THE BLOCKING OF EXCYSTMENT REACTIONS OF COLPODA DUODENARIA BY ABSENCE OF OXYGEN

MORDEN G. BROWN 1

1 From the School of Biological Sciences, Stanford University

1. Excystment time is independent of oxygen tension down to 15 mm. Hg.

2. Excystment is blocked by very low oxygen tensions. This block is at a developmental stage between the excystment period dependent on concentration of the excystment solution and the periods independent of concentration.

3. The excystment process may be divided into four physiological periods characterized by the influence of temperature, concentration of the excystment solution, oxygen tension, and x-ray irradiation on the excystment time.
