Several conclusions were obtained: 1) 0℃-3℃ is the best temperature range for storing pollen of Larix olgensis. 2) At the same temperature, humidity is the key factor influencing the pollen vitality. 3) Different clones shows different resistance to low temperature. Among the ten clones 2# clone shows the highest resistance.展开更多
