Ethylene metabolism in Pisum sativum L.

Abstract
The possible role of C2H4 metabolism in mediating the responses of plants to C2H4 is re-examined. It is demonstrated that (i) the effects of inhibitors upon C2H4 action do not correspond with their effects on metabolism, (ii) elicitors of C2H4 effects do not have appropriate effects on C2H4 metabolism, (iii) inhibitors of C2H4 metabolism do not affect the response of plants to C2H4. It is concluded that metabolism of C2H4 is not linked to the mode of action of the growth regulator.
