In the brightly lit room, Tang Jiayi held a tablet computer in her left hand, her eyes swept over the petri dishes on the shelves one by one, carefully observing the small green life dots inside.

These are seedlings of some orchids, which are bred from seeds.

The fruit of the orchid is called the orchid, which contains tens of thousands of tiny seeds as small as dust, making it one of the smallest seeds in the world.

Because of the ancient literati's love for "plum orchid bamboo chrysanthemum", the orchid fruit orchid also has the meaning of excellent children, similar to the Zhilan jade tree.

However, the "elegant" literati and writers did not have the spirit and leisure of planting and cultivating orchids with mud in one hand and shovels in the other, they preferred to carry flower hoes directly into the mountains to "visit orchids", looking for wild orchids that are blooming or about to bloom, digging them down and putting them in flower baskets to take home. And under normal circumstances, manual work such as "visiting Lan" will also be done by others, and the "gentlemen" only need to appreciate the beautiful women in the valley who once "grew up in the deep mountains and no one knows" on the elegantly arranged small table, and now they are newly decorated and enjoy the luxury official kiln golden house, and it would be better if they could leave one or two Yonglan poems on paper and ink.

They will not care about the germination rate of orchid seeds and chrysanthemum seeds, the freezing of plum blossoms in the north is a symptom of the arrival of the Xiaoice River period, and the "down-stream learning" of bamboo flowers and bamboo rice will die.

However, thinking of the emperors in history who had many sons and grandchildren and created a nation by themselves, it seems that Lan Sun, who has a very low germination rate, is actually quite reasonable to compare excellent children.

Because it is rare and strange, the literati put the label of the phoenix on the bamboo food, and the phoenix is known as "not the sycamore does not live, and the bamboo does not eat".

The seeds of bamboo are rich in nutrition, and the ancient books record: "The seeds are thick, the color is red, and the taste is particularly fragrant." Bamboo rice, through the gods, light body and qi. "Modern nutritional analysis has also proved that bamboo rice contains a large number of starch, amino acids and trace elements, which has nutritional value and therapeutic effects, and is indeed a high-grade food.

In contrast, orchid seeds without endosperm structure are very pitiful. Because there are almost no nutrients in the seeds, the germination rate of orchid seeds is horribly low, usually 1 in 10,000. In the wild, orchid seeds rely on the help of orchid symbiotic fungi to survive the initial seedling stage by the nutrients obtained by orchid root bacteria to break down bark and grass clippings organic matter.

If the natural environment required for the germination of different varieties of orchid seeds is strictly simulated, and the disinfection, temperature, humidity, pH, and nutrient content ratio are carefully arranged, the orchid seeds can germinate in a relatively high proportion. However, this is too troublesome, usually the sowing and propagation method is only used for the breeding of new varieties, and most artificial orchids are produced using ram culture or tissue culture.

Although both tissue culture and seed propagation require the use of petri dishes and artificial media, tissue culture is much easier. After all, the former uses plant fragments that are much larger than seeds, contain a larger number of cells, and are much more adaptable to the environment.

Tissue culture technology uses the holographic properties of plant cells, and any living plant cell can continue to divide and develop under special conditions, and eventually form a complete mature plant. Unlike animal somatic cells, which can only divide and replicate themselves, and there is a limit to the number of divisions, plant somatic cells can be reversed into other types of cells under special circumstances, and there is no limit to the number of times. Therefore, factory seedlings usually choose tissue culture technology, which picks a small piece of live fragments from the live plant, cleans and disinfects them and puts them on top of a special culture medium, and finally new seedlings can be obtained, which can be used for field planting.

After endangered plants such as silver fir metasequoia, dove tree, alder and yew were declared endangered, some people sold their seedlings online, because with the help of tissue culture technology, people can easily produce seedlings of these endangered plants in large quantities. However, transplanting seedlings into the wild is not something that can be solved in a short time, so these species are still endangered in the wild.

