Abstract
Large plasmodia of P. polycephalum were formed from mixtures of microplasmodia grown in shaker cultures exposed to 2.0 G [gauss], 75 Hz magnetic fields and nonexposed, control cultures. The exposed cultures had been grown continuously in the field and displayed a longer mitotic cycle than the controls. Mixed cultures displayed synchronous mitosis and a cycle length intermediate to the cycle lengths of exposed and control cultures. The cycle length of mixed cultures varied with the proportions of the mixture in a nonlinear manner. The results are discussed in terms of several models.
