Abstract:
Mitosis in the root-tips of Hydrocleis nymphoides occurs throughout day and night with interphase and prophase always predominating and showing a negative correlation with each other. Except for interphase, all the stages are generally more frequent during the day. High temperatures appear to boost interphase and prophase stages whilst low temperatures boost metaphase, anaphase and telophase. © 1975, Japan Mendel Society, International Society of Cytology.
