Reproduction during spaceflight by plants in the family BrassicaceaeResearchers report on studies of reproduction in Arabidopsis thaliana in space during during the Chromex-03 on STS-54, Chromex-04 on STS-51, and Chromex-05 on STS-68 missions. The obstacles to seed formation were related to carbon dioxide levels. Other experiments examined in flight pollination and seed production in Brassica rapa during parabolic flight, a 4-1/2 month stay on Mir, and on STS-87. During the Mir experiment, Brassica seeds were harvested from seeds sown in flight. The second generation seeds grew to produce new seeds that contained more starch and less protein and lipid when compared to ground control seeds.
