The degree of potato germination can be judged by observing the changes of potato surface. When potatoes begin to sprout, there will be tiny depressions and color changes on the surface. These depressions may appear as black spots or white spots, and the color change is caused by the outer layer of potato skin beginning to fall off. With the progress of germination, new buds will gradually emerge from the potato surface, and the state of germination will become more and more obvious. The time and degree of potato germination are influenced by many factors, including storage conditions, temperature, humidity and potato varieties. Humid and slightly warmer environments will make potatoes germinate more easily. When storing potatoes, keeping a dry and low temperature environment can delay the germination rate. Different varieties of potatoes may have different germination tendencies, some varieties are easier to germinate, while others are relatively difficult.
