硝基苯胁迫对绿豆种子萌发及根尖细胞死亡的研究

Analysis of Germination and Cell Death of Mung Bean Induced by Nitrobenzene

以绿豆为实验材料,采用水培方法,研究不同浓度硝基苯对绿豆种子萌发及遗传损伤的影响.结果表明:绿豆种子发芽率、胚芽、胚根长度随着硝基苯浓度增加呈现下降趋势;硝基苯溶液会诱导绿豆根尖细胞死亡.

Using mung bean as the experimental material, using water culture method, the effect of different concentrations of nitrobenzene and genetic damage on Germination of mung bean seeds are studied in this paper. The results show that：the mung bean seed germination rate, embryo, radicle length increased with the concentration of nitrobenzene decreased ; nitrobenzene solution will induce cell death of root tip cells of mung bean.
