云南首批200株太空樱花种苗顺利移栽

Core Viewpoint - The successful transplantation of 200 high-quality Yunnan winter cherry seedlings, cultivated from seeds that returned from space, marks a significant advancement in space breeding technology in Yunnan province [1][3]. Group 1: Space Breeding Technology - Space breeding utilizes extreme conditions in space to innovate breeding methods, allowing for the creation of superior genetic resources in a relatively short time compared to traditional breeding techniques [3]. - The first batch of seeds, weighing 220 grams (1,800 seeds), was returned to Earth by the Shijian-19 satellite, which was launched on September 27, 2024, and successfully landed on October 11, 2024 [5]. Group 2: Seedling Characteristics and Care - The seedlings exhibit good drought resistance and robust growth, with an average height exceeding one meter after more than six months of careful cultivation [5]. - The project emphasizes the importance of ongoing ground selection, observation, and comparative experiments due to the inherent randomness and uncontrollability of space breeding [5]. Group 3: Future Prospects - The transplantation of the seedlings is viewed as a new starting point, with significant responsibilities ahead in terms of nurturing and variety selection [5]. - The development of space technology opens new pathways for breeding ornamental plants, particularly woody species like cherry blossoms [5].
