THE EFFECT OF CENTRIFUGING ON THE POLARITY OF AN ALGA, GRIFFITHSIA BORNETIANA

VICTOR SCHECHTER 1

1 From the Department of Biology, College of the City of New York, and the Marine Biological Laboratory, Woods Hole, Mass.

Normal shoots appear upon Griffithsia cells at the point where heavier substances are concentrated by prolonged low speed centrifuging. In this way reversal of polarity may be produced anywhere along the plant axis. The possibility is suggested that the centrifuged substances are not directly determinative but act by stimulation.
