Abstract
On the Microscopy of Starch Granules of Germinated Potatoes. Microscopic examinations of normally germinated as well as germinated and dried potato tubers and of the germs as such showed that the generalized assertion of D. Grebel, according to which a “melting” should be characteristical for the fermentative degradation (germination) of starch, cannot be confirmed. Indeed, the described melting phenomena occurred with single starch granules, the majority of the fermentatively deformed starch granules, however, showed the typical changes (channel formation) as they are to be seen with starch granules of cereals.With partially dried potato tubers and their germs the starch granules showed changes like those occurring with curcuma starch. Factors that are responsible for this symptom are being discussed.
