摘　　要：采用TTC法对不同贮藏条件下的南京椴花粉生活力进行测定。结果表明:南京椴花粉的寿命相对较短,临界含水量为8.99%。在此含水量下,贮藏温度为-25℃时,经过8 d贮藏,花粉生活力从75%下降到56%,经过180 d贮藏,花粉生活力仅有25%。此外,新采集南京椴花粉的含水量为9.55%,可以不经干燥,直接在-18℃下保存。The pollen viability of Tilia miqueliana under different storage conditions was evaluated using TTC （2,3,5 - triphenyl tetrazolium chloride） testing. The results showed that the pollen longevity of T. miqueliana was relatively short, the critical moisture content was 8.99%. The pollen viability decreased from 75% to 56% stored at -25℃ after eight days, and was only 25% after 180d. In addition, the fresh pollen with 9.55% moisture content could be stored at - 18℃ directly without drying.
