Gibberellins GA 1 , GA 8 . GA 19 . GA 29 . GA 20 and GA 56 (2‐epi‐GA 8 ). were identified by combined gas chromatography‐mass spectrometry in root extracts of elongating Salix pentandra L. seedlings. The presence of GA 8 was also demonstrated for the first time in S. pentandra shoots. The levels of GA 1 , GA 8 , GA 19 , GA 20 in shoot tissue and in roots were estimated by selected ion monitoring. While the amounts of GA 8 and GA 19 were similar in both plant parts. the levels of the biologically active GA 1 and its immediate precursor GA 20 . were found to be much lower in roots than in shoots.