Tissue culture technology is not only used for the conservation of endangered plants and the production of flowering and medicinal plants, but also for general agricultural seed production.

For example, because the United Nations General Assembly declared next year as the "International Year of the Potato", it was discovered that it usually only appeared in sour and hot shredded potatoes and French fries, and unknowingly became the fourth largest food crop in the world, second only to corn, wheat and rice, and potatoes that have contributed a lot to solving the problem of global famine.

Potatoes have a strong ability to multiply, and each small bud on the underground tuber can develop into a new plant after drilling out of the ground. However, this will cause some plant viruses that live on potato plants to pass on to new plants, affecting crop yield and quality.

Usually, the main potato detoxification technology is to collect uninfected plant tissues at the tip of potato buds, culture them, cultivate detoxified potatoes, and then use detoxified potato plants for secondary tissue culture to make more detoxified potato seedlings, and finally plant them in the field.

The reason why these orchid seedlings in front of Tang Jiayi did not choose a simpler tissue culture technique, but made it difficult to choose seed culture because their seeds were specially treated.

They are all common Phalaenopsis seedlings in the local area, but the growth conditions of the seedlings in the petri dish at the moment are very different, and they do not have the same batch of seedlings that should have a uniform feeling.

This is because they have been treated with special methods, and the effect is somewhat similar to space breeding and radioactive breeding, where the genetic material in the orchid seeds is randomly destroyed by external conditions, resulting in changes in the genetic information they carry, and finally there are many strange-shaped individuals among the thousands of germinated seedlings in hundreds of petri dishes in this room.

Seeing the bead-shaped, symmetrical, robust and beautiful seedlings, Tang Jiayi will write down the petri dish number on the tablet she holds in her left hand, and then collect them together for more detailed observation and recording, and then place them on a separate shelf for centralized management, enjoying the best and most careful scientific care.

And those who look strange and obviously crooked, her treatment is much more coarse, plus these little lives are already fragile, and every day some small seedlings are found by her to deteriorate or even die.

Tang Jiayi: The main thing they do here every day is to observe the growth of seedlings and clean up these dead seedlings in time. Of course, according to the growth of normal seedlings in other comparison groups, the indoor red and blue fill lights and temperature and humidity are carefully adjusted to maximize the growth and development of Phalaenopsis seedlings.

White light is formed by a mixture of light that contains at least three colors: red, blue, and green, with green light being ineffective for plants because the chloroplast, the main body of photosynthesis, reflects green light and absorbs only red or blue light.

Artificial lighting of plants, using white light directly is usually not very effective.

Light that appears bright to humans may not contain much of the light wave component that plants need. If the intensity of light in a specific wavelength range on the chloroplast of the plant is insufficient, resulting in insufficient photosynthesis intensity and not exceeding the photosynthesis equilibrium point, the oxygen produced by plant photosynthesis will not be as much as the oxygen consumed by the plant's own respiration, resulting in the plant not growing but becoming weaker and weaker.

Therefore, the plant factories that do not rely on natural sunlight and mainly use artificial light sources for lighting are actually filled with purple light most of the time, to be exact, purple-red, and the ratio of red to blue light is 2:1 or even 8:1, and the specific ratio needs to be adjusted according to the plant variety and growth stage. This provides sufficient intensity of red and blue light to drive plant photosynthesis.

As for the bright white lighting in the nursery now, it was the light that Tang Jiayi had just turned on, and it was specially for her to check the situation.

In fact, the use of bright enough high-pressure sodium lamp, trichromatic fluorescent lamp and other white light sources as lighting, in fact, can also be used for plants to supplement light, but the energy utilization efficiency is not high, far less than the current use of red and blue LED strip lighting to save electricity, and LED light source luminous efficiency is higher, less heat, not easy to affect indoor temperature control.

However, even if this seems to be a mature and usable factory production, it can only be used for the cultivation and production of shade-loving and shade-tolerant plants that are small in size, can be densely planted, and require low light intensity.

