1. The tubers of Dioscorea floribunda Mart. & Gal. and D. spiculiflora Hemsl. arise from a ventral bulge between the first shoot and true root of the seedling. This bulge results from meristematic activity of the ground meristem.2. Primary growth of the tuber is by multiplication and thickening of the primary thickening meristem and by differentiation of the cells so produced. 3. The tissues of the tuber arising directly from the ground meristem are the storage parenchyma, its enclosed bundles… 
Ontogeny and morphology of the tuber of Dioscorea floribunda Mart
The tuber arises from the hypocotyl due to intensive unilateral activity of the primary thickening meristem. The resulting growth thrust produces a tuber apex, which consists of a drawn-out dome of

TLDR
The tuber is an integral appendage of the hypocotyl secondary body, whereas the tubercle is a sympodial rootstcck, the two together forming a perennial organ through activity of the same primary thickening meristem.
Application of anatomy and HPTLC in characterizing species of Dioscorea (Dioscoreaceae)
TLDR
A detailed investigation of the anatomy and micro-morphology of the rhizomes and tubers of five different species of Dioscorea is provided and the diagnostic key of anatomical features included in this paper can help distinguish the investigated species unambiguously.
Techniques and Problems in the Propagation of Sapogenin-bearing Yams from Stem Cuttings
TLDR
It was found that an important factor in the propagation from leaf-stem is the use of young, vigorous, succulent leaves, and that hormones stimulate root growth and that fungicides are not necessary.

TLDR
The result showed that micromorphological characters of stem, leaf, and tuber can be used for interspecies identification and classification of Dioscorea, but is not significant for intraspecies classification and identification of D. alata cultivars.
The development of the tuber in seedlings of five species of Dioscorea from Nigeria
Tubers in all five species develop from the hypocotyl region of the seedlingS. A perivascular cambium arises cutting off mainly starch-storing parenchyma and collateral vascular bundles to the
Characterization of Corydalis (Papaveraceae s. l.) and Dioscorea (Dioscoreaceae) Species: 1. Root Anatomical Characters
TLDR
Resin embedding methodology was evaluated for authentic herbal medicinal identification using tubers or rhizomes of Corydalis and Dioscorea using resin embedding approach makes easier to dissect the herbal drugs.

Get the shovel: morphological and evolutionary complexities of belowground organs in geophytes.
TLDR
The terminology commonly used (and sometimes misused) to describe geophytes and their underground organs is clarified and key evolutionary patterns of the belowground morphology of geophytic plants are highlighted.
Effect of potassium on tuber yield and nutrient uptake of yams
The highest tuber yields of D. cayenensis and D. rotundata (var. aro) were produced using 30 kg K,O/ha, whereas D. alata and D. rotundata (var. efuru) gave optimum performance with 60 kg KtO/ha.
