What do you know about potatoes?

Those who observed potatoes in the basement in early spring noticed that when warm weather sets in, long white whips grow from its tubers. These are young potato stalks, growing due to the lack of light in long shoots, which easily break off from the tubers. With such germination of potatoes decreases the amount of nutrients in its tubers. Eating sprouted in the dark potatoes is not harmful, but when sown, such germination will adversely affect the future harvest.

On a tuber the most healthy and powerful eyes sprout first; when they break off, the tuber loses the best shoots. The following germinating eyes will already be weaker, and they germinate with a delay. Save as planting shoots formed in the dark, it is very difficult. Meanwhile, it would be very useful to use already sprouted tubers for planting, since it accelerates the seedlings of potatoes and contributes to obtaining early harvest. It is only necessary that the potatoes germinate without the formation of long lashes. In the absence of light, shoots will grow and stretch, but this will not happen in the light.

Bring unsprouted potato tubers into the room, put them into the light, and they will begin to germinate quite differently. The eyes will begin to form tiny sockets of green leaves, sitting on the tuber. These sockets will increase in size, but without the formation of stems, so that the tubers can be transferred, transferred, planted in the soil without damaging these shoots. Sprouted potatoes in this way are good planting materials. For such sprouting potatoes do not require a large amount of light - it is enough to take the potatoes from a dark cellar into a bright room, scatter it in a thin layer or leave it in rare baskets.

Prolonged exposure to light causes a change in the composition and appearance of potato tubers: in the light, the tubers acquire a green color and some poisonous properties. It forms alkaloid solonin, especially poisonous in its raw form. Poisonous is only green peel, and when cleaning it, especially when cooking potatoes, it loses its toxic properties.

Potato germination begins as soon as the room where it is stored becomes slightly warmer than usual. For storing potatoes, the best temperature is 230; as it rises to 560, it begins to germinate. But in order for the tuber to begin to germinate, it must pass the rest stage. Therefore, freshly harvested potatoes do not germinate, even if it is warm.

Early potatoes, especially if they are planted with tubers previously grown in the light, can produce crops by the middle of summer. If the tubers from this crop were planted immediately after harvesting, then by the fall they would have managed to give a second crop. But in most cases they do not germinate or their shoots are very late. It depends on the passage of the so-called resting stage. If you keep these tubers on the glacier for 23 days, they will begin to germinate normally after planting and by the autumn will give a second crop of tubers. However, if you keep the potatoes in the cold longer, then it will become sweet, that is, it produces sugar. To do this, you need to keep the potatoes in the cold (about 1-20 frost) for about a week. This is explained by the fact that two different processes occur in parallel during storage in potato: one is that starch is converted into sugar with the help of the enzyme, and the other (tuber breathing) causes the destruction of sugar with the release of carbon dioxide. Both of these processes slow down with decreasing temperature, but to varying degrees. Breathing slows down rather than the formation of sugar.
