these data indicate ( i ) that between ph 6.2 and 7.8 internal spore ph has little effect on dormant spore properties , ( ii ) that there is a strong permeability barrier in dormant spores to movement of charged molecules and small uncharged molecules , and ( iii ) that extremely early in spore germination this permeability barrier is breached , allowing rapid release of internal monovalent cations ( h+ , na+ , and k+ ) .
