保留芽或分生组织的储备以备偶然损伤后恢复，这在植物中很普遍。然而，拥有花蕾库并不是普遍存在的。据推测，保持花蕾是有成本的，对某些物种来说，这些成本超过了收益。本文件有两个主题。我们估计了构建和维持芽的碳成本，并回顾了芽在不同情况下的其他成本和效益。其次，我们开发了一个框架，用于定量地思考成本和收益。根据现有的数据和一些合理的假设，花蕾的绝对碳成本似乎很小。因此，许多物种不维持芽库的事实表明，芽的好处对它们来说可能微不足道。或者，芽可能会带来其他成本。芽保护或与芽协调的保护区的成本似乎是可能的候选人。
Retaining a reserve of buds or meristems for recovery from I occasional damage is widespread among plants. Yet possession of a bud bank is not ubiquitous. Presumably there are costs to maintaining buds and for some species these costs outweigh the benefits. This paper has two themes. We estimate carbon costs of constructing and maintaining buds, and review other costs and benefits of buds in different situations. Second, we develop a framework for thinking quantitatively about the costs and benefits. Given available data and some reasonable assumptions, the absolute carbon costs of buds seem small. So the fact that many species do not maintain bud banks suggests that the benefits of buds may be negligible for them. Alternatively, buds may carry other costs. Costs of bud protection or of reserves that are coordinated with buds seem likely candidates.
