| Abstract: | Garlic bulbs were treated with solutions containing Zn2+, Ca2+ and Zn2+ plus Ca2+ respectively and the results showed that Ca2+can relieve the Zn2+ toxicity, increasing the percentage of dividing cells greatly, lowing the percentage of abnormal cells. At the same time it was found that the growth of root tips was enhanced by Ca2+ addition. The general trend in the effects of different treatments on the root growth and percentage of dividing cells was Ca2+>Zn2++Ca2+>Zn2+. The trend for the percentage of abnormal cells was Ca2+>Zn2+>Zn2++Ca2+for the same treatments. |
