The fruit of the potato and its seeds are the only unique organs of the potato for sexual reproduction. The seeds in the fruit are called seeds, the seedlings grown from the seeds are called seedlings, and the tubers are called potatoes. Because seed seeds can eliminate some viruses during sexual reproduction, seed potatoes sub-propagated with seed seeds can be virus-free under protective conditions.
In recent years, the use of seed seeds to produce seed potatoes has become an effective technical measure to prevent potato degradation.
If the potato is artificially crossed at the time of flowering, the seeds of the artificial cross can be obtained in the fruit, and then the new variety can be obtained after multiple selections. Smaller hybrid combinations can also be used directly for seed potato propagation and field production.
The fruit of the potato is a berry formed by the expansion of the ovary after flowering and pollination. The berries have round, oval and other shapes, the skin is green, brown or purple, and there are 100 250 seeds inside. After more than a month of fruit set, the peel turns from green to yellowish-white or white.
The fruit turns from hard to soft, and it is ripe. The seeds inside are small, weighing only 1,000 grams. The dormancy of the seeds is very long, usually more than six months.
The germination of solid seeds is slow, and the topping ability is weak. After emergence, the root system is weak, the leaves are few, and the growth is very slow before 3 or 4 leaves. Therefore, when planting with solid seeds, it is necessary to do a good job of germination and fine land preparation.
It can also be transplanted and planted in the field after the seedbed seedlings are raised, and the seedling management can be strengthened to obtain seed potatoes.

Potatoes are not seeds, nor fruits, but underground tubers.
In general, when sowing in production, the potatoes are cut into pieces according to the sprouts. Potatoes also bear seeds, and their aboveground parts also bear flowers and fruits, that is, their fruits and seeds, because the yield of propagation with seeds is low, so they are not used in production.
The relationship between growth and environmental conditions
Potato growth and development requires relatively cool climatic conditions, because it is native to the high mountains of the Andes in South America, with an average annual temperature of 5 degrees and 10 degrees, and a maximum average temperature of about 24 degrees. The mountainous areas of the southwest, northwest and some parts of the north of our country are close to the climatic conditions of the potato origin.
However, after many years of artificial selection, there are different varieties of early, middle and late maturing varieties, which can be planted in a variety of climatic conditions. But after all, potato plants and tubers have their natural properties in response to temperature, so it's important to be aware of these when growing potatoes.

