遨游太空樱花种子在云南华宁播种

Core Viewpoint - The successful planting of Yunnan winter cherry seeds, which were sent to space and returned, marks a significant step in space breeding technology in China [1][3]. Group 1: Space Breeding Technology - The Yunnan winter cherry seeds, weighing 220 grams (1,800 seeds), were launched aboard the Shijian-19 satellite and successfully returned to Earth [1]. - The seeds are expected to germinate within approximately half a month after planting, reaching a height of about 1 meter for transplanting [3]. - The project aims to innovate cherry germplasm resources and enhance the domestic cherry industry in China [4]. Group 2: Research and Development - The focus will be on closely collaborating with project partners to monitor the growth process and conduct rigorous scientific tests to select superior varieties based on traits such as flower color, shape, and resistance [3][4]. - Advanced research methods, including morphology, cytology, physiological and biochemical testing, and molecular biology, will be employed to study the mutated plants [4]. - The initiative is expected to provide scientific evidence for large-scale grafting and propagation, promoting the cultivation of new varieties [4].
