International First! Rice seeds grown on the Chinese Space Station return home
12月4日
随神舟十四号飞船返回舱下行的
载人空间站第三批空间科学实验样品
Delivered the space application system at the landing site
And returned to Beijing early the next morning
Successfully arrived at the Chinese Academy of Sciences
Center for Space Application Engineering and Technology
What is inside the "space package" of "Shenzhou 14"?
Unbox with the camera
↓↓↓
"Cold-fresh package" delivered fast
Rice seeds harvested in space are back home!
According to reports, samples returned with "Shenzhou-14"
Includes 3 biological sample cold packs
and 1 containerless sample bag
Among them, inside the biological sample cold pack,
loaded with experimental samples of rice and Arabidopsis
underwent 120 days of space cultivation growth
Rice and Arabidopsis have completed
Seed germination, seedling growth,
the entire process of flowering and seed setting
This is also the first time internationally
the first completion of rice from seed to seed
Full Lifecycle Space Cultivation Experiment
Netizen:
China Space Station Expected to Achieve "Staple Food Freedom"
Hope to eat "Space Rice" soon!
Space Plants and Earth Plants
What is the difference between ?
By analyzing images obtained from the space
And comparing with the ground
Scientists have preliminarily seen
The effect of microgravity in on plants
↓↓↓
Preliminary experiments have found that
(1) The plant architecture of rice has become more loose in space; dwarf rice varieties have become shorter, while the height of tall rice varieties was not significantly affected.
(2) Rice flowering time in space is slightly earlier than on the ground , but the grain-filling period has been extended by more than 10 days, and most glumes cannot close. Flowering time and glume closure play an important role in ensuring sufficient reproductive growth of plants and obtaining high-yield, high-quality seeds. Researchers will use returned samples for further analysis.
(3) Ratoon rice experiments were conducted in space and ratoon rice seeds were obtained; two rice panicles can regenerate from 20 days after cutting the stalks. Researchers believe this provides new ideas and experimental evidence for efficient production of space crops. This technology can greatly increase rice yield per unit volume, and it is also the first attempt at ratoon rice technology in space internationally.
(4) In addition, Arabidopsis successfully bloomed in space. Researchers conducted the first study on key genes regulating photoperiodic flowering via the circadian clock in space . The follow-up research team will further utilize the returned materials to deeply analyze the molecular basis of Arabidopsis adaptation to the space environment.
Currently, returned rice and Arabidopsis samples
a portion has been fixed
rice seeds will be brought back to the laboratory for continued cultivation and freezing
"On a business trip" for over 590 days
Containerless Material Experiment Cabinet Achieves Full Results
The Containerless Material Experiment Cabinet is the first in China , and
the second in the world to successfully operate on orbit,
similar experimental facilities.
So far, it has achieved
Stable operation in orbit for over 590 days
Successfully completed on-orbit experiments with 7 boxes of material samples
Successfully heated 73 sample particles
Through long-term on-orbit experiments
The space application system has broken through and mastered
A series of key technologies
Obtained a large amount of important scientific data
Revealed a number of new phenomena in space experiments
And through ground analysis and research
Produced some preliminary results
Published multiple papers in international academic journals
Subsequently, scientists will continue to accelerate the development of
Research on deep undercooling solidification process of new metal alloys
and measurement of thermal physical property parameters
to obtain key conditions for high-performance ground preparation processes
Guiding the preparation of new ground materials
