Hearing Wu Hao's words, the others nodded and looked at Yang Fang. They also had questions in this regard.

And Yang Fang smiled and shook his head: "Actually, the impact is not big, we have not changed the original growth genes of the trees, so even if they grow in a constant environment, the trees will still sprout, grow up and then dry up. fallen leaves.

During this growth process, the leaves will still change color according to the color changing gene implanted. However, without the influence of these external factors, such as changes in temperature, humidity and light, the discoloration will be less obvious and less bright.

Because our basic mother tree is a plant that grows in a climate zone with four distinct seasons, it will grow in this constant environment. Without climate change, it will not grow well. This is the reason why some plants like sunshine, while others like shade, some are drought tolerant, and some like water. "

"Of course, in the future, we can implant new genes into it to change its biological characteristics. Or we can replace other basic mother tree species to adapt it to other climatic growth environments, thereby expanding it. The range of growth environment." Yang Fang explained to the crowd with a smile.

Is this kind of tree planting and maintenance complicated? Does it require special care? Obviously Zhang Jun was very interested in this discolored tree and asked his second question.

Hearing Zhang Jun's question, Yang Fang smiled and shook his head: "It doesn't need special care, just treat it as an ordinary ornamental tree and maintain it normally. Regular watering, regular fertilizing, regular pruning, and nothing else. .

Even if you don't care about it, it's also good, but it's not as beautiful as it is after careful care. "

How to cultivate this kind of tree, seeds? Wu Hao asked.

Yang Fang smiled and shook his head: "This is a transgenic plant, and there is still a lot of controversy about this type of plant. One of the very big disputes is that this transgenic plant can easily affect and contaminate other plant genes, thereby affecting the entire ecology. circle safety.

So based on this, this tree does not have any ability to reproduce, that is to say, it cannot reproduce through seeds and roots, and the only way to reproduce is to use high-pressure propagation **** for reproduction.

The discolored tree that everyone sees is actually produced by pressing the branches through high-pressure breeding balls.

The biggest advantage of this high-pressure propagation ball is that it can ensure the stability of the color-changing tree gene.

To put it bluntly, the principle of the high-pressure propagation ball is to tie a pressure ball on the branches of the tree, and some rooting drugs are placed in it, and the branches are continuously stimulated with pressure and drugs, so that it can grow roots.

Then, the rooted branch is cut off and replanted.

So to put it bluntly, no matter how many seedlings it breeds, it is essentially a tree with the same genes. Therefore, these bred saplings can not be regarded as the children of the mother tree, but can be regarded as brothers or even clones of the mother tree. "

The ornamental value of this color-changing tree is very high. When to get some planted in the Anxi Headquarters Park, it is also a display of technology and strength to the outside world. Wu Hao said with a smile.

No problem, we have already bred more than a dozen of these saplings. If you need them, we will breed some more, and then send them to the headquarters park in winter. This kind of tree grows very fast, basically it can grow very large in two or three years. Yang Fang responded very readily.

Hearing this, Wu Hao asked with a smile: "Fast-growing tree species, what is the lifespan of its growth like this?

I don't think there will be any problem for decades. If it is properly maintained, it is possible for hundreds of years. However, this is a judgment based on the data of the mother tree itself. It is unknown whether its lifespan will be affected after so many genes are implanted and gene editing is performed.

However, as an ornamental plant, it is already very good.

Of course, if we need to, we can also cultivate tree species with a life span of more than a hundred thousand years. However, this growth rate is too slow, and it basically takes decades and hundreds of years to grow into shape. It can be used for greening, but as a landscape plant, it is not suitable. "

Not necessarily a color-changing tree, other plant and flower varieties are also sent to our headquarters. There are many ornamental plants in our headquarters park, but they are basically popular varieties, which are too common. As a tech company, we have to show something special anyway, and these things are just right. This kind of low-key display and show-off can demonstrate our strength in this field. Zhang Jun looked at the discolored tree and said with a smile.

"Actually, if it's just a single color, it's pretty good, such as the gold color on the front, it's very beautiful."

When Wu Hao heard Zhang Jun's words, he couldn't help rolling his eyes. Sure enough, this product really got into the eyes of money, and this love is also full of money flavor. Golden tree, what does this guy think.

But what made Wu Hao different was Yang Fang's reaction. She smiled at Zhang Jun and said, "We also have the golden tree, please come here."

Having said that, Yang Fang brought Wu Hao and the others to a few golden trees, and smiled at everyone and introduced: "This is the golden tree we cultivated~lightnovelpub.net~ Its leaves are very bright in color, showing Bright yellow, and the surface will have a glossy feeling, like a piece of golden leaves.

Moreover, its fruit will grow into the kind of wind chime-like disc-shaped shell. It also has a golden color, like a sister's gold coin mounted on a tree, very beautiful.

Also, pay attention to its trunk, there will also be some golden dark lines all over it, which is very beautiful. "

This is my ideal tree. I want this tree, and I will bring it back to my house. I have to provide it well. Zhang Jun stared at the golden tree and said with a longing look.

hehehehe...

Hearing Zhang Jun's words, everyone at the scene laughed.

Wu Hao glanced helplessly at this disgraceful guy, then asked Yang Fang with a smile, "This is also the result of your genetic modification."

Yes, Yang Fang nodded and smiled: "Actually, there are many plants in nature that grow golden-colored leaves or flowers, fruits, etc. For example, the more common and familiar ginkgo, its color when it turns yellow It's very bright, like gold.

As for us, we extracted the color information on these plants and cultivated them accordingly, so that their leaves were golden yellow throughout the growth stage. Not only that, but its fruit, the disc-shaped shell, has also been edited by us to make it more like a coin. "
