Abstract:

Abstract	It is generally accepted that higher plants will serve as important components
of environmental conditioning and food production systems for future space or planetary
surface habitats.  Because of structural considerations it is likely that atmospheric
composition and pressure will be radically different.  In defining growth systems
for altered atmospheres it is important to understand how plants operate in general
under altered pressure, growth conditions within the envelope must be optimized (dictated
by structural and operating parameters) and plant species and varieties most suitable
for use under the chosen conditions must be selected.  The traditional approach of
using a large scale field test is not cost-effective.  A means of simplifying and
reducing cost of research is needed to define the plant species and varieties and
the conditions under which these plants will be grown.  Using 11C02 extended square
wave kinetic analysis can non-destructively characterize the productivity and physiology
of plants under low pressure environments.  Specific methodology and apparatus necessary
for adaption of this technique is developed to evaluate plant function and productivity
under altered atmospheres and to develope a large scale evaluation program for species
and genotypes useful in space habitability systems.
