This comprehensive achievement, titled “Traditional Flower, New Variety Breeding, Cultivation Technology and Industrializationâ€, won the Beijing Science and Technology Progress Award, Liang Xi Forestry Science First Prize, and two China Flower Expo Science and Technology Gold Awards. It has reached the leading domestic level and some of its contents are internationally advanced.
According to reports, Beilin University has made breakthroughs in the breeding, cultivation and promotion of traditional flowers such as plum blossom, peony, ground coverlet and Primrose. Breeding more than 20 varieties of cold-resistant plum blossoms resistant to zero temperatures from 19°C to 35°C and promoting them in the "Three Norths" region; the world’s first registered plum variety in the world and the boutique park, which has displayed 244 plum blossoms. Varieties of good cold-resistant varieties are the unique characteristics of Mei Mei and plum blossom research bases.
Experts established a new classification system for peony and peony varieties, successfully introduced 11 wild peony original species, established a domestic peony germplasm resource nursery, and obtained nearly 1,000 offspring from distant hybridization; developed the autumn flower peony matching flowering period regulation The technology and peony winter flowerless soilless cultivation technology laid the foundation for the annual production of peony; 2 special peony cut flower varieties were selected, 8 excellent clones were obtained, and the first true secondary was selected in China. New flowering peony cultivars; achieved a breakthrough in the cross breeding of peony and peony in China; obtained a large number of hybrid seedlings; applied for 5 invention patents, applied for 4 new cultivars, published the monograph of “Chinese peony peonyâ€; 2 to 3 new varieties of primroses with independent intellectual property rights were established, a primrose seed production base was established, and 30 million primroses were propagated. There are 20 to 30 new varieties of chrysanthemum. After being promoted in Shandong, Henan and other places, it has created direct benefits of 140 million yuan.
In the transgenic flower breeding research section, researchers have also made new breakthroughs. The main achievements are the establishment of stable molecular breeding systems for important flowers such as ground chrysanthemum, grass gentian, Dendrobium, petunia and other important flowers. Six lines of transgenic chrysanthemums (PEAMT), seven lines of transgenic petunias, and BADH were obtained. 6 lines of Gentian grassland gentian, 11 lines of chrysanthemum transformed CHS gene with different flower color, 7 lines of Dendrobium AP1 gene, 1 line of CHS gene Dendrobium, 78 lines of AP1 gene chrysanthemum, high efficiency and stability There are 5 regenerated chrysanthemum species, 2 high-salt-resistance, 1 salt-sensitive, and 10 middle-salt resistant grassland gentian species.
In the research and promotion of modern cultivation techniques of flowers, researchers selected five high-yielding cut rose varieties and a large number of potted and bulbous flower varieties, established a corresponding high-quality, high-yield soilless cultivation technology system, and studied cut flowers and potted flowers. The physiological basis of high-yield cultivation; the development of renewable agricultural and forestry waste instead of peat as a potted flower substrate has important significance for the protection of peat resources and the ecological environment; a 44.4-hectare promotion and demonstration base has been built, industrialized production has been realized, and a variety of flowers have been produced. More than 10,000 pots (strains), direct output value in the past three years reached 120 million yuan.
MAGIK Lift Series are made of PDO (Polydioxanone), it is a thread with no cones, thus no damage to the tissue. This is the same thread used in Cardiac and other surgeries as sutures, and thus it is very safe.
