Abstract
Negative photoblastism induced in white clover seeds at 5°C or by lowered water potential (−0.3 MPa, polyethylene glycol) was affected by ethrel, gibberellin A3, benzylaminopurine and kinetin treatments. The effects were different for water and temperature stressed seeds. The observed synergistic and additive effects of light and growth regulators confirm the earlier suggestion that there are two different mechanisms involved in the light inhibition of white clover seed germination induced by various adverse environmental conditions.
