Effect of sodium fluoride treatments on the mitotic cycle of root-tip cells in jack pine seedlings

Abstract

Fluoride-induced changes in the mitotic cycle were studied in root-tip cells of jack pine (Pinus banksiana Lamb.) seedlings using the metaphase accumulation method. Sodium fluoride treatments resulted in lengthening of the mitotic cycle. This was due to an increase in the duration of interphase. The duration of mitosis and individual mitotic phases was not affected by the treatments.
