In this study we compared the cytological effect and chromosomal behavior of root meristems of Allium
cepa, induced by ZnO bulk and ZnO nanoparticles (NP). Four different concentrations of ZnO bulk and ZnO
nanoparticles (2.5, 5, 10 and 20 ppm) were used to treat the root tips at different durations (2, 4, and 6 hours). The influence of these treatm...

... physical characteristics and SEM picture of the ZnO nanoparticles according to the manufacturer's data are: purity, 99.5%, size 20 nm (SEM). ZnO bulk and ZnO engineered nanoparticles (50 mg/L) was suspended directly in 1000 ml of distilled water to prepare 50 ppm of both materials, then it was dispersed using ultrasonic vibrator (Eumax, ultrasonicator,UD50SH-2L, 50/60Hz) Figure 2. For 30 minutes [12]. ...

... However, Kumari et al. (2011), reported that ZnONPs reduced the MI in meristematic tissue of Allium cepa. Likewise, El-Ghamery et al. (2016), found out that ZnO at bulk and nanoparticles form caused reduction in MI of Allium cepa and induced different types of CA. All tested concentrations induced CA with slight differences. ...
