[Growth-inhibitory substances in barley grain during postharvest ripening].

The investigation studied the occurrence of growth-inhibitory substances in barley grain during postharvest ripening cultivated in different climatic zones. It was shown that the amount of inhibitory substances accumulated in grain was higher under unfavourable ripening conditions. Heat treatment of freshly harvested barley accelerated their disintegration. The disappearance of growth-inhibitory substances coincided with the termination of postharvest ripening of barley grain.
