A technique was developed to assess cell metabolic activity and to determine the influence of light and nutrients on gas reside synthesis and bouyancy regulation in order to understand factors which favour their dominance, and thus how to control them. / Thesis (Ph.D.)--University of Adelaide, Dept. of Botany, 1998?
