Abstract: 

Laburnum anagyroides Medik. is a popular ornamental tree native to the Mediterranean region. Its seeds are characterized of a physical dormancy, complicating seed reproduction. The present study was conducted to identify the seed dormancy breaking treatments to improve seed germination. The various stratification techniques (cold and warm treatments, alternate temperature regime) were tested. Simultaneously, the seeds were germinated in soil and on different nutrient media in vitro. The hot water treatment for 20 minutes and followed cultivating on the MS medium, supplemented with 0.5 mg/l BAP, was a most effective (77.7–83.8% of germinate seeds).
