Zusammenfassung:【Objective】 The optimal dehydration and low temperature storage conditions are still the difficulties in the research of recalcitrant seeds. In this study, the seed vigor under different dehydration methods and low temperature storage conditions was investigated, in order to provide theoretical basis and technical support for the collection and preservation of recalcitrant seeds in subtropical areas. 【Method】 In this study, Castanopsis sclerophylla seeds were used as the experimental materials, and the germination ability of seeds before and after dehydration and cold storage was compared. The seeds were subjected to the different storage temperature (room temperature 20 ℃ and low temperature 4 ℃), and the treatment time(7, 14, 30, 60, 90 d), as well as different dehydration rate(fast and slow) and dehydration time(1, 2, 4, 8, 12, 24, 48, 96 h). The germination rate and germination index of the seeds under the interaction between low temperature and dehydration were analyze, to explore the effect of the inter
