Effect of white light irradiation on the endogenous growth regulators content in seeds and seedlings of pine (Pinus silvestris L.)

J. Kopcewicz

Abstract


The increase of gibberellin content and decrease of amount of inhibitors in light irradiated pine seedlings were found. It was also stated that stimulating effect of light on pine seeds germination is correlated with the increase of gibberellin and simultaneous decrease of the inhibitor content. The inhibitor isolated from pine seeds proved to be a compound similar in some properties to abscisic acid.
