以茎瘤芥主栽品种“涪杂2号”和“永安小叶”为试材,分析了茎瘤芥不同采收期瘤茎鲜重和总芥子油苷含量变化规律。研究表明:瘤茎鲜重与总芥子油苷含量变化与气温有关,茎瘤芥品种间的总芥子油苷含量受采收日期影响显著,各器官间也存在显著差异。分析提出,在重庆沿江500m以下的茎瘤芥产区,以2月中旬气温回升时采收最为适宜,瘤茎能够达到较高的总芥子油苷含量和实现丰产。
With the main cultivars of tumorous stem mustard “Fuza 2 ” and “Yong’an Xiaoye ” as test materials, the changes of tumorous stem fresh weight and total glucosinolate content in different harvesting periods were analyzed. The results showed that the fresh tuber weight and the total glucosinolate content were related to the air temperature. The total glucosinolate content of the tuberous mustard plants was significantly affected by the harvesting date, and there were also significant differences among the organs. The analysis suggested that in the region of tumorous stem mustard below 500m along the Yangtze River in Chongqing, it is most appropriate to recover when the temperature rises in mid-February, and the tumor stem can achieve higher total glucosinolate content and achieve high yield.
