title: The role of the gas phase in the greening and growth of illuminated cell suspension cultures of spinach (Spinacia oleracea, L.).
abstract: The gas phase developed above spinach suspension cultures critically affected their growth and greening. Ethylene accumulation inhibited greening; this effect of ethylene was antagonised when the culture gas phase was enriched with carbon dioxide.  Greening was enhanced by reducing the partial pressure of oxygen below the air level; this effect was observed when oxygen supply did not restrict growth.
