ON THE INHIBITION OF FROST HARDENING OF WINTER WHEAT BY BASF 13-338, A DERIVATIVE OF PYRIDAZINONE

Abstract
BASF 13-338, a derivative of pyridazinone, inhibits photosynthesis without affecting. respiration in winter wheat (Triticum aestivum L.) at low temperature. This inhibition could account for the previously reported inhibition of frost hardening. Therefore, simultaneous inhibition of linolenic acid accumulation and of frost hardening are probably not causally related.
