研究了贮藏时间和温度对藜种子萌发的影响,结果表明：在-10℃条件下存放90 d后,藜种子发芽率下降了3.50%,发芽势上升了6.75%,与刚采集时的种子萌发无显著差异（P〉0.05）.室温和4℃条件下存放90 d后发芽率和发芽势显著降低（P〈0.01）.随贮存时间的延长,藜种子发芽率和发芽势呈下降趋势,发芽率和发芽势变化趋势是：-10℃〉常温和4℃;贮藏温度对藜胚根和胚芽生长无显著影响,贮存2年后则根长和芽长明显降低.

The effects of storage time and temperature on seed germination of Chenopodium album L. was studied in the present thesis. The result showed that seed germination rate of Chenopodium album L. dropped 3.50%, the germination potential rose 6.75 % when storage 90 days at - 10 ℃, but had no significant difference（P 〉0.05） compared to freshly harvested seeds. The germination rate and germination potential decreased （P 〈0.01） of storage temperature at room temperature and 4℃ after 90 days. With the extention of the storage time, the germination rate and germination of quinoa seed decreased, and the trends of germination rate and germination axe - 10℃ room temperature and 4℃. The storage temperature had no significant effect on the radicle and plumule growth of Chenopodium album L. However, the root length and bud length reduced significantly after storage for 2 years.
