ABSTRACT: Fruit, seed morphology and seed coat sculpturing
were recorded for 10 species belongs to 9 genera and five tribes of
Brassicaceae in eastern region of Saudi Arabia by using light microscope (LM)
and scanning electron microscope (SEM). Four seed patterns were recognized
based on surface sculpturing pattern; Reticulate, with four subtypes, undulate,
verrucate and ocellate. The results of numerical analysis showed that species
were grouped into two major clusters and each cluster divided into two groups.
The cluster analysis indicates that the characters of fruit and seed are very important characters for identification and taxonomical
classification of the tribes. The results indicate that the most tribes of Brassicaceae are polyphyletic, and some are related to
each other’s as Lepidieae, Alyssieae and Sisymbrieae.
