%X The rotational spectra of sporangiospores of Rhizopus arrhizus are investigated by the technique of electrorotation. Besides one co-field peak and one anti-field peak in higher frequency regions, another distinct co-field peaks were found for the living spores at frequency range around 500Hz. In addition, the differences in the spectra between the dormant sporangiospores and the germinating ones were exhibited by electrorotation. The Anti-field peaks of the spectra of the germinating were smaller in size than those of the dormant. Employed a modified two-shell model for ellipsoidal cells, the dielectric properties of the both spores were deduced from experimental data by mathematical simulation. As a result, the conductivities of protoplasm membrane and cytoplasm of the germinating sporangiospores are respectively increased obviously than those of the dormant ones.