1.Aerial part of the potatoThe entire plant of the potato is divided into an aboveground part and an underground part. Like most other plants, the aerial parts have stems, leaves, flowers, fruits, and seeds inside the fruit.
The stem of the potato is the vital organ of the potato, and it is the part of the potato tuber or seed that we grow that grows above the ground after germination. We call it the above-ground stem, and it has leaves and edges. When it grows to a certain period, it will bloom at the tip of the stem.
Potato flowers are self-pollinating and bear fruit when they fall. However, the seed setting rate is not particularly high, and many flowers do not bear fruit after falling, which is affected by a variety of reasons. The potato flowers are particularly beautiful, with pink and white flowers and yellow stamens.
One of the peculiarities of potato flowering is that the potatoes start to open around 8 a.m., close again around 5 p.m., and open again the next day. The flowering period of potatoes can last for about 5 days, and the inflorescence of each potato can last for about 15-20 days. When the flowers of the potatoes fall, they bear fruit.
The potato fruit is round or oval in shape, resembling the shape of a small tomato. Until it matures, it is green. When ripe, the top of the fruit turns white, and the whole fruit gradually turns yellow-green, brown, or purple-green.
This ripe fruit has a sweet taste, but never eat potato fruits, because the aerial parts of potatoes contain a toxic substance, solanine.
This substance is contained in fruits. Different potato varieties have different fruit sizes, ranging from 1 cm to 3 cm in diameter. Although potatoes can bear fruit, some fruits have no seeds, and a few fruits have seeds, and the number varies greatly, generally around 100-250, which may be affected by pollination.
2.The underground part of the potatoThe underground part of the potato includes the seed potatoes, roots, underground stems, stolons, and tubers (potatoes) that we often eat. Seed potatoes are left over when we sow the mother potatoes and rot in the middle and late stages of potato growth, so it is rare to see the remaining seed potatoes when harvesting potatoes.
The roots of the potato cultivated in the block are derived from the roots of the potato seed shoot, and there are no taproots and lateral roots, which are fibrous roots; Dividing planted potatoes into main and lateral roots is not the same as cultivating roots with tubers. Potatoes sprout and grow, and the part of the stem that is buried in the ground is called the underground stem. The length of the underground stem and the depth of tillage are directly related to the thickness of the soil in later tillage.
The axillary buds of the underground stems of potatoes grow underground, forming stolons, which grow almost horizontally underground. In addition, stolons can also branch, and fibrous roots can also grow on each node of the stolon. The length and number of stolons vary depending on the variety and cultivation conditions.
Nutrients begin to accumulate in this enlarged part, making the enlarged part larger and larger, which we call the potato, which evolved from the underground stolons of the potato, so it is called "tuber". We should know what the potatoes we eat regularly are. It is a tuber-shaped stem.
Tubers are the things we most want to harvest when we grow potatoes, which is the potatoes we eat.
-
Not belonging to the fruit, the potato it is the stem of the plant. The reason is that it has tooth eyes on it. There are buds in the eyes! It has the characteristics of a stem.
-
Potatoes are not fruits. Potatoes belong to the vegetable family. Because potatoes are grown in the land. Therefore, the land belongs to the vegetables, not to the fruits.
-
It does not belong to the fruit. Fruit refers to the fruit that bears after pollination, and potatoes are not like this at all, so they are not fruits at all.

Question 1: Is a potato a fruit or a pulp It is a tuber, formed by the expansion of the top of the underground stolon, which belongs to the vegetative organ.
Question 2: Is a potato a fruit Not a fruit, the fruit refers to the fruit that bears after pollination. The edible part of the potato is its root...
Question 3: Is it true that the potatoes we eat are the fruits of the potato plant? Potato, its botanical name is actually called potato.
"Potato" is the usual name. The tubers are edible, so when we say potatoes, we are actually referring to the tubers of potatoes (i.e. the part that grows in the soil).
Question 4: Does potato flowering affect fruit growth 15 points does not affect the yield, this period should be controlled, the potato bud flowering period is the key period for ingots, at this time, in case of drought, it should be watered in time, and then watered after this period, which will seriously reduce the yield and increase the proportion of deformed potatoes. The method is to pour water all over the bud, one is to increase moisture, the other is to cool down, the travel judgment is conducive to the formation and expansion of potato pieces, water twice every 10 days, and generally water three times.
The potato is neither a seed nor a fruit, it is the stem of a plant! It's just that its form and function have changed. The general stem stretches out into space to support leaves, flowers, fruits, and seeds, while taking on the heavy responsibility of transporting matter.
The potato nuggets are developed from the buds and come from the hopper, but it does not stretch to the space, but grows into the soil, and gradually becomes a fleshy and thick lumpy, which is the function of the potato nuggets to store nutrients and have the function of vegetative reproduction.
Question 6: What kind of dish are potatoes eaten? Roots, fruits, or stems? It's underground tubers.

Potatoes are stalks. Potato is an edible perennial herb of the Solanaceae family and is the fourth most important food crop in the world, after wheat, rice and maize. Potatoes are also known as "ground eggs", "potatoes", "potatoes", etc., the tubers of Solanaceae plants.
Along with wheat, rice, corn and sorghum, potatoes are known as the "world's top five crops".
Potatoes are native to the Andes Mountains of South America and can be cultivated in southern Peru from about 8000 to 5000 BC.
The main potato producers are China, Russia, India, Ukraine, the United States, etc. China is the world's largest producer of potatoes.
In 2015, China launched the "Potato Staple Food Strategy" to promote the processing of potatoes into staple foods such as steamed bread, noodles and rice noodles, and potatoes will become another staple food in addition to rice, wheat and corn.
