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 CC

机译：Pydanon 对谷物赤霉酸含量的影响.研究了吡达农（哒嗪基乙酸的衍生物）在不同剂量和不同施用时间下对生长谷类植物赤霉酸含量的影响。尽管高浓度的pydanon导致植物茎长的减少，但其赤霉酸含量没有改变。另一方面，赤霉酸的合成被CCC还原，就像在早期的实验中一样。实验得出的结论是，pydanon 对谷类植物茎的生长迟缓是由 CC 缩短以外的其他机制引起的
