The occurrence of phosphatase activity that was dependent on Mg 2+ and K + and inhibited by diethylstilbestrol has been detected in unfertilized African violet ovules with the use of biochemical techniques. Since cation‐dependent phosphatase activity is believed to be involved in ion transport across cell membranes, these results are interpreted as lending indirect support to cytochemical evidence that suggests the innermost integumentary cells of African violet ovules are involved in active transport of solutes to the embryo sac.
