Succeeded in germination and growth of plants for the first time with 'soil brought back from the moon'
It was announced that an experiment was conducted to grow plants using the soil of the moon brought back by the Apollo program to see if the plants could grow using local resources in an extraterrestrial environment, and that they succeeded in germination and growth. .. However, it shows a severe form of stress and it is difficult to grow.

When humans live outside the earth in the future, whether plants can be grown on local resources is a big issue.Vegetables are already being cultivated at the International Space Station, and the germination and growth of plants brought from the earth to the surface of the moon have been confirmed, but 'whether plants grow on the soil of the moon' has not been verified.

Professor Anna Lisa Paul and colleagues at the University of Florida have found that the mineralogically the same composition as the sample of the lunar surface (regolith) brought back by Apollo 11, Apollo 12, and Apollo 17 is a simulated substance JSC. We challenged the growth of white-lipped nazuna using 4 types of -1A.

As a result, it was confirmed that Arabidopsis germinated in all regoliths. However, their growth was quite different, and Arabidopsis planted in the three lunar regoliths did not grow as well as Arabidopsis planted in JSC-1A. In particular, it can be seen that Arabidopsis thaliana using the Apollo 11 sample is in much worse condition than those of Apollo 12 and Apollo 17.
The image below shows the growth of Arabidopsis thaliana, which were grown in rows from the left end using samples of JSC-1A, Apollo 11, Apollo 12, and Apollo 17.
Arabidopsis thaliana raised on lunar regoliths grew differently, but all showed strong stress.
Professor Paul and colleagues describe the lunar regolith as 'it may be useful for plant production, but things are not very good.' In the future, he concludes that it is necessary to further elucidate the interaction between plants and regolith so that the lunar regolith can be used efficiently.
