Abscisic acid: Let Olympic flowers bloom

Beijing in July is a sea of ​​flowers. With the approaching of the Beijing Olympic Games, the construction of the Olympic flower construction project starting from the end of June is being stepped up. 15 million pots of flowers will be used to meet with the public in the new flower gardens, flower corridors and flower belts. During the Olympics, these flowers will welcome the arrival of friends from all over the world with the most splendid attitude. In the turbulent season, what made these fresh Chinese live in a dry climate in Beijing? The reporter found the answer at the Chengdu Institute of Biology, Chinese Academy of Sciences, which is the abscisic acid (S-Murine) developed by the institute.
The Beijing Olympics will be held in high temperature and dry in August, which is a very high requirement for drought-resistant and fresh-keeping of potted flowers. In order to ensure the quality of potted flowers in some important places, after a year of screening research, the Beijing Tianhui Garden Flower Research Institute decided to use the abscisic acid (S-Tauntin) developed by the Chengdu Institute of Biology, Chinese Academy of Sciences for the preservation of potted flowers. , Water-saving and drought-resistant cultivation. During the Olympic Games, there will also be 2.45 million pots of potted flowers with abscisic acid preparations placed on important sites such as the Airport Avenue, the main venue of the Bird's Nest, and Tiananmen Square.
It is understood that abscisic acid (pesticide trade name S- induced repressor) is an internationally recognized plant "resistance-inducing substance", can induce plants to produce drought resistance, cold resistance, disease resistance, salt tolerance, etc., can be adjusted Plant growth, improve the quality of agricultural products, reduce the amount of pesticides, widely used in the cultivation of vegetables, flowers, seedlings and food crops. A significant physiological effect of abscisic acid is the rapid closure of stomata. When the plants are exposed to drought, the amount of abscisic acid in the leaves increases greatly. For example, when the leaves of the bean are wilted, the abscisic acid content in the leaves can increase 1.5 times within 10 minutes. When the abscisic acid content increases, the stomata of the plant closes and the water transpiration decreases. After the plants were watered, the abscisic acid content decreased and the stomata opened again. Abscisic acid regulates the opening and closing reaction of stomata is rapid and reversible, so abscisic acid regulates the transpiration of plants.
Abscisic acid is a scientific and technological achievement of international leading level obtained by Chengdu Institute of Biology, Chinese Academy of Sciences. Under the support of the National Science and Technology Research Project, the “863” Program and the Knowledge Innovation Project of the Chinese Academy of Sciences, the Chengdu Institute of Biology of the Chinese Academy of Sciences has achieved major breakthroughs in the industrial production of natural abscisic acid and agricultural applications, and has obtained a series of research results. They screened out the high-yield strains of abscisic acid; deeply studied the production process of abscisic acid fermentation; established the first industrial production line for liquid absorptive production of abscisic acid in the world; researched and developed a series of abscisic acid application agents; for the first time in the world The agricultural application of abscisic acid was realized, which led to the development of global abscisic acid application technology.
The abscisic acid project group has also successively developed new products for the application of abscisic acid, such as “Fu Shi Zhuang”, “Bao Min Feng”, “Rejuvenating Rooting Agent”, and “Fu Sheng Zhuang Yong Ling”. These preparations improve drought resistance and cold resistance of plants. The comprehensive ability of disease resistance and other effects are significant, with an application area of ​​nearly 50 million mu. At present, Chengdu Institute of Biology is cooperating with the famous American biological pesticide company, and both parties will jointly develop the international market of abscisic acid.
