Grafted clones of Picea abies (L.) Karst. were used for the study. A very rapid and conspicuous rise in the content of gibberellin‐like substances chromatographically similar to gibberellin A 1 , and of indole‐3‐acetic acid, occurred during the brief period of most rapid shoot elongation. A few days later, when the shoot growth had terminated, very small amounts of both compounds could be detected. The changes in the qualitative pattern of gibberellin‐like substances were consistent with a suggested interconversion pathway leading from non‐polar to increasingly polar compounds
