UNITS FOR AUTOMATIC CULTURE IN ARTIFICIAL ATMOSPHERE - "C2 3A" PROJECT
A modular and convertible cultivation cell equipment has been designed which permits both bright lighting, with constant or variable wind and a sealed confinement. An electronic system pilots the gas analyses on seven different experiments and regulates four of the simultaneously.
The quantified measurements and input/output operations are recorded numerically for computer processing.
At present, the agronomy experiments being carried out are the marking with 14C of root excretions, the studying of the effect of oxygen on plant development and the production of corn grains uniformly marked with 14C.
The possibilities of growth analysis are illustrated from corn cultivations carried out up to maturity in an artificial atmosphere. The typical curves of hourly and daily CO2 consumption are given together with the evolution of the daily CO2 and water requirements during growth.
