This "family relationship" is unique in the world!

Longan, sweet?

Litchi, delicious?

The "children" that they have mixed out of each other

Haven't eaten?

Our agricultural scientists

"New Living" again!

The first new variety of longan and litchi in the world

"Crispy" was born in our country!

Fresh and sweet, like longan

There are so many meat, like litchi

Is it a litchi or longan?

How difficult is this "family relationship"?

Fruit hybridization is not new

Such as orange

Is the descendants of grapefruit and oranges

But the story of longan and lychee

It's more special

Both longan and lychee belong to the familyless child

The two are relatives

From the appearance to the taste is very similar

So many people when they were young

Can't tell the two of them

There is also a "stabbing head" like a "stabbing head" red Maodan

Although they have their own personality

But just know it

They are indeed a "family"

But it's just a close relative

Longan and lychee cannot be combined together

This is because

There are strong reproductive isolation between them

Litchi and longan belong to the subordinate subordinates respectively

Different subordinates

Although the two are similar, they are originally neighbors

I have never appeared for thousands of years

Once there were foreign teams

Try to "match" longan and lychee

After all the descendants

As a result, "die" before growing up

Then there is no more

And this time, Chinese scientists have succeeded

Let Shi Yilong's eyes be a "mother"

Zi Niang Xili Litchi is "Dad"

Success and far -fate hybridization was born with new varieties "crispy"

This is the first in the world

New varieties of longan and lychee hybridization

Pioneering significance

How did you do it?

The "Wuzi" problem of longan and lychee

It was not until 2007 that there was a turnaround

Because, scientists have given them "medicine"

Not only "medicine"

Professor Liu Chengming of South China Agricultural University

Comprehensive use of the methods of physics, chemistry and biological

They disguised litchi pollen

I cheated the "defense" of longan

Realize pollination, successful fertilization

Scientists are before the flowering period

On the male flowers that are just open for longan and lychee

Gathering pollen

Then put the longan pollen

Eliminate with ultraviolet lights for more than 12 hours

Make it completely losing the germination ability

Then mix with the healthy lychee pollen

Send to longan stigma

The longan stigma at this time

Puzzled by a chemical "secret recipe"

I thought it was longan

Unexpectedly, it is actually litchi

"Deduades" longan

So successfully gave birth to "crispy"

"Crispy" is a longan or lychee?

This "crispy" that has just passed the new variety evaluation identification

After

It attracted a lot of curiosity

"Crispy" as the "child" of longan and lychee

Who is the appearance? Who does the taste follow?

Is there a seed version?

... ...

From the color point of view

Huang, with "Longan Mom"

From the perspective

Large, with patterns, like "lychee dad"

In terms of taste

"Crispy" sweetness can be above 21 degrees

With "mom"

Of course, the "crispy" of the advantages of "parents"

It also has its own unique advantage

That is frost resistance and late maturity

Litchi longan's fresh fruit period is short

Maybe

Mid -Autumn Festival, National Day and even October

You can eat fresh high -quality "crispy"

Finish this

When can we eat "crispy"?

Professor Liu Chengming of South China Agricultural University

Since 2007, he started to "talk" to Longan Litchi

After several years of experiments

Until this year

Finally passed the on -site appraisal procedure of the new variety, which means that "crispy" can be launched immediately

After three or five years, mass production will be achieved

Enter the market and put on the dining table

This "family relationship"

It's easy to say, it's hard to do

Behind "Crispy"

Have a lot of technical difficulties

Experts need to study day and night, constantly breakthrough

"Crispy" meaning

Not only is the new breakthrough on the "food" dining table

Even more

When everyone in the world says "impossible"

Chinese scientists stand out

And turn this "impossible" into reality

Sweat and time

Give the world a beautiful answer sheet

The world's first "crispy"

Do you expect?
