摘　　要：以花粉萌发率为指标,利用离体萌发法研究了4种贮藏温度对6个百合品种花粉生活力的影响。结果表明:‘Justina Zantrijus’、‘Sheila’、‘Elite’和‘岷江百合’花粉最适合于4℃干燥冷藏,在最适贮藏条件下萌发能力最长可分别保持84、352、88、4 d;‘Brunello’花粉最适合4℃冷藏,萌发能力可保持70 d;而‘兰州百合’花粉最适合-18℃冷冻贮藏,萌发能力可保持49 d。花粉萌发率随贮藏时间的延长呈下降趋势,但在贮藏的某些阶段有明显上升的现象。The study was conducted to estimate the pollen viability of six genotypes and optimum storage conditions. Pol- len grains were stored in four storage temperatures and their viability was assessed by in vitro germination. The results showed that pollen of ＇ Justina Zantrijus ＇, ＇ Sheila ＇,＇ Elite＇ and ＇ Lilium regale ＇ storaged inside of desiccator at 4℃ was the suitable condition, which ability of germination could keep 84,35,28 and 84 days separately; pollen of ＇Brunello＇ stored outside of desiccator at 4℃ was the best way, which ability of germination could keep 70 days;however, the best storage condition of Lilium davidii var. unieolor pollen was stored outside of desiccator at -18℃, which vitality could keep 49 days. With the storage time increasing, the germination rate of lily pollen gradually decreased, but there were distinctly rising in some periods of storage process.
