What is it about?

Wheat Kernels are described and classified Based on Geometric Models. Kernels of diploid einkorn and ancient tetraploid emmer varieties adjust to the lens and have curvature values in their poles superior to modern “bread” varieties. Kernels of modern varieties (hexaploid common wheat) adjust to an ellipse of aspect ratio = 1.6, while varieties of tetraploid durum , emmer and Polish wheat and hexaploid spelt adjust to an ellipse of aspect ratio = 2.4.

Why is it important?

The method may be of practical application in the validation of results of digital analysis applied to shape comparisons.


Seed shape can be quantified by comparison with geometric figures. This is an interesting tool in plant phylogeny as well as to relate morphology and genetics.
