Twenty days-long stratification of Scots pine seeds results in the seeds germinating in similar high percentage in darkness as in light. The period of stratification enough to overcome the "barrier" of light is connected with simultaneous increase of gibberellin contents, especially with the appearance of the new groups of gibberellins qualitatively similar to those occurring in pine tissues under the influence of red and white light. It was also found that seedlings grown from stratificated pine seeds produce the increased amounts of gibberellins
