The effect of different dormancy breaking treatements on germination of Albizia julibrissin seeds

Albizzia julibrisin Durazz. with common name Persian silk is an exotic, small deciduous tree growing up to 5–16 m that is native to tropical and subtropical Asia. Albizzia julibrisin Durazz. seeds are dormant because of their hard seed coat and they need pre treatment in order to germinate. This study was carried out with an aim of overcoming seeds dormancy. The seeds were treated with sulphuric acid, nitrate acid, two different concentrations of gibberellin acid, hot water, cold water as well as freezing and scarification treatment. The control group was immersed into plain water, at room temperature. The aim was to determine the best dormancy breaking treatment that resulted with successful and fast emergence. Statistical results showed significant difference among treatments for breaking of dormancy of Albizzia julibrisin Durazz. seeds.
