Glucosinolate composition was determined in wild radish accessions from eight states in the northeastern and southern United States to determine the variability of production among accessions. Glucosinolates were evaluated from roots, leaves, flowers, primary, and secondary branches. Seventeen glucosinolates were identified, with glucoerucin, glucoraphenin, glucobrassicin, and gluconasturtiin contributing 90% to 100% of the total glucosinolates. Flowers contained the highest glucosinolate concentrations, 12.07 to 55.36 μmol/g, but flowers contributed only 5.3 to 21.3% to the total glucosinolates. Of the eight accessions, the Mississippi accession produced significantly higher levels of total glucosinolates and glucosinolates which can be degraded to isothiocyanates per plant, totals of 618.97 and 563.53 μmol/plant, respectively. Total plant biomass did not differ between accessions indicating a difference in the ability of the Mississippi accession to produce glucosinolates. Further studies are needed to determine if this accession would consistently produce higher glucosinolate levels under different environmental conditions.
从美国东北部和南部的八个州的野生萝卜中确定了硫代葡萄糖苷的组成，以确定不同品种之间的产量差异。从根、叶、花、一级和二级分枝中评估了硫代葡萄糖苷。鉴定出了 17 种硫代葡萄糖苷，其中葡萄糖苷、葡萄糖异硫氰酸盐、葡萄糖异硫氰酸盐和葡萄糖异硫氰酸盐占总硫代葡萄糖苷的 90%至 100%。花中含有最高的硫代葡萄糖苷浓度，为 12.07 至 55.36 μmol/g，但仅占总硫代葡萄糖苷的 5.3%至 21.3%。在这 8 个品种中，密西西比州的品种总硫代葡萄糖苷和可降解为异硫氰酸盐的硫代葡萄糖苷的产量明显更高，分别为 618.97 和 563.53 μmol/株。不同品种之间的总植物生物量没有差异，表明密西西比州品种产生硫代葡萄糖苷的能力不同。需要进一步研究以确定该品种在不同环境条件下是否会持续产生更高水平的硫代葡萄糖苷。
