Olive seeds from China's space station germinate on Earth

BEIJING -- Olive seeds that underwent space mutation experiments aboard the Shenzhou XIV crewed spaceship in 2022 recently germinated in the city of Longnan in Gansu province, Northwest China, according to the state broadcaster China Central Television.Researchers plan to transplant the olive seedlings from 315 grams of seeds outdoors in 2026 to help them gradually acclimatize to the natural environment.Space mutation experiments involve exposing plant seeds or tissues to extraterrestrial environment factors, such as microgravity, high radiation levels and extreme temperature variations, to induce genetic mutations.Through the experiments, researchers expect to develop high-quality olive germplasm with desirable traits, such as high yield, superior quality, early maturity and strong disease ...
