Changes Induced in Peroxidase Activity under Simulated Hypo‐gravity

Abstract

A new method of inducing and maintaining a hypo‐gravity environment is described. Using this new technique (buoyancy compensation), the effect of reduced gravitational stress on dwarf marigolds (Tagetes patula) was studied. It was found that the specific activity of peroxidase was elevated significantly in gravity compensated seedlings. This effect, discovered with the buoyancy compensators, was confirmed with plants grown on traditional clinostats.
