Resumen:
We report the morphological and anatomical characterization of the primary
and secondary structures of root systems in Duchesnea indica, Fragaria vescaDuchesnea indica, Fragaria vesca
and Potentilla tucumanensis, three species that show a main tap-root with a
variable branching pattern. Mother plants of F. vesca present main roots with
a primary structure of the diarch type, a secondary structure with a polyderm,
and adventitious roots from diarch to pentarch stele. Mother plants of D. indicaPotentilla tucumanensis, three species that show a main tap-root with a
variable branching pattern. Mother plants of F. vesca present main roots with
a primary structure of the diarch type, a secondary structure with a polyderm,
and adventitious roots from diarch to pentarch stele. Mother plants of D. indicaF. vesca present main roots with
a primary structure of the diarch type, a secondary structure with a polyderm,
and adventitious roots from diarch to pentarch stele. Mother plants of D. indicaD. indica
and P. tucumanensis do not form adventitious roots, the primary structure
is a diarch, and the secondary structure lacks a polyderm. Daughter plants ofP. tucumanensis do not form adventitious roots, the primary structure
is a diarch, and the secondary structure lacks a polyderm. Daughter plants of
D. indica and F. vesca form adventitious roots with variable steles, from diarch
to polyarch. Tracheids were only observed in F. vesca and P. tucumanensis. Our
results show that the number of protoxylem poles, and the occurrence of tracheids
and polyderm constitute valuable diagnostic characters for the identification
of these species.and F. vesca form adventitious roots with variable steles, from diarch
