Abstract:
Xanthoceras sorbifolia Bunge seed was used as test materials,using ten different pregermination methods,including heating in water bath,different concentration of H2SO4,KNO3,PEG-6000 and other reagents were used to treat Xanthoceras sorbifolia Bunge seeds,the germination rate,vigor,germination potential and other germination parameters were investigated after induction budding,and different pregermination methods were compared and analyzed,to screen methods for rapid release of dormancy suitable for Xanthoceras sorbifolia Bunge.The results showed that,the germination rate of Xanthoceras sorbifolia Bunge seeds was increased in different degrees by being treated with 80 ℃ water bath heating,4% KNO3 solution,5% PEG-6000 solution,GA3 solution,2% KNO3 solution,10% PEG-6000 solution,seed pre-soaking with 4 ℃ distilled water and 50% H2SO4 solution.By contrast,the germination rate of Xanthoceras sorbifolia Bunge seeds was inhibited by high concentration H2SO4 solution.The germination rate of Xanthoceras sorbifolia Bunge seeds heated in 80 ℃ water bath for 10 minutes could be increased to 55.83%,which was 9.3 times of untreated.
