Abstract

In this study,seeds
of 5 species of Acanthophyllum in
Turkey were examined with stereomicroscope and scanning electron microscope
(SEM) to evaluate the systematic significance of seed microstructure. The seeds
of Acanthophyllum were characterized
by oblong or obovate shape. Seeds dorsal and ventral side are generally convex.
The largest seeds are found in A.
acerosum (2.45 mm in length and 1.16 mm in width). The smallest seeds are
found in A. verticillatum (1.61 mm in
length and 0.84 mm in width). Seeds surface of Acanthophyllum species are fine tuberculate arranged with elongate
or polygonal cells like jigsaw puzzle. The shape of suture is sinuous, undulate
or dentate. The color of seed is reddish-brown or yellowish-brown. The radicle
is on the one side of each seed and just out beyond the hilar notch. Color of seeds, seed length and width, hilum
length and width, suture shape, testa cell shape and the number of suture
points per plate are important characters in differentiating Acanthophyllum species. By this study, similarities and
differences between the species of Acanthophyllum
genus are revealed and contributed to taxonomic studies.
