摘　　要：研究不同贮藏温度下花粉保存时间对番茄座果率和种子量的影响,以探究不同贮藏条件下番茄花粉的贮藏能力。结果表明:不同贮藏温度下,番茄座果率和单果籽粒数均随花粉贮藏时间的延长而显著下降,降低贮藏温度能有效延长花粉贮藏时间。研究以包头市农业科学研究所选育的CM966和CM196两个番茄品种为试材,采用常温20℃处理,有效贮藏期为11 d,低温5℃处理,有效贮藏期为15 d,冷藏-1℃处理,有效贮藏期为31 d,冷冻-18℃处理,有效贮藏期为31 d。相关分析表明,番茄花粉在5℃贮藏和-18℃贮藏2个处理中,平均座果率和平均单果籽粒数均和花粉贮藏时间呈极显著负相关,平均单果籽粒数和平均座果率间为极显著正相关。The effects of pollen retention time on tomato fruit yield and seed volume were studied under different storage temperatures to explore the storage capacity of tomato pollen under different storage conditions. The resuhs showed that the rate of tomato fruit and the number of single-fruit seeds decreased with the increase of pollen storage time, and the storage temperature was reduced eftectively. In Baotou city agricuhural science institute, CM966 and CM196 tomato varieties were bred as experimental materials.At the room temperature 20 -C , the effective storage period was 11 days, at the low temperature 5 ℃, the eftective storage period was 15 days, at cold storage -1℃, the effective storage period was 31 days, and frozen at -18℃, and the eftective storage period was 31 days. Correlation analysis showed that the tomato pollen stored at 5 ℃and - 18℃ had velT significant negative con＇elations for average fruit-set rate and average single fruit grain number. Con＇elation between grain number and average fruit-set rate was extremely significantly positive.
