摘　　要：利用离体萌发法研究了4种贮藏温度对峨眉山4种百合花粉生活力的影响。结果表明:4种百合花粉萌发能力干燥贮藏条件优于非干燥贮藏条件,耐贮藏时间随贮藏温度降低明显增长,花粉萌发能力随贮藏时间增长呈下降趋势,但在贮藏的某些阶段有上升现象。The study was conducted to estimate the pollen viability of four genotypes and storage condi- tions. Pollen grains were stored in four storage temperatures and their viability was assessed by in vitro germination. The results showed that the ability of four genotypes germination in dry conditions was better than in others, and the duration of storage was longer as the temperature decrease. With the storage time increasing, the germination rate of lily pollen gradually decreased, but had a distinct rise in some periods of storage process.
