When Tao Shengwen heard Zhou Yu say that there was a solution, he stood up happily and hurriedly asked, "Mr. Zhou, is your thinking still flexible, may I ask what your solution is?"

Zhou Yu didn't speak, and pointed to the apple on Tao Shengwen's desk.

Tao Shengwen glanced at the apple on the desk, he shook his head and said, "This method doesn't work, we also experimented with fruit transplantation of Ceres' life organelles."

Its protein structure has not changed, and it still produces toxic polypeptides in mammals.

In addition, fruits do not contain enough starch to provide sufficient energy for normal human activities.

Even with certain genetic modifications, their growth cycle is relatively long.

This leads to an insufficient production of fruits, which can only be positioned as fruits, and cannot replace the role of staple foods and vegetables. ”

Zhou Yu saw that Tao Shengwen still didn't think of the solution he was about to propose, and reminded again: "Director Tao, do you know all the apple trees in the world, what technology is it produced?"

"I really didn't pay attention to this, aren't apple trees grown from apple seeds?" Tao Shengwen guessed.

As a scientist who studies cells, he doesn't care about agricultural technology at all, how can he know about the production technology of apple trees.

"All the apple trees in the world, it's produced by grafting technology, and if you know about grafting technology, you can understand what I mean.

The grafting scheme is the only one I can think of that can play the role of Ceres organelles and avoid its risks. Zhou Yu directly pointed out the way he thought of it.

Tao Shengwen began to understand grafting technology, which is an agricultural technique applied to fruit trees.

Many of the world's best fruit varieties are produced through grafting technology.

Taking advantage of the peculiarities of the plant, it is possible to graft the branches of peaches onto the trunk of pears to produce a new variety of peaches.

The wider application of grafting technology is to ensure the survival rate of fruit seedlings.

The survival rate of the native fruit tree is very low, and the apple is a wild close relative, but its root system is very luxuriant, and it is easy to plant successfully.

But the fruit is only the size of a cherry and is very sour and difficult to swallow.

Agricultural technicians graft the trunk of high-yielding and delicious apples onto the roots of wild apples.

The apple tree produced in this way is very easy to survive and can produce large and delicious apples.

Tao Shengwen learned about the grafting technology, he pondered for a while, looked up and said: "The grafting technology can indeed solve the problem of fruit-based space plants.

We placed the Ceres Life Organelles at the roots, and the grafting technique prevented them from communicating with each other, and the fruit it produced did not have the Ceres Life Organelles at all.

The genetic material of various fruits is exactly the same as that of similar fruits on the earth, so we don't need to carry out special propaganda, and the public can fully accept it, and it is not a genetically modified plant at all.

Some herbaceous plants with hard branches, they can also be grafted in this way. For example, tomatoes, eggplants, peppers, corn, sorghum.

These are annual herbs that complete their life cycle when they bear fruit.

But they are too expensive and cumbersome to do. ”

"Director Tao, you are also stuck in a mindset now, how do you know that these plants will still be annuals.

Most herbaceous plants are annual, mainly due to the environment in which they live.

For example, bamboo is a special herbaceous plant, and there are many bamboos in nature that are more than 10 years old.

There are Ceres' life organelles that provide enough energy for these herbs, and it is common sense to speculate that they should have survived longer.

Even space plants can only be annuals, which can provide staple foods and vegetables in the universe.

Its cost is also much lower than the cost of transportation from Earth to a space base. Cost is not a limiting factor for grafting options. Zhou Yu said his point.

Tao Shengwen can't think of other methods now, and he also thinks that grafting has a certain feasibility, and there is no harm in trying.

"Then let's try it, and I'll let the scientists arrange the experiment."

Tao Shengwen regained his capable demeanor, he got up and walked out of the office, gathered the scientists and began the experiment.

Grafting is a very old technology, and this technology is now very mature.

Scientists use genetically modified high-metabolic plants for grafting experiments.

This plant has a short growth cycle, taking only a few days to grow from seedling to maturity.

However, their nutrients and taste are very poor, and they can only be used for experimental verification, and cannot be cultivated on a large scale.

Using corn and tomatoes as experimental materials, scientists began to study whether the grafting scheme could take advantage of the advantages of space plants and at the same time avoid the disadvantages of space plants.

Tao Shengwen led the scientists to start experiments, and the scientists began to be unfamiliar with the grafting technology of space plants, and the plants died soon after grafting.

They continue to sum up experience, adjust grafting technology, and find grafting methods that are in line with space plants.

Zhou Yu accepted Tao Shengwen's invitation to come to the cell laboratory to see new species of space plants.

Tao Shengwen saw Zhou Yu coming, and he said complimentingly: "Mr. Zhou is really discerning, and he pointed us out the right direction at that time, and now the space plant project is a great success."

"Tell me about space plants." Zhou Yu said happily when he heard that the space plant project was successful.

Tao Shengwen led Zhou Yu to the planting area of space plants.

What catches your eye is a huge corn forest, and these corns have a special appearance.

The corn stalks are bare, not a single leaf is present.

The stalk of corn is thicker than other corns, and this stalk is also divided into two distinct segments.

The bottom fifth of the corn stalk is brownish-red, and the top four-fifth of the corn stalk is a cyan corn stalk, which is the same color as a normal corn stalk on Earth.

Corn has huge corn cobs on it, which are almost three times the size of normal corn.

Tao Shengwen happily introduced: "These are the staple food corn of space plants, and the genetic material of corn is exactly the same as that of corn on earth, and the nutritional structure is exactly the same as that of corn on earth.

The reason why it grows so big is that the corn root can provide it with sufficient energy, so that the cells can grow bigger and have a longer metabolic cycle.

This phenomenon is the same as the reason why plants grow well in fertile areas and poor in poor land. ”

Zhou Yu and Tao Shengwen walked through the corn forest, and saw volleyball-sized tomatoes, purple long eggplants about the size of a person's small arm, and pepper seedlings about the same height as a person.

Tao Shengwen said excitedly: "Now that space plants have been very successful, they don't need sunlight to survive.

During the seedling period of space plants, we carry out the cultivation of space plants, and when they grow to a certain extent, they are grafted with space plants.

Now that we have developed an automatic grafting robot, the seedling yield of space plants is very sufficient.

Space plants only need to be watered with an aqueous solution of methane, and it can survive in the cosmic environment. ”

After Zhou Yu visited the space plants, he gave a thumbs up and exclaimed: "The space plant project is definitely an epoch-making project, you have opened a new era of space development, and it will definitely go down in history."
