Abstract: Artificial pollination between Cycas sexseminifera (the male) and C. panzhihuaensis (the female) was carried out．The results showed that these two species of cycads can interspecific hybridization, but the pollination need pollinators.

摘要： 以石山苏铁Cycas sexseminifera为父本，攀枝花苏铁C. panzhihuaensis为母本开展人工授粉，成功获得杂交种子并繁育成苗。结果表明，石山苏铁与攀枝花苏铁可以进行种间杂交，但传粉过程需要传粉者。
