以10个品种萝卜(Raphanus sativus L.)为材料,测定萝卜不同品种不同部位的硝酸盐含量。结果表明,10个品种萝卜硝酸盐含量由高到低为春翡翠、潍县萝卜、特好吃水仙青、北京甜脆、德日2号、“791”、地黄缨、丰光、南鲁堡、新科791。10个品种除春翡翠是三级污染外,污染程度均为轻度或中度。真根部分的硝酸盐含量最高的是春翡翠,最低的是新科791；根颈部分硝酸盐含量最高的是春翡翠,最低的是南鲁堡；真根部分的硝酸盐含量要高于根颈(地黄缨除外)。韧皮部分的硝酸盐含量最高的是潍县萝卜,最低的是南鲁堡；木质部硝酸盐含量最高的是春翡翠,最低的是潍县萝卜。韧皮部的硝酸盐含量小于木质部(潍县萝卜和德日2号除外)。

Taking 10 radish varieties as materials the nitrate contents of different radish varieties and different parts of radish were studied. Results showed that the order from high to low nitrate contents of 10 radish varieties was spring jadeite>county turnip>especially delicious together narcissus green>Beijing sweet crisp> Germany and Japan No. 2>“791”>cherry>FengGuang>Nanlubao>Xinke 791. The highest nitrate content of radish variety was spring jadeite and the lowest was the Xinke 791. The degree of contamination of 9 radish varieties were mild and moderate, but the spring jadeite was serious. In the real root, the highest nitrate content of radish variety was spring jadeite and the lowest was the Xinke 791. In the root collar, the highest nitrate content of radish variety was spring jadeite and the lowest was the Nanlubao. The nitrate content of real root was higher than that of root collar. In the phloem, the highest nitrate content of radish variety was county turnip and the lowest was the Nanlubao. In the xylem, the highest nitrate content of radish variety was spring jadeite and the lowest was the county turnip. The nitrate content of phloem was higher than that of xylem.
