Seed dormancy is an ecological adaptation for many plant species to avoid the stress and unfavorable environment of germination. However, there have been very few molecular or biochemical studies about the detail of seed dormancy. Prunus campanulata Maxim. (Taiwan Cherry) seeds are deeply dormant. Warm followed by cold stratification, which contains imbibition and warm following cold treatment, can release seeds from dormancy to germination. P. campanulata seeds become mature during warm stratification but will not germinate even in optimal condition. Dramatic changes of the sulfatase activities were observed following warm and cold stratification of the P. campanulata seeds. Desulfation might be important for the regulation of cherry seeds from dormancy to germination. This report explored desulfation and its effects on dormancy and development of P. campanulata seeds.
