Agriculture University teacher: a fake news
In order to prove the authenticity of this post, the reporter took the printout downloaded from the Internet, and came to Fujian Agriculture and Forestry University School of Horticulture for verification. Horticulture College, Department of Vegetable Science teacher He Bizhu a look at this post on the straight shake his head: "In theory, like watermelon, such as agricultural products, are by the Department of Vegetable Science is responsible for the research and cultivation, but our department has never cultivated this blue watermelon, not to mention that our department does not have what the DNA laboratory, I still heard of the first time such a thing. Besides, if a blue watermelon is really bred, the seeds of this watermelon will carry the gene that controls the blue color, and the blue watermelon can be used to breed the next generation from the seeds. In addition, the release of this news that the person said in the Agricultural University part-time teaching plane is not credible, because can be in the Agricultural University part-time personnel, are generally some experts, the average person is not possible to enter the Agricultural University for part-time teaching plane, is certainly a false news."
The reporter cultivated a blue watermelon on the University of Agriculture, interviewed the teacher of the Department of Fruit Tree and a few are doing experiments in the experimental field of the College of Crop Science students, said that the post is purely fake news, purely some people's mischief.
It turned out to be PhotoShop production, netizens pointed out the obvious
In the website has seen this "fake news" Fuzhou University computer science students Xiao Xu said, he knew at first glance blue watermelon picture is obviously PS. In the computer to make this picture, as long as the digital camera beforehand to take a cut watermelon picture, enter the computer, the use of PHOTO-SHOP keying, color to change the color of the watermelon, it's no longer simple. "Not to mention the blue, is made into five colors, is also a breeze."
And a netizen is more directly point out the blue watermelon broken. He said that because the original shot was a red-fleshed watermelon, it left a red reflection on the metal utensils in the kitchen. In the subsequent PS process, the maker only changed the red flesh of the watermelon to blue flesh and posted it. But he didn't realize that the red reflections of the stove on the left side of the image, as well as the metal kettle and metal spatula, revealed the forgery. A more critical breach is that the green skin of the large watermelon next to the white bowl has a light red reflection of the small piece of leftover watermelon below it, and there is no more of that smooth and natural color transition that should be present on the skin, which is obviously made.
Of course, one of the most glaring errors is that Fujian Agriculture and Forestry University was written as Fuzhou Agriculture and Forestry University by the producer and publisher.
Blue-fleshed transgenic watermelon can be bred, but has no market value
Professor Wang Wencheng, who used to engage in research on animal and plant genes at Minbei Vocational and Technical College, believes that although there is no official report on the introduction of blue-fleshed watermelon, from a scientific point of view, it is entirely possible to make the traditional red-fleshed watermelon transformed into blue-fleshed watermelon. In the breeding process, as long as the genes controlling blue, green and purple from other similar plants are transferred to red and yellow-fleshed watermelons, it is possible to obtain genetically modified blue-fleshed, green-fleshed and purple-fleshed watermelons that are different from the traditional red color after combined breeding. In fact, like the colorful peppers, color-changing carnations, and blue goblin roses that have been bred and marketed so far, they are all GM masterpieces.
But Ms. He Bizhu of the University of Agriculture believes that it is not feasible from a practical point of view, to cultivate the traditional red and yellow-fleshed watermelon into a blue-fleshed watermelon, one of the cost is large, and then there is no economic value, so cultivating this kind of blue-fleshed watermelon is not very meaningful.
Network food rumors
Need to be reasonable doubt
There are many rumors about food, such as mouth-to-mouth way to drink mineral water is not safe, food poisoning drink yogurt will be detoxified, candied fruit containing high levels of sulfur dioxide will cause asthma, pork neck meat will destroy the human immune system and so on. More powerful is about cola, for example: cola plus MSG or beer will produce stimulants, and even produce sedative sleeping agent FM2; cola + barbecue = bone cancer. These rumors are quite sensational, and they are very convincing.
Taiwan's "Department of Health" Food Hygiene Director Chen Shugong pointed out that the network rumors to brief, sensational as a feature, and food-related network rumors can be divided into two categories. One is to present experts and scholars tone, or make up a serious personal experience, and then add some plausible theoretical basis for the organization. As long as a little evidence, it is not difficult to find most of the fabricated. Another network food rumors, is aimed at specific brands, spreading similar to "a chain store selling drinks will drink people to death," and so on, not only out of goodwill, and even malicious slander. In fact, some rumors can be said to have a long history, and with the network to change the face of the comeback, such as Taiwan has been passed for more than 20 years, "sausage + Nutella = cancer", in the network to "bacon sandwiches + yogurt will cause cancer", the two to the same hypothesis Both are based on the same hypothesis, and there is no medical evidence to support it.
In Taiwan, in order to prevent people from being misled, the Department of Health has asked people to collect and organize food rumors on the Internet, and then publish them on the official website in the form of questions and answers, so that people can understand their doubts.
In the mainland, there are many online food rumors, and online fake news is even more frightening. If the publishers of fake news are doing it for fun, it's just a matter of entertainment. What's scary is that some people are using human curiosity to achieve the purpose of commercial speculation, or even maliciously vilifying people, and that's going too far.
The network provides technical support for the spread of rumors, and people's gullibility and difficult to monitor the spread of rumors objectively contribute to the dissemination of rumors, we call on the public to sound honesty and integrity, cultural upbringing and truth-seeking in all matters of the spirit of the rumors on the network should be to maintain a "reasonable doubt" to confirm that there is a real thing or to let the rumors stop! The wise person should not forward the rumors to others for dissemination. If you have difficulty in distinguishing between the real and the fake, you can provide the relevant information to the relevant departments, to the authoritative source for verification.
