Abstract

Cress seeds (Lepidium Sativum) were exposed to a 2g hypergravitational environment in a centrifuge for eight days to test the effects of such gravity on their germination and growth. The purpose of this research is to simulate the gravitational conditions experienced on a super-Earth exoplanet. An identical set of cress seeds were grown without exposure to hypergravity for eight days as a control. After four separate runs, measurements showed a decrease in the growth rate of the test group compared to the control group. This decrease varied with each of the four test runs. However, all test groups showed a lower growth rate than the control group, between 5.25% and 15.63%. This experiment showed that exposing cress seeds to hypergravity for an extended period will cause these plants to grow shorter relative to control groups. Understanding what mechanism causes slower growth is essential for understanding how life might arise, grow and evolve on other planets with greater mass than Earth.
