  • Title: Growing super-dwarf wheat in Svet on Mir.

    Abstract:
    In cooperation with Russian colleagues, we will carry out three experiments with a super-dwarf cultivar of wheat in the plant growth chamber Svet on the Russian Space Station Mir: an early test of the root module and other instruments (July-August, 1995), a seed-to-seed experiment (1996), and a third planting that will be harvested after about 35 days, frozen, and returned to Earth for chemical analysis (1996). Plants will be photographed, sampled,and chemically fixed at intervals during the first two plantings. Instrumentation has been constructed to measure CO2, water vapor, air temperatures, infrared leaf temperatures, oxygen, pressure, irradiance levels, and moisture in the root module substrate (Balkanine). The primary objective of this equipment is to allow controllers to eliminate plant environmental stresses, leading to vigorous plant growth in microgravity. We are testing sampling and analysis techniques and growing plants in ground versions of Svet in Moscow and in Svet mockups in Utah: 12 chambers in two temperature-controlled rooms, with two compartments in each chamber (two temperatures, four CO2 concentrations, and three photoperiods in a current experiment).
