The effects of different treatments with sodium nitrate (SN), sorbic acid (SA) and propyl gallate (PG) on the cytology, root growth and total protein content of five concentrations of preservatives ranging from 1000 ppm to 2500 ppm for 4, 8 and 16 hours. The treatments inhibit the root growth and reduced the total protein content. The concentration at 2500 ppm applied for 15 days for root growth is more toxic than other and decrease in the percentage of protein content for 16 hours was highest. Cytological analysis showed inhibitory effect on cell division in the root tips of the test plant and caused a decrease in mitotic index values. Different abnormal mitotic figures were observed in all mitotic phases. Among these abnormalities were anaphase bridges, C-mitosis, lagging, stickiness, micronuclei and unequal distribution. The total percentage of abnormalities was highest in propyl gallate and lowest in sodium nitrate. All the treatments changed the frequency of mitotic phase as compared to with the control.
