Germination Characters of the Seeds of the Amygdalus pedunculata Pall.

By taking the seeds of Amygdalus pedunculata Pall.from different provenance as experiment materials,the water absorption regulation,germination characters and germination rates under different treatments were studied.Results showed that the seeds didn't have physiological dormancy;the influence of the illumination was not prominent;20～25℃ was the optimal temperature for germination;GA_3 didn't have remarkable influence on germination rate,but could accelerate the speed of germination;the wooden capsule was the main factor of hindering the seeds from germination;Germination tendency and germination rate could be greatly improved by breaking the capsule with the mechanical method;soaking the seeds for 4 hours with concentrated sulfuric acid could increase germination rate by as high as 40%.
