摘　　要：[Objective] To study the long-term ultra-dry storage method and genetic stability of vegetable seeds.[Method] Seeds of Lycopersicum esculentum,Raphanus satuvus and Apium graveolen.were chosen as material.The changes of seed vigor,viability and genetic stability after ultra-storage were discussed by studying the seed potentiality,shoot length,germination percentage and the chromosome aberration rate of root tip cells.[Results] Maintaining the low moisture content,different vegetable species had different storage effects of the long-term storage seeds under normal temperature.The Lycopersicum esculentum and Raphanus satuvus seeds were more suitable to ultra-dry storage at normal temperature,and could keep good genetic stability,while the seeds of Apium graveolen had bad performance.[Conclusion] This study established the foundation of studying ultra-dry storage of vegetable seeds.[目的]对蔬菜种子多年超干贮存方法与其遗传稳定性进行研究。[方法]以萝卜、番茄和芹菜3种蔬菜种子为试验材料,从种子发芽势、苗长、发芽率和种子根尖细胞染色体畸变率等方面探讨蔬菜种子常温下长期超干贮存后活力、生活力及其遗传稳定性的变化。[结果]常温下长期贮存种子除应使种子保持较低的含水量外,不同的蔬菜种类会产生不同的存贮效果,萝卜、番茄等蔬菜种子较适宜于常温长期超干贮存,并能保持较好的遗传稳定性,而芹菜种子的贮存效果不佳。[结论]为进一步研究蔬菜种子的长期稳定保存奠定了基础。
