Influence of low temperature on germination and endogenous growth regulator contents in Scots Pine (Pinus silvestris L.) seeds

Influence of low temperature on germination and endogenous growth regulator contents in Scots Pine (Pinus silvestris L.) seeds

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 t...
