4 种 endangered plant seeds, take last night, “Temple” to space “tourist”, and they are Putuo Carpinus, rhododendron tree, dove tree and the tree of heaven, of which two plants in Yunnan unique.
seed can not just go to space, “play”, so travel is a status symbol. Look at their backing: the national level to protect endangered species, endemic and rare plants Putuo Carpinus; only distributed in Yunnan, local elevation of 2100-2400 meters evergreen broad-leaved rhododendron forest tree; 10 million years ago, leaving the new generation of Tertiary dove under the relict plant; only in Yunnan, China was the growth of specialty Parashorea rare species.
select them based on
Recently, the reporter to the CAS Kunming Plant Research Park botanist ask the cuckoo’s habit of trees. Rhododendron tree is a type of primitive and ancient plants. 1919, human Tengchong County in Yunnan Gaoligongshan original tree was first found in the rhododendron forest, found in 2100-2400 m above sea level. At that time the age has been growing on trees more than 280 years old rhododendrons, tree up to 25 meters. Scientists hope that by the microgravity environment of space, the fine traits of trees cuckoo variation.
Parashorea do not have all day “heaven”, this time to “heaven” of the. This plant only found in mussels and recruit the complement of Xishuangbanna in the new camp to King floating around the 20 square kilometer area. In 1975, the Yunnan Forestry expedition found it.
Putuo Carpinus is a rare plant endemic to China, is the only one, is the national level to protect endangered species. Involucrata, 10 million years ago, the new generation of Tertiary relict plant left in the fourth glacial period, have been extinct in most parts of the dove, and only survived in some parts of southern China.
of course, space tourism could go to four kinds of endangered plant seeds, should be grateful to several high school students in Shanghai Minhang three. Because they are submitted, “carrying seeds of endangered plants program,” get adopted. “This program does not require any special wisdom, to see would be willing to adopt.” Microblogging was done for this review.
seed God’s role
why they go to space tourism? This “space breeding” relevant. Reporters learned that the use of recoverable spacecraft by cosmic radiation, microgravity and weak geomagnetic field and other factors on the plant, microbial mutagenesis, the seeds to generate variation, researchers need to be selected from mutant strain.
“Frankly, this is nothing new.” Yunnan technology told a reporter, so that the seeds into space, the early years it carried out.
from the “one God” to the “seven gods”, crop seeds have been equipped with objects in the list, the “Temple” and “eight gods” spacecraft are no exception. Compared with conventional breeding, the biggest advantage is the space variation of breeding high-risk, short breeding cycle, in a relatively short period of time, creating a large number of high-quality seed resources.
“seeds in space to accept cosmic rays, microgravity, high vacuum, the weak geomagnetic field and other factors, making the seeds to get the gene mutation.” Yunnan Science and Technology Department staff, said Wang Yan.
“Space breeding is the use of modern space technology to stimulate the plant cells by cosmic rays produce mutations, the genetic changes in plant traits inherent to good production traits bred new varieties.” Provincial Science and Technology Agency experts.
have traveled in space seed
reporter learned that, in 1999, carrying the Shenzhou No. 3 Seed in Yunnan into space to fill gaps in Yunnan space seeds. Yunnan, “Simao pine”, “Birch Tree Seed” has entered the space. In September 2006, 20 seeds of Marx and Mao 10 Kexi Nan Hua pine seeds and successfully take the “practice 8″ seed satellite.
China’s first breeding satellite, “Practice 8″, as the return type of science and technology experimental satellite, on September 9, 2006, at the Jiuquan Satellite Launch Center Long March II C carrier rocket from the launch , 236 in the circle around the earth on a spaceship travel 9,000,000 km, in orbit 15 days after completion of space travel back to the ground of lettuce, eggplant, snow peas, peppers, 15 varieties of a total of 3,000 seeds.
