To find out, a trio of researchers at the University of Florida in Gainesville ran experiments with thale cress . This well-studied plant is in the same family as mustards and can grow in just a tiny clod of material. That was key because the researchers had only a little bit of the moon to go around.
Thale cress plants grown for 16 days in volcanic material from Earth looked starkly different compared with seedlings nourished in moon dirt . Plants potted in samples returned by the Apollo 11 mission fared worse than those planted in Apollo 12 samples or Apollo 17 samples .“Nothing really compared to when we first saw the seedlings as they were sprouting in the lunar regolith,” says Anna-Lisa Paul, a plant molecular biologist.
