adventitious bud：不定芽
(一)芽(bud)的类型按芽在枝上发生位置是否确定,芽分为定芽(normal bud)和不定芽(adventitious bud)两类. 定芽在枝上的发生位置固定,顶芽(terminal bud)包括胚芽,只发生于枝的顶端,腋芽(axillary bud)或侧芽(lateral bud)则只发生于叶腋(叶的近轴面与茎的夹角处),

apical dominance：頂芽優勢
依原生地不同可分为两大类:蕙兰属植株主要由叶片 (leaf)、 假球茎 (pseudobulb)、 鞘叶(sheath leaf)及肥大的根 (root)组成,叶片和鞘叶在与假球茎交接处都有潜伏芽, 这些潜伏芽的萌发受到顶芽优势 (Apical dominance)控制,在假球茎膨大部位上方的潜伏芽较不易萌发,
