sinensis present cuticle, epidermis, and mesophyll, crystals of Calcium oxalate, sclereid cell, and trichomes.
Internally, the crystals of calcium oxalate, sclereid cell remained preserved.
The Prunus amygdalus stem is composed mainly of sclereid cells (or fibres) with about 25 [micro]m in diameter and a wall having about 10 [micro]m of thickness.
However, some characteristics were not confirmed, like: cuticle lack; spongy parenchyma lack; sclereid sheath; exocarp becoming strongly suberized, collapsed and sometimes separated from mesocarp; mesocarp constituted by a middle layer, unistratified of small parenchymatous cells, containing prismatic crystals; and the inner layer of endocarp suberized.
Six differential characters: epidermal cells rectangular (104), oval (105) or round in outline (106) with outer wall thick (107) or thin (108); hypodermis with sclereid cells (109).
The strength of a fiber or sclereid depends on the thickness of the secondary cell wall.
is anatomically distinguished from the other studied species by having more layers of sclerenchyma and meristeles on the stipe, and by the lack of sclereid nests on the rhizome.
Terminal tracheids present a welldeveloped sclereid sheath (Fig.
The species collected in the Pantanal and prepared according to the usual techniques for anatomical studies showed similar structural characteristics, and data on the arrangement of vascular bundles in the midrib and petiole, as well as the form and distribution of sclereids, were consistent.
In the fruit set stage in the "Clapp's Favourite" fruits, sclereids aggregates formed 2-3-cell clusters or were single, whereas in the "Conference" they were more numerous and contained several cells (Figures 6(a), 6(c), and 6(d)).
