在凤梨科中唯一的染色体研究是Lindchau（1933），他报道了几个属的染色体数目，总共约有50个种。Matsuura & Suto（1935）也发表了一些计数。这些结果表明，通过他们声称要揭示的基数的变化，细胞学支持同质亚科Pitcairnioideae和Tillandsioideae的分类分离，在它们之间具有更易变的Bromelioideae。与这些早期的结果相反，目前的研究表明，凤梨科的细胞学是非常均匀的，在基数或倍性水平上几乎没有变化。从广泛的形态多样性（Mez，1896）和生态适应性（Pittendridge，1948）来看，这是值得注意的。
The only chromosome study of any magnitude in the family Bromeliaceae is that of Lindchau (1933) who reported chromosome numbers for several genera, and about 50 species in all. Matsuura & Suto (1935) have also published some counts. These results suggested, by the variety of basic numbers they purported to reveal, cytological support for the taxonomic separation of the homogeneous subfamilies Pitcairnioideae and Tillandsioideae, with the somewhat more variable Bromelioideae holding an intermediate position between them. Contrary to these early results, the present investigation has revealed that the Bromeliaceae is cytologically very homogeneous throughout, with little variation in basic number or level of ploidy. This, in view of the wide morphological diversity (Mez, 1896) and ecological adaptations (Pittendrigh, 1948), is somewhat remarkable.
