Effects of experimental hypogravity on peroxidase and cell wall constituents in the dwarf marigoldDwarf marigolds grown from seed under experimental hypogravity are modified in lignin content, hemicellulose composition and peroxidase activity. The two conditions used, clinostats and flotation, induced changes differing in magnitude but qualitatively similar. Most responses on clinostats required correction for vertical axis rotational effects, thus limiting the value of these instruments in free-fall simulation. These findings extend earlier observations suggesting that increased peroxidase and decreased lignin are characteristic of growth under experimental hypogravity.
