Abstract

Basic properties of Sinojackia xylocarpa seed were determined and experiments with acid erosion , chemical treatment and low temperature were carried out in order to search out dormancy and germination nature of the seed .The results showed that weight of the seed coat , which has a good water permeability , occupied 88 % to 94 % of the total seed .The germination rate could reach at 40.06 % after the seeds had been treated with sulphuric acid for two days , and with 500 mgL-1 GA3 , then stratified outdoor at low temperature for a winter , but the control seeds could not germinate .Seed dormancy of Sinojackia xylocarpa is due to not only the poor air permeability and the mechnical restraint of the seed coat but the process that its embryo needs a period of time for post ripening as well .So , it belongs to a type of comprehensive dormancy .
