“XXXXXWWWWW”中国科学院庐山植XXXXXWWWWW物园内日本金松罕见结出果实

  近日XXXXXWWWWW,中国科学院庐山植物园里,生长XXXXXWWWWW在海拔1100米山地上的一株金松XXXXXWWWWW罕见结出果实。松果上长出三片营养针叶,形态大小非常可爱。

  金松是裸子植物金松科金松属的唯一种,原产日本,别名日本金松。日本金松是一种孑遗植物,化石发现在2亿3千年前就已经存在,现代几乎没有和它亲缘关系非常相近的植物。庐山植物园金松引种历史久远,早在1935年就引种了金松种子,现有两株近90岁姿态非常完美的金松,是中国保育该树种成功的典范。

  目前,金松已被引种到世界各地,但由于其种子来源困难,自我繁殖能力弱,且生长缓慢,所以金松一直是一种非常珍贵的观赏植物。(记者 华山 制作 胡晓山)
