Title: Effect of Ca~(2+) on the Mitosis and Growth of the Bulb Root of Allium L.
Abstract: The bulb of Allium L. was treated in solution in which there were different Ca(NO3)2 concentrations to study the effect of Ca2+ on the mitosis and growth of bulb root of Allium L. It was shown that: the mitosis index was higher at first and then lower (200mg/L maximum) with the increase of concentrations, the mitosis index was higher with the prolong of treatment time, but 400mg/L on the contrary. The rate of abnormal nucleus cells rose with the bigger of concentrations and lowered with the prolong of treatment time. The obvious characteristic was that more chromosome disintegration appeared in all concentrations all the time. This test results indicated that the effect of Ca2+ on the mitosis index and abnormal nucleus was different with heavy metal.
