As soon as growers learned to bud or graft, they chose as scion sources the trees that were superior for their area.
种植者一旦知道了枝接或芽接，他们就把当地的优良植株选来作接穗材料。
Analysis of variance showed extremely significant on survival and COINS growth between two grafting methods, which reveals that bud grafting excelled pith-cambium grafting on Korean pine graft.
经方差分析，两种方法嫁接成活率及成活后接穗平均生长量差异均极显著，说明红松采取劈接法嫁接优于髓心形成层贴接法。
