When kinetin (1 mg/liter) is added to hay infusion medium, the generation time of Paramecium caudatum is shortened immediately upon transfer of the protozoa from stock to isolation culture. Kinetin is particularly effective when culture conditions are suboptimal, perhaps because it substitutes for or supplies some factor which becomes limiting after transfer.
