摘　　要：[目的]针对高良姜产区没有种子标准,为了制定高良姜种子质量标准。[方法]测定不同贮藏时间的种子发芽率和幼苗整齐度,了解高良姜种子生物学特性,研究不同贮藏时间对高良姜种子发芽的影响。[结果]高良姜种子活性对含水量较为敏感,应属于顽拗型种子;随着贮藏时间越长,种子含水量越少,种子活力越弱,种子发芽率越低;在室内正常贮藏条件下,种子贮藏11 d发芽率90%,贮藏30 d发芽率80%,贮藏51 d发芽率73%,贮藏73 d发芽率仅65%,贮藏在111 d以上,种子丧失生活力。[结论]种子育苗应随采收随播种,提高发芽率。[Objective]In order to enact seed quality standard of Alpinia officinarum Hance,under lack of seed standard in production area of Alpinia officinarum Hance. [Method]The seed germination rate and seedling uniformit of different storage time were determined,the biological characteristics of seed of Alpinia officinarum Hance were understood,the impact of different storage time on seed germination of Alpinia officinarum Hance were studied. [Result]The seed activity of Alpinia officinarum Hance was recalcitrant seed,more sensitive to seed moisture content and as the storage time was longer,the less seed moisture content,seed vigor was weaker,the seed germination rate was low. In normal storage conditions of the indoor,the seed germination rate was 90% by storaging 11 days,30 days storage germination rate was 80%,51 day storage germination rate was 73%,73 day storage germination rate was only 65%,storage in more than 111 days,the seeds had lost viability. [Conclusion]The seed seedling should be sowed immediately after harvest,in order to improve germination rate.
