攀枝花苏铁(Cycas panzhihuaensis)是近年来我国苏铁属植物中新发现的一个新种。由于人工不断地采挖,资源破坏较重,再加上自然授粉结实率低,对这种植物的发展十分不利。为此,我们利用引种于公园内的攀枝花苏铁,进行了人工授粉试验。人工授粉的时间和方法当雌花出现20天左右,形成圆球形的球花,紧贴中轴韵大孢子叶顶端裂齿已松劲微微张开时,授粉效果最好。采集花粉宜选择无风晴天,在中午或下午进行,避免花粉受潮。并在雄花周围铺上纸片,轻轻摇动雄球花,使花粉飘落纸上。花粉随采 Cycas panzhihuaensis is a new species newly found in Cycas in China. As a result of artificial excavation, heavy damage to resources, coupled with low rates of natural pollination, the development of this plant is very unfavorable. To this end, we conducted artificial pollination experiments using the Panzhihua cycad introduced in the park. Artificial pollination time and method When the female flowers appear about 20 days to form a spherical ball flower, close to the axis of megasporium leaf tips have slightly loose open, pollination best. Collection of pollen should choose windless sunny day, at noon or afternoon, to avoid pollen damp. And spread the paper around the male flowers, gently shake the male flowers, the pollen on the paper. Pollen with mining
