本试验以3 种不同浓度(20 ×10 - 6g/mL、30×10- 6g/mL和40 ×10- 6g/mL)DA- 6 处理甜菊叶片,不同时间( 处理后7d、14d 和21d) 取材,应用电镜技术观察细胞超微结构,发现处理后多种细胞器发生了不同程度的变化,并呈一定的浓度效应和时间效应。
In this experiment, the stevia leaves were treated with DA-6 at different concentrations (20 × 10-6g / mL, 30 × 10-6g / mL and 40 × 10-6g / mL) at different time (7d, 14d and 21d) The ultrastructure of the cells was observed by electron microscopy. The changes of various organelles were observed in different degrees after treatment, and showed some concentration effect and time effect.
