Influence of Pydanon on the content of gibberellic acid in cereals . The effect of pydanon (a derivative of pyridazinylacetic‐acid) on the gibberellic acid content of growing cereal plants was studied at variied doses and different times of application. Although high concentrations of pydanon caused a reduttion in stalk length of the plants, their gibberellic acid content was not changed. On the other side the synthesis of gibberellic acid was reduced by CCC like in earlier experiments. The experiments lead to the conclusion, that the growth retardation of the stalks of cereal plants by pydanon is caused by other mechanisms than in the case of shortening by CCC.
