苏格兰Terrestrial生态研究所的科研人员新近发明了一种诱导松树早开花的新技术。其方法是,在幼松的幼枝上钻一个极小的洞,然后注射百分之几盎司植物激素——赤霉素,促使幼树产生雄性和雌性花。注射后的洞口应立即封住,以防感染。松树一般到25年生时才开花,经这种方法处理后,5年生幼松无性系即可开始结实。 Researchers at the Terrestrial Institute for Ecology in Scotland have recently invented a new technology that induces early flowering of pine trees. This is done by drilling a tiny hole in young shoots and then injecting a few ounces of the phytohormone, gibberellin, to induce young trees to produce male and female flowers. The hole after injection should be sealed immediately to prevent infection. Pines generally bloom until 25 years old, after this method of treatment, 5-year-old Young pine clones can begin to grow strong.
