The aim of this experiment was to explore effects of gibberellic acid on Chionanthus virginicus L. seed germination. The species has great horticultural values but due to problem in propagation it is rarely used. The seed possesses double dormancy: egzo and endo dormancy. Gibberellin has shown helpful in overcoming endo dormancy which is confirmed with this species. Different concentrations of GA3 had different influence. The lower one has shown stimulative effect while the higher one has shown the inhibitory effect. It is also confirmed that endocarp prevents germination.
