由GUNNAR ERDTMAN提出的酵解方法在孢粉学中仍然是一种非常受欢迎和非常成功的技术。然而，除形成花粉外壁的孢粉素外，乙酰解会破坏所有花粉物质。现代孢粉学在植物系统学和系统发育中的应用必须考虑所有的孢子皮特征，而不仅仅是外表的特征。忽略内部可能会扭曲孢粉学的一些主要方面。这可以通过薄的外壁结构的完全破坏或大体改变（例如在Beilschmiedia， Strelitzia）和孔的澄清（例如Polyalthia， Fissistigma, Calluna）来说明。在我们看来，对乙酰化和非乙酰化花粉的研究对于花粉结构和功能的平衡是必要的。
The acetolysis method introduced by GUNNAR ERDTMAN is still a very welcome and highly successful technique in palynology. However, acetolysis destroys all pollen material with the exception of sporopollenin that forms the outer pollen wall, the exine. Modern palynology in its application to plant systematics and phylogeny must consider all sporoderm characters, not only those of the exine. The neglect of the intine may distort some principal palynological aspects. This is illustrated by cases of total breakdown or gross modification of thin exine structures (e.g. in Beilschmiedia, Strelitzia) and by the clarification of apertures (e.g. Polyalthia, Fissistigma, Calluna). In our view the investigation of both acetolysed and non-acetolysed pollen is obligatory for a well balanced view of pollen structure and function.
