1- GROWTH CHAMBERS, MEANS FOR ANALYSING PLANT GROWTH AND DEVELOPEMENT – THE DESIGN AND USE OF GROWTH CHAMBERS FOR INVESTIGATING THE EFFECTS OF ENVIRONMENTAL FACTORS ON PLANT GROWTH

Inchoosing or designing a growth chamber, an experimenter decides what environmental factors are to be controlled, over what range, and with what accuracy.
The biological and financial implications of certain of these decisions are discussed.
Particular attention is given to show omena arising from the use of artificial light, lack of control of humidity lack of control of carbon dioxide concentration, step changes in environmental factors and low frequency control action.

Attention is drawn to the difficulties of obtaining adequate replication of environments in space or in time and hence the difficulties of making a statistical analysis of cabinet data.
