Preparatory space experiments for development of a celss

Description	The goal of Closed Ecological Life Support System (CELSS) studies is to examine the effects of microgravity on yield and quality of plant products and on the interactions between irradiance and crop area. Measuring yield and quality of crops as a function of irradiance in microgravity is virtually unique to the CELSS program, as is the emphasis on canopies rather than individual plants. The first step for space experiments is to develop a relatively stress free environment for plant growth, something that has so far never been achieved. High light levels are essential, and there must be time enough to complete a significant portion of the life cycle. Optimal atmosphere and nutrients must be provided. Such responses as germination, orientation of roots and shoots, photosynthesis and respiration, floral initiation and development, and seed maturation and viability will be studied.
