DOMINGUEZ TORREJON, Gilberto  y  DONAYRE GOMEZ, María Luz. Aclimatization of Uncaria tomentosa (Willd.) DC. produced in vitro. Ecol. apl. [online]. 2006, vol.5, n.1-2, pp.67-74. ISSN 1726-2216.

Previous acclimatization assays of Uncaria tomentosa (Willd.) DC. (cat´s claw) in vitro plants, determined the susceptibility of the species to adapt to natural environment conditions. An in vitro created clone was selected for evaluation in the acclimatization phase and it was subjected to survival, growth and level of strength measurements, expressed in number of leaves developed. The results show that the acclimatization process has permitted a rate of 100% survival of in vitro plants, with sizes from 17.07 cm to 19.53 cm in the pre acclimatization period, with a level of strength of 7 to 14 leaves approximately. The figures show that these have not had incidence in the mortality. The delayed development of in vitro plants in several substrata did not show significant differences in the size of the plants (20.8-24.8 cm.). Despite of having a slight effect of lower increase in one of the substrata, their size is considered homogeneous. The final strength of in vitro plants, expressed in number of leaves did not show significant differences due to substrata, allowing these plants of homogeneous vigor to be considered suitable to be used in the fields.
