顶端优势顶端优势apicaldominan物顶芽生长对侧芽萌发和侧枝生长的抑制作用，包括对侧枝或叶生长角度的影响。相关性抑制的一种表现。大多数植物都有顶端优势现象，但表现的形式和程度因植物种类而异。顶端优势强的植物，几乎不生分枝；顶端优势弱的，能长出许多分枝。顶端对侧芽的抑制程度，随距离增加而减弱。因此对下部侧芽的抑制比对上部侧芽的轻。许多树木因此形成宝塔形树冠。顶端优势的强弱随植株年龄而变化，同时受营养和环境条件的影响。幼龄植物顶端优势强，老龄时减弱；光强过低，土壤通气不良或水分亏缺，顶端优势增强；氮素供应充足，顶端优势减弱。顶端优势的强弱随环境而变化，可使植物按照水分与营养的供应情况来调节分枝数。解释顶端优势现象，主要有3种学说：①营养学说。认为顶芽中的顶端分生组织的细胞生长迅速、代谢旺盛，所需营养物质较多，优先享用由根部和叶片运来的营养物质，使侧芽得不到充足的养分，从而生长受到抑制；②生长素学说。认为顶芽是生长素合成的中心，在这里合成的生长素沿茎向基部运输，抑制侧芽生长；③营养调运学说。认为顶芽中顶端分生组织的细胞生长活跃，代谢旺盛，合成大量植物激素，顶芽的高浓度激素促使营养物质向顶芽调运，使侧芽得不到足够的营养物质而受到抑制。农业生产上，常用打顶的办法去除顶端优势，以促使侧芽萌发、增加侧枝数目或促进侧枝生长。