As for the problem of factory production of food crops, let's study the chlorella wall-breaking technology, or the duckweed wall-breaking technology......

……

Hearing the gurgling sound of the cart, Lu Xinquan turned his head to look at the door, and sure enough, Tang Jiayi was back. Seeing that there were twenty or thirty petri dishes containing seedlings on the stainless steel cart in her hand, Lu Xinquan couldn't help but shout: "Oh my God! Kill me! Yesterday's one hasn't been analyzed clearly, but today is here again!"

Although she deliberately lowered her voice, she still disturbed a few people sitting in other directions, all of them were girls, all of whom were Tang Jiayi's classmates in Class 61 of the Department of Biology.

"Okay, okay," Seeing that everyone was looking at her, Tang Jiayi's face turned straight and said: "Second sister, you are completely self-inflicted, who let you pick that difficult topic? You're just too ambitious!"

This is the backyard of the Tang Hua Plant Extract Flower Art Shop, this small flower shop is completely Tang Jiayi's property, except that most of the seeds used are provided by Atletico Madrid, and the projects they are currently carrying out have basically nothing to do with Atletico Madrid.

Intentionally or unintentionally, Tang Jiayi also gradually became more enterprising and competitive, this was originally just a small shop to meet the dream of a little girl's romantic flower shop proprietor, so she continued to increase her capital and expand, building a small glass greenhouse, a plant factory, and now this small plant laboratory in the backyard.

All of this is because of an electric shock socket that Atletico Madrid came up with.

As a computer science student, Atletico Madrid has made a lot of achievements in the field of software and hardware, and has many inventions under his name. But what makes Tang Jiayi embarrassed and depressed is that many of Atletico's inventions involve the field of biology, and most of them are realized without their own participation.

Whether it is the early electronic hypnosis pads, binocular cameras, later fantasy vases, sleep aid pillows, and now the heart keys and scheming that make him anxious, a lot of biotechnology and principles have been applied.

Of course, except for the very fantastic electronic hypnosis pad and fantasy vase, most of them just applied some simple biological principles, and they didn't put much pressure on her. But the electric shock socket that Atletico suddenly took out one day almost shattered her scientific outlook, world view, and outlook on life......

Atletico once performed a "magic trick" in front of her, making a budding rose bloom in his hand in an instant.

Tang Jiayi always thought that this was magic, and like other magic tricks, it was just a quick trick, until Atletico took out the rough-looking and ugly electric shock socket, and she realized that things were far more complicated than she imagined.

The shock socket is roughly a plastic box, about the same size as a tissue box, and the built-in rechargeable battery drives the LED light group and Bluetooth chip, and the lighting sequence and pattern of the LED light group can be switched through Bluetooth remote control. Tang Jiayi originally thought it was another electronic vase similar to a fantasy vase, but when she took out a budding lily cut flower from the bucket according to Atletico Madrid's prompt, and then cut off the two centimeters of the bubble underneath as required, and inserted it into the small hole directly above the electric shock socket, she was surprised to find that the lily seemed to "come to life", and it bloomed slowly at a speed visible to the naked eye in front of her eyes.

Although in various documentaries, she has also seen a lot of slow-motion photography and fast-blooming flower blooming animations, but that day she operated it herself, and then watched the flower slowly bloom (in fact, it is accelerated relatively normally) and release the fragrance, Tang Jiayi fell into a situation where her brain was short-circuited and unable to think in a short time.

Fortunately, although this thing looks fantastical, it is actually within the coverage of her worldview, and she has also watched Atletico Madrid's performance of the blossoming of her palms, and she has been prepared for a long time, so she did not really collapse with three views.

Usually, cut flowers do not die immediately, and if they are well kept, it will take several days or more for the plant cells to die. It is not impossible for cut flowers to open before the flowers wither and the branches become black and smelly, and cutting off the flower branches usually does not interrupt the flowering process, but it is naturally impossible for the flower bones to continue to grow and expand and the subsequent pollination and fertilization to produce seeds.

