Recently, the price of strawberries has dropped!
Family, strawberry freedom is about to happen!
CCTV financial reports: After the festival, strawberries, kiwis and other fruits generally reduced prices by more than 20 yuan!
Look at this big bright red strawberry, you can smell the fragrance across the screen.
However, on the road to realizing "strawberry freedom", there are always various "health parties" that set obstacles for us.
No, the recent video showing weirdly shaped strawberries is on fire again...
Such a big strawberry? Such a strange shape?
Bulking agents and ripening agents are certainly not less to fight!
Don't dare to eat, don't dare to eat.
Did you find it?
Every time they are confronted with strange food, the public rejects it for only one reason:
When I was a child, I didn't eat like this, and there must be something wrong with that!
We, are a professional CCTV agricultural account,
How can we not pay attention to this kind of big thing that concerns whether strawberries can be eaten with peace of mind and eat happily?
So we found experts in this area for consultation.
Li Baoju, researcher of the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences
Teacher Li said: Such strawberries are non-toxic and harmless, not only can be eaten, some are also sweeter.
In fact, such a strange strawberry is not an expanding agent at all.
And the heart-shaped strawberries on our market are healthy.
Long crooked, mainly because of this word: polyploidy.
All the strawberries we eat now are octoploid strawberries — that is, polyploid strawberries.
Polyploid plant fruits, some exist naturally, some are cultivated through breeding.
Strawberries are polyploid creatures themselves, and wild species in the genus Strawberry range from diploid to decile.
The so-called severalploids means that the organism has several sets of chromosomes.
One set of chromosomes is haploid, and two sets of chromosomes are diploid (we humans are diploid organisms).
I'm just the cute diploid creature
Eight sets of chromosomes are octoploids.
In fact, many of the crops we eat are polyploids.
For example, in cultivated potatoes, most of them are tetraploid, wheat is hexaploid, and seedless watermelons are triploid.
You see, multiploid creatures are everywhere around us, but we don't know the names of people.
Therefore, whether strawberries are polyploid or not, and whether they can be eaten or not, basically does not matter.
During the strawberry growth process, there are strawberries that look "normal" in these shapes.
There are also strawberries with "very different shapes" and "light bones".
Regardless of appearance, these strawberries have one thing in common: they can be eaten.
However, some people just hate the strawberries of "Ma Ma Lai Lai",
So, what is the reason why these strawberries look strange?
Experts say that strawberries look strange and have something to do with these small dots on the surface of strawberries.
These small dots are the seeds of the strawberry, and whether the seeds are successfully inseminated or develop determines the shape of the strawberry.
The main reason for these special shapes and deformities of strawberries is that when flowering, pollination and insemination are not normal.
If it can flower normally for pollination and insemination, it can expand and form a fruit.
Strawberries that do not have normal flowering pollination and insemination do not form fruit seeds, and they expand slowly.
In this way, from the appearance, its fruit is uneven and abnormal.
In order for strawberries not to be discriminated against and can be eaten decently, we growers can prevent the growth of "deformed strawberries".
First of all, choose good varieties - especially detoxified varieties.

In this way, the flowers will bloom particularly well during the planting process, and it is easy to form strawberries with beautiful fruits in the later stage.
Secondly, in the process of strawberry growth, polyploid strawberries due to abnormal pollination during flowering, cell division is too fast, resulting in conjoined, deformed, hollow and other phenomena of deformed strawberries.
In this case, it is necessary to control its temperature and humidity conditions,
As far as possible, take some methods of moisture removal to reduce the ambient humidity and make pollen pollinate in a normal environment.
In this way, the fruit we form in the later stage is more normal.
In fact, many of the things we eat are selected according to genetic cross-breeding.
In a word, multiploid strawberry defense: Although I am ugly, I am also very delicious. [Tears]
