Storage root
formation
The formation of
storage roots can be in clusters around the stem. If the root stalk that
joins the root to the stem is absent or very short, it forms a closed cluster.
If the stalk is long, it forms an open cluster. In some cultivars, the
storage roots are formed at a considerable distance from the stem
and therefore, the storage root formation is disperse or very disperse.
Storage root
surface
The storage root
surface is usually smooth but some cultivars show some defects such as
alligator-skin, prominent veins, horizontal constrictions or longitudinal
grooves. Lenticels are also located on the surface which can be
protuberant in some cultivars due to excess water in the soil.
