摘要
以洋葱为试材,采用显微观察法,研究了不同浓度的K^+在不同处理时间下对洋葱鳞茎内表皮细胞凋亡的影响。结果表明:不同浓度的K^+处理洋葱鳞茎内表皮1h后出现细胞凋亡现象,随着K^+浓度的升高及处理时间的延长,细胞凋亡现象更明显,细胞凋亡率及细胞内丙二醛含量均上升。
Taking onion bulb as material,the effect of different concentration of potassium ion under different processing time on apoptosis in intraepidermal cells of onion bulb were studied by microscopy observation.The results showed that apoptosis generated in intraepidermal cells of onion bulb only after 1 hour by different concentration of potassium ion,with increased concentration and prolonged processing time of potassium ion,apoptosis phenomenon was more obvious,apoptosis rate and MDA content all went up.
