“Leaf and stem anatomy of four Dioscorea species D. rotundata, D. alata, D. bulbifera and D. dumeturrn:- Effiong, Iberedem .E.
ABSTRACT
The edible tubers from different species of Dioscorea are a major
source of food and nutrition for millions of people in the world. The anatomy
of the organs (leaves and stems) of Dioscorea rotundata, Dioscorea bulbifera,
Dioscorea dumeterum and Dioscorea alata were examined and compared with the aim
of identifying or delimiting the existing characters between these species.
Anatomical studies were carried out on the
leaves and stems ofthe four species. The result obtained from this
investigation showed features of anatomical importance in the leaves and stems
ofthese species. Results from epidermal cells showed differences in the shapes
and sizes of the epidermal cell walls. The result from the investigation has
proved that the leaf and stem anatomy of the four dioscorea spp exhibits
characters like trichomes, spindle, nail, curve-straight appearance in shapes
and the presence of stomata on the lower epidermis layer of the leaf, while stomata
were absence in the upper epidermis (hypostomatic) in nature. This could be included
with other reliable attribute of this species in an attempt to fashion out an authentic
classification among the varieties of Dioscoreae. This observation will be usefid
and contribute to the further classification ofDioscorea species
