Great City Famous Park is harmonious ② ｜ How many of these new varieties do you know?

The wild peony, which is constantly innovative, the hot -tolerant and high -temperature dwarf, and the damp -resistant rose ... In recent years, Guangzhou plant scientific research has continued to make breakthroughs, successively overcome bottleneck technology, and the innovation of germplasm resources has increased. At present, Guangzhou has been built into Guangzhou gardening plant science and technology resource garden, and the nation's first national wild peony variety resource library is collected. A variety of, in the experimental garden of the Guangzhou Forestry and Garden Science Research Institute, some plant varieties that have not been seen before, or have known each other, will make people dizzying. In the magical Wanliang Garden, rich in Guangzhou green and beautify resource species, let the species of Guangzhou green and beautify, so People are amazing that here are rich plant resources for major flower city construction projects such as "Guangzhou Garden".

Recently, the reporter entered the Guangzhou Forestry and Garden Science Research Institute to explore the "stars" varieties born in Guangzhou's plant scientific research in recent years.

Beautiful Dimensum Kapok Sight 1: Wild Peony Gender Resources The most nationwide

Entering the Guangzhou Forestry and Garden Science Research Institute, it is like entertainment in the plant world. The most eye -catching is the wild peony. As the first country in the country, the wild peony variety resource library is collected here to conservation and conservation of the most wild peony species in the country -76 species; One; 2 types of breeding and breeding technology -2 types.

Among the wild peony varieties, the new varieties cultivated in recent years "Tianjiao", "Wish", "Super Group", "Clouds" and "Tianjiao 2" have received widespread attention.

Arrogant

Tianjiao No. 2

Yuncai "'Tianjiao' is selected from the F1 generation of seedlings with wild peony and Mao Yan as the F1 generation of seedlings." , Another new variety "Super Group", the shape is more cute and unique. "It was screened from the descendants of Mao Yan and the wild peony in India. The flowers were large and the flower diameter reached 10 to 13 cm." Said Saiping.

In the wild peony flowers, the reporter also saw a variety of light purple. The special thing is that the stamens are like petals, rolling into a ball of spherical, forming the inner ring of the petals, which is unique and unique. "This is a variety of 'wish', which is selected from the F1 real seedlings of Mao Yan and fine -leaf wild peony." Dai Se Ping said that "wish" is an evergreen small shrub, 0.5 to 2.0 meters high, plant type Stretching, but the flowering period and fruiting period are slightly shorter, only June to August and July to October, respectively.

Wish, but to be better than the flower and fruit period, then you have to mention the new variety "super group". "The most special thing about the flower is that the flower and fruit period is almost across the year, and the flowering period is from the end of May to the middle and late June." Dai Seping said.

Highlights 2: Dwarf Morning "Guangzhou No. 1" gradually promoted

In high temperature and high humidity areas, it is not conducive to the growth of grass. Especially at high temperature in summer, the variety of flower varieties will reduce varieties due to temperature reasons. However, after 10 years, the Guangzhou Forestry and Garden Science Research Institute finally overcome the problems of Guangzhou's summer high -temperature high -flowering landscapes and cultivated the F1 generation seeds of the new products of the low -cow.

Professor Liu Guofeng of the "Guangzhou No. 1" dwarfing glory Guangzhou Forestry and Garden Science Research Institute has been committed to the research of dwarf -cow and the cultivation of new varieties for more than 20 years. He told reporters that the biggest feature of the "Guangzhou No. 1" in the dwarf is that the flowers are huge, with the maximum flower diameter of 10 cm, which is one -third larger than the average dwarf.

"And its flower margin has waves, like a skirt; the color of the color is also very special, the flowers pink to light pink gradient, with white halo; the flowers also have a light aroma, elegant color, is a rare characteristic of short glory, has a rare characteristics of the cow, has a rare characteristic of the cow, has a rare characteristic of the cow, has a rare characteristics of the cow, has a rare characteristics of the cow, has a rare characteristic of the cow, has a rare characteristics of the cow, has a rare characteristics of the cow, has a rare characteristics of the cow, has a rare characteristics of the dwarf, and has a rare trait among the cow. Very strong decorative. "Liu Guofeng said, the short -handed glory" Guangzhou No. 1 "is weak and slender compared to the average dwarf cow, and the new varieties are better. It has obvious advantages in rain resistance, especially suitable for grown in high temperature and humidity in Guangzhou.

"Guangzhou No. 1" is reported that the dwarf -cow is an important grass flower in the world's widely cultivated application and enjoys the reputation of the "king of flower bed plants". However, currently the dwarf -beef varieties cultivated in my country are basically abroad. These varieties have poor adaptability to the humid and humid weather in my country, especially South China, especially South China. Therefore, it is particularly important and urgent to cultivate new varieties of dwarf -beef with independent intellectual property rights and can more adapt to climate conditions in my country.

According to reports, in the next step, the dwarf glory "Guangzhou No. 1" will combine Guangzhou's park flower mirrors and road greening to create a new excellent variety demonstration site to gradually promote and apply.

Views 3: Select 16 kinds of rhododendron green bridges

The greening of the bridge has a certain difficulty in planting. The car's tail gas is severe, the dust is large, the summer is high, the winter is cold, the bridge load is limited, and the green space is limited. In response to these difficulties, the Guangzhou Forestry and Garden Science Research Institute began to plant climbing plants such as Rhododendron, Ma Yingdan, and Winyo vine in 2004 to carry out test screening of plant varieties. Among them, the rhododendrons are the best and the strongest among many plants in the trials, and they stand out.

"Brazil Purple" Rhododendron According to Ruan Lin, the dean of the Guangzhou Forestry and Garden Science Research Institute, in recent years, in order to continuously enrich the green landscape of the bridge, the Guangzhou Forestry and Garden Science Research Institute collected more than 200 cuckoo varieties. Selection, ecological adaptability, and development and application potential, preferably the variety suitable for bridge greening applications. At present, 16 varieties have been applied to bridge applications. "At present, the germinated resource garden of the cuckoo has been completed, and more than 300 campaign resources have been collected. It is one of the most comprehensive resource gardens that have collected the most quality resources and the most complete categories in China." She said. It is worth mentioning that not only the color and cultivation applications have achieved excellent results. In terms of genomics research, Guangzhou has completed the sequencing of the Bougainville as the Bougainant Plum transcription group, screening related genes for regulating the formation of triangular plum color, and carried out wild peony and bougainvillea plums. Plant regeneration and multi -body induction research laid a solid foundation for biotechnology breeding technology.

Ruan Lin showed reporters the latest varieties in recent years. Among them, "Brazil Purple" rhododendrons, the branches are lush, the branches are soft, they are scattered, resistant, strong, and growing all year round. It is suitable for outdoor growth. There are also "golden heart two -color" rhododendrons. The leaves and flowers are very special. The leaves have gold plaques, and the color of the color is rich.
