Abstract Any plants grown during long-term space missions will inevitably experience an extremely low magnetic field (i.e. a hypogeomagnetic field, HGMF). It is possible that the innate adaptation of plants to the earth’s magnetic field (i.e. the geomagnetic field, GMF) would be disrupted. Effects of the HGMF on plant physiological and metabolic processes are unclear. In this study we established a hypogeomagnetic incubation system on the ground and investigated the effects of the HGMF on the gravitropism and germination of soybean seeds. The gravitropism angle, germination percentage, germination speed, water absorbance ratio, seed weight, radicle length, radicle weight, and radicle weight ratio of soybean seeds grown in the local field and the HGMF were compared. In general, the gravitropism angle in the HGMF was smaller than that in the local field when seeds were positioned before emergence in such a way that the direction of the radicle was opposite to that of gravity. The germination percentage, germination speed, and radicle weight ratio increased in the HGMF compared to the control. Our results indicate that the germination and gravitropism of soybean seeds are affected by elimination of the geomagnetic field.
