Black rose is a new variety series of Rosa in Rosaceae that Pan Changzhi specializes in scientific research. On February 17, China Flower News reported that Zhejiang flower farmers challenged the world breeding problem "Black Rose" and appeared in Shaoxing. Farmers' Daily, Green Times, Science and Technology News, qianjiang evening news, Zhejiang and hundreds of newspapers all over the country reported this scientific research achievement, and CCTV, Qianjiang TV and Shaoxing TV broadcasted the video "Black Rose". For this, Pan. The gold industry welcomes enterprises and businesses with economic strength to join in cooperation.
The purpose of cultivating black roses is to cultivate real blue roses. After five years of professional research, the blue pigment of blue rose was found, and the blue pigment came from black. After two or three years of cultivation and cultivation, a truly living and world-recognized blue rose can be cultivated and passed on to the next generation. My institute can cultivate several new varieties of roses every year, and I hope people from all walks of life at home and abroad can cooperate in the development. Provide rose seedlings, tissue culture seedlings and grafted seedlings. If you want to buy new international varieties of seedlings (roses and black roses), you must make an appointment before picking up the goods.
The origin of black roses
Valentine's Day roses are mainly red, symbolizing passionate love and passion. Besides, there are white, yellow, orange and pink roses. But do you know that there is a mysterious black rose in the rose family, which is very popular among young people in recent years because of its unique personality.
Black rose is the rarest rose in the world, and black rose is an extremely rare variety. It is said that every plant is cultivated and recorded.
At first glance, it was unremarkable, but after careful tasting, I found that she was mysterious and beautiful. At present, there are two common black roses on the market. One is called "black magic", and the pattern is neat and beautiful. Thick petals are black with red and red with black, giving people a thick velvet feeling and a luxurious and mysterious feeling; The other is called "Black Beauty", with a slightly smaller pattern, but more exquisite and unique, with a thick black and red color and a velvet luster of black gold.
In fact, black flowers in nature are very rare, especially real black flowers do not exist. Mainly because black flowers can absorb all the light waves in the sun, the temperature rises rapidly in the sun, and the flower tissue is easily damaged. Therefore, we often see red, yellow, orange, white and other colors of flowers. This is because these flowers can reflect the red, orange and yellow light waves with more heat in the sun to prevent them from burning delicate flowers, which is a self-protection function of plants. Black flowers do not have this ability, so they are gradually eliminated in the long-term evolution process. So the black flowers we see are actually crimson or purple flowers close to black, that is, "red is black, purple is black" in daily life, so are black peonies, black tulip and black chrysanthemums, and so are black roses.
