土壤,以巴西香蕉为试验植物,采用盆栽模拟试验的方法研究了土壤外源重金属Cd对香蕉幼苗叶片生理生化指标的影响。结果]在试验浓度范围内,不同浓度Cd处理对香蕉幼苗叶片叶绿素含量的影响不明显;Cd对维生素C含量的影响表现为低促高抑,当Cd处理浓度为3 mg/kg时维生素C含量达到最大值,以后随Cd处理浓度增加而明显下降,且低于对照;脯氨酸和过氧化物酶（POD）活性在Cd处理下均呈现先升高后降低的趋势,均在Cd浓度为15 mg/kg时达到高峰,且各处理均高于对照。结论]为海南香蕉生产质量安全提供了理论依据。

| Abstract: | Objective] The aim was to study effects of cadmium on physiological and biochemical indexes of banana seedlings.Method] Effects of cadmium in latosol on physiological and biochemical indexes of Brazilian banana seedlings were studied by pot experiments.Result] Within the concentration range of the experiment,as cadmium concentration increased,the chlorophyll content of banana leaf didn't change significantly.The low concentrations(0-3 mg/kg) of cadmium could increased the content of vitamin C,while the h... |
