V=volume of the flavouring solution, m=mass (on average 0.2 kg) of onion bulb used, TCII=total number of interphase and undifferentiated cells, P=prophase, M=metaphase, A=anaphase, T=telophase, TCD=total number of dividing cells, MI=mitotic index. Within the same treatment, MI values followed by different letters are significantly different at 5% by χ² test
