Inhibition of Pollen Respiration by Oligomycin

Abstract

EARLIER experiments showed that respiration of germinating pollen was characterized by an initial high rate prior to pollen tube initiation, a subsequent lower rate during which tube growth began, and a second high rate associated with extensive tube growth1. DNP (2,4-dinitrophenol) stimulated oxygen uptake during each of these three phases of respiration. It was postulated that respiration was dependent on oxidative phosphorylation and that the observed respiratory pattern reflected various rates of utilization and resynthesis of energy-rich phosphate compounds1.
