Different mitosis stages of Iraqi wheat “Behoth 22” i.e. (1) Interphase, (2) normal prophase, (3) Metaphase with polar view, (4) normal anaphase, (5–8) showing the effect of different Nano-amino zinc concentrations on chromosomal aberrations i.e. 50 ppm after 8 hrs (5) fragment, C-phase, ring chromosome, distributed chromosome and deletion; 100 ppm after 8 hrs (6) showing irregular metaphase, lagging chromosome, distributed chromosome, stickiness and c-phase; 150 ppm after 8 hrs (7–8) showing undistributed anaphase, erosion, gab chromosome, ring chromosome, fragment and stickiness, (9) showing the chromosomal aberrations under 50 ppm after 16 hrs, were abnormal metaphase (sticky and uncoiling); 100 ppm after 16 hrs, (10) showing irregular anaphase (fragments, lagging, ring, C-phase, distributed chromosome and sticky), 150 ppm after 16 hrs, (11–12) showing abnormal metaphase (sticky, deletion, distributed chromosome, gap chromosome and ring), from (13–18) showing chromosomal aberrations under 50 ppm after 24 hrs were abnormal metaphase and sticky ends with lagging chromosome (13–15) showing irregular metaphase and anaphase with sticky and erosion, (16–18) showing irregular anaphase with sticky, bridge, fragments, erosions, and multinuclei under 100 ppm after 24 hrs (19–23) showing the effect under 150 ppm after 24 hrs of treatments were multinuclei, fragments, erosions, irregular metaphase and anaphase with sticky and erosion and (23) showing explosion in cell wall that cussed chromatids deletion, and ghost cell.