On the table in this laboratory there are now five shock sockets in the shape of a large and thin-necked vase, which is the second generation of the product.

In fact, this thing is divided according to its function, and it should be called an "electronic flowering vase", but whether it is Tang Jiayi or a few other girls who have seen the magical effect of this thing, they are happy to call it an electric shock socket.

Although even Atletico himself couldn't tell that this thing was not applied to biological electric shock technology, Tang Jiayi and the others agreed that the principle of this thing was to shock the poor cut flowers to cause them to bloom quickly and release their aroma, and then quickly wither. In fact, it was not only the cut flowers in the vase that were shocked, but also the scientific outlook of a few people that was not yet solid and stable.

Although there is also the idea of bringing this thing to the market and "shocking" more people's three views, Atletico and Tang Jiayi were depressed to find that the stability of its core circuit is not reliable, and it is even more uncontrollable than the original electronic hypnosis pad, and it is completely assembled and produced by Atletico Madrid's bare hands, and even then there is only a pass rate of less than 30%. The production is really limited, and in the end, this electric shock socket has become an exclusive gift for Atletico Tang Jiayi.

Through Bluetooth remote control, it can promote the rapid flowering of a variety of common cut flowers: lily, yueji, gladiolus, chrysanthemum, gerbera, etc., and can stimulate the parenchyma cells of the petals to release more aromatic substances into the air, so that the aroma of cut flowers is not as good as the status quo of potted plants.

However, although it has been figured out how to set up the stimulation program to correspond to different varieties of flowers, this is only the result of blind experimentation like traditional Chinese medicine, and there is little theoretical support. It is also because of this that the output of Atletico Madrid's electric shock circuit has never been able to rise, and each circuit must be tested repeatedly after it is done to confirm whether it is qualified.

However, the reality of this "manual circuit" also makes this product the best confidential product in Atletico's hands, and it is not afraid of being cracked and pirated at all, because even Atletico itself does not know the principle of this thing. In other products with clear principles, binocular cameras and sleep pillows, Atletico Madrid has suffered a lot of losses, although there are many related products on the market, but the vast majority of them are produced by other manufacturers.

Even because the bee brand is too new and the advertising is insufficient, many times it will be mistaken by consumers for copycat piracy. However, with the gradual activation of the Bee legal department, the popularity of the Bee brand is expanding, because the patents related to these products are held in the hands of Atletico Madrid.

Even if the infringement lawsuit is long and the compensation is only 100,000 yuan in the end, even if the lawsuit is won, it is a good way to expand its reputation at a low cost, although such a reputation will inevitably give people the impression of aggressive patent trolls.

Because the principle is not clear, the latest version of the electric shock socket only applied for a design patent in the name of an electronic dimmable vase, but did not apply for an invention patent.

At the beginning, Tang Jiayi and the others tried to give full play to their professional advantages, reveal the secrets of this thing, and "snatch" Atletico Madrid's patent, but the field of plant electricity is too cutting-edge, far from being solved by a few of their junior students who have just come into contact with professional botany, and in the end, it will not be solved.

Now their research project is also related to plant electricity, but it is not a direct study of the principle of this phenomenon, but the result of studying the phenomenon of plant electricity. The Phalaenopsis seeds that were the subject of the study were all treated with "electric shock" by Atletico Madrid, resulting in genetic mutations similar to space radiobreeding breeding, and what they had to do was to find new varieties with smaller plants and strong environmental resistance among these genetic mutants.

But it's basically a needle in a haystack.

Unless a specific gene is found, and then the genetic information of plant cells is genetically engineered and artificially customized, plant selection and breeding will be as purposeful as it is now. It can only be said that fortunately, it is not a carved boat seeking a sword with an uncertain goal.

Of course, with their current experimental skills, they can't do genetically modified experiments, so they can only find a needle in a haystack. For mobile phone users, please visit http://m.piaotian.net
