摘　　要：对双丰单粒一号种子发芽率低的原因及其影响因素进行了探讨．发现非正常种胚、种子成熟度、母根窖腐病及父、母本花期不一致等对其发芽率影响很大。同时指出采取选择单粒种最佳繁育区域、加强米种田栽培技术管理、搞好肥水运筹等方式，可以使单粒种发芽率有较大提高并可通过精加工使其发芽率达到生产要求。The paper studied the reason for low germination precentage of Shuangfeng beet monogerm I and Some factors influenced on it . The results showed the gerndnation peforntage was affected by the following factors informal enbryo,grede of maturity, mother root rot during storing silo and patetnalmaternal are not blooming same time. Author also pointed out that ①selecting optimum breeding monogerm variety regjons, ②strengthening field management on seed farm, ③regulating the privision of water and fertilizers,can greatly inerease the germination percontage of beet monogerm
