Effects of ionizing radiation on changes in the level of gibberellin-like substances during Scotch pine seeds germination

Leszek Michalski

Abstract


The level of gibberellin-like substances in pine seeds exposed to ionizing radiation was investigated using extraction, fractionation, acid hydrolysis, partitioning on chromatographic columns and biological tests. It was found that the level of free and bound gibberellin-like substances is dependent on the applied gamma radiation dose. It is assumed that ionizing radiation may re-lease bound gibberellins into free ones.
