摘要
苏铁(Cycas revoluta Thunb.)是一种名贵的观赏树种,由于雌雄异株,栽培分散,多数只开花不结籽。通过人工授粉,获得了较多的苏铁种籽,为苏铁的有性繁殖提供了新的途径。
Being a rare species of ornamental tree, Cycas revoluta Thunb. flowers butcan not form seed in the main because the tree is dioecism and always be planted in scatteredplaces. Nevertheless, quite many seeds of the tree have been gained through artificial pollination which provides a new way to sexual reproduction of Cycas revoluta Thunb.
