Vegetative propagation of Cecropia obtusifolia (Cecropiaceae)
Cecropia is a relatively well-known and well-studied genus in the Neotropics. Methods for the successful propagation of C. obtusifolia Bertoloni, 1840 from cuttings and air layering are described, and the results of an experiment to test the effect of two auxins, naphthalene acetic acid (NAA) and in...

Se discuten métodos exitosos para la propagación de C. obtusifolia Bertoloni, 1840 de fragmentos de troncos y acodos aéreos. Acontinuación se presentan los resultados de un experimento para examinar los efectos de dos tipos de hormonas (NAA e IBA) en la producción de raíces adventicias en fragmentos de troncos. En general, los fragmentos de C. obtusifolia responden bien en la producción de raíces adventicias (y sobreviven al azar 58.3% de los cortes), pero el método de acodos aéreos funcionó mejor (sobreviven al azar 93 %). El uso de hormonas resultó en raíces de baja calidad en comparación con cortes sin hormonas. Experimentos en el futuro que usan Cecropia pueden beneficiar al usar plantas isogénicas producidas por propagación vegetativa.

In general, C. obtusifolia cuttings respond well to adventitious root production (58.3 % of cuttings survived to root), but air layering was the better method (93 % of cuttings survived to root).

Cecropia is a relatively well-known and well-studied genus in the Neotropics. Methods for the successful propagation of C. obtusifolia Bertoloni, 1840 from cuttings and air layering are described, and the results of an experiment to test the effect of two auxins, naphthalene acetic acid (NAA) and indole butyric acid (IBA), on adventitious root production in cuttings are presented. In general, C. obtusifolia cuttings respond well to adventitious root production (58.3 % of cuttings survived to root), but air layering was the better method (93 % of cuttings survived to root). The concentration of auxins used resulted in an overall significantly lower quality of roots produced compared with cuttings without auxin treatment. Future experiments using Cecropia could benefit from the use of isogenic plants produced by vegetative propagation. |
